UvIn this video I will do a complete walkthrough of the 3 most common ways to power LED Strips as well as how to inject power into your longer led runs. I am definitely not an expert when it comes to powering led strips but the goal of this video is to hopefully show you that its not as hard or complex as you might think. In all my projects where I have powered things the way shown in the video, I generally have the maximum current on the WLED limiter set anywhere from 850 mA - 2000 mA which has always been bright enough to achieve the desired results. I also don't leave my led lights on overnight and will generally be in the room when they are turned on. Even though I have never had any issues, make sure to consult a trained professional if you are worried about safety.

[@minifireball1170]

Hey Chris, I am trying to make a parts list for everything I would need to power 4 5m 60 2812BECO light strips. So far I have the strips, 18 gauge wire, ESP32 Development boards, 2 of the 60 amp power supply's and the necessary 3 wire power cables, and Wago connectors. Is it necessary to have the 20 gauge extension wire or can the power injection be done with the 18 gauge? Did I leave anything else out? Thanks

[@IntermitTech]

Love the video, but I do have some serious concerns about the methods you explain...... now I don't want to be mean or degrading so please take this as constructive criticism, nothing else meant with it, we're all here to learn! I'm also fully open to discussion or questions, etc! Overall assumed values: 300LEDs of ws2812b when properly injected can use up to 13Amps (65w) real-world, I've done extensive power measurements and publish a real-world power sheet for lots of types of LEDs to know what to expect and calculate with. For general usage I normally use the 50% white value which would be 6,5Amps or 32,5w to run single colors and effects at 100% brightness. A single injection point cannot take in more then ~4Amps before voltage drop becomes too high and it basically won't do much anymore. If you want to power a 300LED strip of ws2812b for 100% RGB white you will need proper sized wires and front + middle + end injections, anything less then that and they won't be running at their full potential. So in all scenarios shown you where running limited. Although that can be fine, this will also in part limit smoothness and such. Each LED has a Red, Green and Blue diode which have 256 steps of brightness. Limiting them also limits the range they can use and thus will things more "choppy". Basically 50% power means it now only has 128 steps, not 256. Now the WLED limiter is good and doesn't do this per LED but overall and in real-time, but still, using 850mA will for sure show this for instance. Setup 1 - 2000mA phone charger A. Make sure to test this charger can deliver a sustained 2000mA and won't overheat B. The ESP board (circuit traces) and USB socket are not rated for anything close to 2000mA C. The included USB cable probably already has quite a bit of resistance and will start to drop voltage over 1000mA D. Dupont wires, please please don't use over 500mA on these Running addressable LEDs like this can be done, but please don't exceed 850mA, even that is stressing it already in my opinion. Now this can be fine in some situations where you don't have a lot of LEDs or don't mind running them at low brightness, still, it can be dangerous (fire!) running more power through this setup, the hardware is NOT designed for it (dupont really shouldn't exceed 500mA). Most likely the resistance on the USB cable is already lowering voltage coming into the ESP board (and with it Amps) and then the dupont wires will lower it even more, but still. This is not the correct way to run any decent amount of LEDs... Setup 2 - 5v 10Amp power supply Already much better! But still I have issues.... A. Those barrel plug adapters, please please don't use them for 5v, it's stupid they come with them, they are not to be used over 3Amps continuous or will melt. But just snip off the barrel plug on the PSU wire and use those wires directly. :) B. 18AWG wire is nice, but since you are only using it to power the ESP using dupont wires here would have been fine actually. :) But as said, this setup is much better but won't draw more then 4Amps to maybe 5Amps before voltage drop becomes too much of an issue again. Still that can be fine for running single colors and some effects. It would however be better to use a 6 or 7.5Amp power supply since then if it has OCP that could provide a little bit of protection against shorts or other issues. A fuse here might be a good idea but the PSU not being giant also gives a bit of protection already (f it's good quality). Setup 3 - 5v 60Amp power supply Better but also somewhat worse. When using such big power supplies their internal protection mechanisms will not work for you anymore so you need to add protection yourself in the form of a fuse per injection line, etc. A. Fuses! B. Using a 20AWG 5m/16ft wire for 5v really doesn't work. In what you showed with front + end, it will equalize voltage a little bit, but really doesn't do enough. Voltage drop calculator says 16ft/5m of 20AWG doing 4Amps will have 1.3v of drop just on the wire alone which then becomes heat.... C. Adding the second strip make this problem worse since it's now not an edge connection but a middle injection capable of delivering up to ~8Amps into the strip effectively but as shown in the video, it already has 2.6v drop on just the wire alone. Now because it's 5v and the resistance makes the voltage drop it probably won't burn up, but it's not a good situation either as is kind of shown by the result in the video too. So basically, all scenarios are seriously under powering the LEDs, this is also why at some point you won't see a difference when moving the sliders around in WLED for instance. This can be ok if that's a choice, but still. All scenarios also only work because you are attaching the very short wires on the LED strip directly to the power source, using the same type of wires even just a little bit longer will make all of the scenarios fail basically. Now you mention in the video you aren't an expert in this and learning yourself, that's good! I kind of partly then think maybe not make "advice" videos like this on the subject but I also get you need to start somewhere. Maybe next time do a bit more analysis of your setups, include voltage measurements using a multi-meter at the start and end of the wire when set to a single color or 100% RGB white, do the same at the start middle and end of the strip, etc.. That would make it a bit more scientific and you'll start figuring out more why some of the stuff you are seeing is happening and what is a good situation and what isn't and can potentially be dangerous. :)

[@ChrisMaherDIY]

Thanks so much for taking the time to respond with such great information! I'm all about learning and it sounds like you would be a great person to learn from! Do you do this for fun or is it part of your career? Thanks for all the advice and for watching! Also, i'm a huge fan of your work. What video of yours goes into this type of detail? I'd love to link it in the description of my video so people can watch.

[@MrTubertub]

Thank you for this very detailed technical answer and carring about our safety. Can you please let us know what is the best simple power supply and wires to Buy for powering a WS2812B led strip of 5 meter and 2 x 5 meter with 300 to 600 leds. Thank you

[@Filip-se1mi]

@@MrTubertub The reason why you will probably not find a video that clearly states the wire sizes and power supplies is because they will all end up with the same answer "It depends". Every setup is unique in regards of lengths and power requirements, some use more or less lights, straight wires instead of moving around obstacles, those kinds of things.. There are some resources that explain each step more in detail, but I do not want to hijack this video to promote others. The most important steps are explained here, keeping those in mind should improve the safety of any installation you create. The very dirty short answer would be to first calculate (roughly) the maximum amount of power your strip will need. As Quindor stated that would be about 65W for WS2818b strip with 100% RGB white. with the recommendation to calculate mostly for 50% RGB white, that then translates in to about 33W for a 5 meter strip (1 roll of 60 LED/m or 16,4ft) and to 65W for a 10 meter strip (2 rolls of 60LED/m or about 33ft). Now that you know the power, you can base the rest of the calculations on those numbers. First of all, the power supply. Generally best practice is to have a PSU can can supply more power than the maximum you want from it. Good rule of thumb would be to have about 10-15% more power than required. Following that rule you'd look at buying a PSU capable of doing about 40W for a single strip, and about 75W for 2 strips. That's the easy part. Moving on to the wires themselves.. Since power always tries to balance things out in a perfect world, you can start looking at the number of injection points you require to transfer all those amps to the LED's safely. For the 65W example, that would be (65W divided by 5V) 13A. Knowing that a front/end injection can transfer about 4A in to the strip, and a middle injection about 8A, this would be possible by injecting power in the front (start of the first strip), middle (between the 2 strips) and end (end of the second strip). If you'd go to for example full brightness, you'd require 26A (or 130W). In that case you will need to inject front (4A), middle of the first strip (8A), middle of the 2 strips (8A), middle of the second strip (8A) and end of the second strip (4A). Than you will be able to get (4+8+8+8+4) 32A max in to the strip, with room to spare on the 26A the strip will take. For each of these injection points you can then calculate the wire size required to safely transfer the power over the distance. Start here by measuring the distance from the power supply (or even better a fuse box) to the LED strip and note all those distances. Then pair that distance with the expected maximum power on that wire. We'll take the example of the 5m long injection wire. So that wire would be 5m long, carry 5V 8A, and needs to stay within 10% voltage drop. The 10% voltage drop is the standard tolerance of most electric equipment, unless specified otherwise. You can use a voltage drop calculator for that, and that will tell you, you would need a 12AWG wire to transfer that power, with about 8.8% voltage drop. Now I know for many people this will seem crazy and they won't believe you need such a large wire for this.. But the truth is, if you want to transfer low voltage over a large distance with a few amps, the wire almost needs to be perfect to not drop more than 10% voltage. Higher voltages have a better tolerance since there is more room to play with. For example 5V 10% is only 0.5V while if you use 12V 10%, that's already 1,2V tolerance. Go to mains voltage and the drop allowed is even bigger in terms of voltage. Hope this helps!

It's great that you mention not just how much power these led strips use, but that not all the power can make it from one end to the other. A while back, I put up a bunch of warm white led strips and noticed that one side of the room was brighter than the other. Voltage drop from one end to the other was enormous.

[@ChrisMaherDIY]

I'm just getting into WLED and this has been useful explaining runs and the concepts of injecting additional power

[@amirhaynes6016]

This is exactly what I was imagining I’d have to do. I’ve got a 48” run and plan on going 90% brightness with these same LEDs from Amazon. I don’t want to run any cables down the wall, so I plan on starting it from a closet. I’ll have to run 4 pairs of wires down to the third strip to have 0 degradation of power. You’re the only person I see who actually explains and demonstrates it all step by step thank you so much!

[@ChrisMaherDIY]

You are very welcome! Thanks so much for watching and taking the time to comment!

[@cometmace]

Great walk through. This is the only video I've seen that clearly shows an injection wire running all the way from the power source, along side the LED strip to the far end. Thanks for clearing that up! 13:09 - There's an obvious color change for both the un-injected and single injected wiring for the two parallel LED strips. 14:25 - *I* see very little color change when only the beginning and middle injection points are enabled. Shouldn't this look exactly like 13:09?

[@ChrisMaherDIY]

Thanks so much for watching and I'm glad you liked the video. I went back and watched the sections and you are right. My only guess as to what the difference might have been at the 14:25 point was even though I know I had the limiter turned off, I might have fogot to turn the brightness all the way up on the WLED brightness slider and therefore it was not as obvious as a difference. Good catch!

[@simonsardine2925]

Ok so I gave this a go .. and how fun is this! I'm gonna invite my mates over with their sons so we can have a LED workshop and make some lights for church. Thanks again :)

[@wyattspop]

Just an FYI, you could look into 6 amp "mini-amplifiers" instead of that bulky one with the protruding pins you use, the "mini-amplifiers" are no bigger than a usb flash drive but half as thick, so much easier to hide when you hang your lights, and they do the same function, keeping the remote controls in-sync and are a buck or 2. They also help with injection just being wired into the sequence

[@ChrisMaherDIY]

Thanks so much for the great suggestion! I've never heard of mini amplifies so I'm very intrigued! Hiding big stuff is sometimes a nightmare so anything to help on that front would be amazing! Thanks so much!

I used an old surface tablet adapter with usb and rated at 5v 2.5A. It was perfect for powering my small controller and about 3 strands of 50 bullet nodes. Once I plugged in 2 more strands I saw some drop off but when my sequence hit the all white segement, anything beyond the 2nd strand turned pinkish orange instead of white. These are a great way to see where your drop off will happen. I have purchased a 350w 70A big boy power supply to wire up my tree with (and a few other models) I'm here to confirm my understanding of wiring the injection points and you confirmed I understood it correctly.

Hey Chris, I STAND CORRECTED! Although my mini-amp idea does work keeping 3 strands in-sequence, your wifi board is vastly, ridiculously BETTER for it's functionality, and is so worth it's larger size. You can easily hide the wifi board by simply using longer wires and having it end in anyplace you wish. If you're lighting a bedroom for example, the obvious place is a closet, you'll want to do this with the 60 amp supply unit for sure as it's the size of cigar box. PAY ATTENTION TO CHRIS, I've watched dozens of videos and tried many configurations, power supplies and Chris's video is the only one that is both accurate and user-friendly

Great! I just bought 4 - 5 meter strips , a 60A 300w ps and you proved that I'm going to have to run alot of injection wire to get even white from pixel 1 to pixel 1200.

[@graphguy]

@@ChrisMaherDIY Thanks with that thought. I have set up the whole 1200 LEDs in the garage in a test situation while I am mounting the tracks on the roofline so that is ready once I get the power figured out to a bare minimum of wires, injection points etc. PS really love the lighting ideas you bring forward in your vids.

@@ChrisMaherDIY ok . I'm a tad confused. I have 1500 (60/m) 5v leds up in 5 strips. I have power at the start and I added one home run at the very end and that is it. Every single WLED effect works just fine and looks great! So how come every person says that in that situation I would many injections?

[@ChrisMaherDIY]

@@graphguy You are confused just like I was and still am to some extent. So when people ask how much power will they need, there is the theoretical amount you will need if you wish to run the lights at full brightness and on white, and then there is the power (much less power required) that is needed if you are only planning on running animations and colors. Thats why I generally say, it will depend on what you are wanting to do with the lights. As you have noticed, you dont need a lot of power to run most animations and if things look good and your happy, then your done! But my guess (and I could be wrong) but if you turn the lights to white and at full brightness, you might see some color/voltage drop and would maybe do some more injection. Hope that makes sense!

A few comments, i am not an electricion but in theory: You should crimp wires that are not solid core when used with a screw in mechanism, otherwise the cables could move changing the diameter of the cable effective and increasing resistance and heat, causing a fire in worst case. I think in the 2nd power example you could just use the 2 adittional wires, the esp also only needs to be connected to data if I am not mistaken

[@ScottMicale]

This is a great video. Thanks for making. If you use the big power supply could you use the +/- terminals for all power and the injection points? Or do you need to use the other 2 +/- terminals on the power supply for the injection points?

[@montoyajj]

How’s it going, great in depth video! I’m new to all of this, would there be any drawback to using jumpers instead of soldering for the 5v 10amp power supply?

[@wild8wire]

I’m late to the party and just now diving into LED strips (I have a firm background in electronics in general though). Really enjoy your videos, thank you SO much. My question is routing injection wires. To minimize the number of wires or channels visible outside the LED strip, are you running the extra power wires inside the LED channel? Or do you actually leave them external and break into the strip where the wires need to connect?

[@jeffro.]

This is VERY USEFUL. It shows how to properly power long strips of LEDs, instead of just powering from one end, then wondering why the strip or matrix burned out! The wires connecting them together aren't heavy enough to conduct all that amperage through, so you have to "inject" more power through the leads provided. Great video! Hopefully this will help some of the no-brain Gen-Zers out there, trying to get though life without EVER learning anything except what they call "hacks" that allow then to meander along without ever becoming knowledgeable about anything. Heaven forbid they might accidentally learn something. And, this was appropriately titled, for a change. You could've just titled this "Comparison of Power Supplies and Methods of Powering LED strips." That way, it's easier to find in s search. I hate it when ppl mis-title their videos, just to get lots of views. YT should encourage PROPER TITLING, instead of encouraging MIS-titling the way they do now! It just makes sense. After awhile, there's trillions of videos online, but nobody knows what any of them are about without having to watch each one until you find what you're looking for. That's just crap, and a massive waste of time. But, hey, does YT care?! Of course not. They just want VIEWS.

Hey Chris, thanks for your videos! They have helped me a lot getting started with wled. When using the 2A phone charger, you are powering the leds through the esp32, have you ever experienced any issues, since wled says to not go above 850 mA, otherwise risking frying the esp? Would love to run mine on the full 2A, does it matter how long the lights are on? Sorry for those basic questions, my understanding of electricity is fairly limited.

This is really helpful! Question: I am doing a really complex installation in my office and every LED strip run is attached to the previous in sequence. I've done the math and found one of these "big guy" transformer power supplies that will power the whole room, but there will be 9 or 10 injection points and the transformer only has 3 + & - terminals. Can I attach more than one injection run to a terminal? Or is there anything I could buy or make to expand the terminals?

[@andrescastro6538]

quick question to connect 20 meters of strip ( 5 meters sets x4 ) do you recommend 12v or 24v? i will like an option i can use a single power supply to power all 20 meters from the beginning - i assume at the end of each strip i will connect the data cable to the data cable of the other strip ? also a single controller can run all 20 meters correct .. thank you so much for all your time and videos.

[@doubleT84]

For my project I have 12 x 1m segments (2 walls with wooden beams every meter) and I was told to only connect power on one end of each segment and ground on the other end, to help keep brightness consistent. Any concerns about heat, also with your 3 strips?

[@ChristianSchebitz]

Thx!

[@RetroWaveArcades]

Great video! I would like to add something to this. You used 5m 5V 60 led/m strip. 1 meter consumes 18W at full brightness. That means that you will need 3,6A for full white. With 5m it will be 90W and at least 18A power supplier will be requaired. 1A=1W / 1V 1W=1A * 1V 1V=1A / 1W easy math ;) It also recommended to have addicional 10% of power in your project. Just for LEDs. With 5V power supply You can power up your other 5V devices such as HDMI splitters, raspberry pi's and so on.

[@ChrisMaherDIY]

Thanks so much for watching and for the great advice! That does make it seem simple!! Appreciate you taking the time to share your wisdom!

[@MRES3]

I have the 5v 60amp power supply on one end and the 5v 10amp in the emd witch made a huge difference but i notice with the power supply in the end some of the led's stay on or be acting weird, is because the power supplies need to be the same or? Also can i just add the red and black from led's directly to the power supply and just add the green to the controller device?

[@Tarecco7]

Hi Chris, my Leds doesnt turn on at all. do you know why? i followed your instruction.

[@nikilragav]

Thanks for this detailed comparison! I was wondering if you've tested or seen documentation on how much air the 60A metal power supply needs? Where do you usually hide the supply and the microcontrollers? Do you need to have some kind of false wall so that there's like a 6 inch gap?

[@ChrisMaherDIY]

You are very welcome! Thanks again for watching! I have not tested that out yet. I really don't take a scientific approach to any of this. I generally just hook things up and see if it works and go from there. As for hiding things, i mostly just put them behind furniture or drawers or electric fireplaces. Its for sure not fancy but as long as I cant see it, it does not bother me.

[@victormdp]

What about if you want to add two 5V sensors, let's say for the top floor of the house and the lower floor (so the sensors enable and/or disable the lights); would you still be able to connect both sensors with the second option (10Amps) with one 300 led strips and your led controller, or would it require a bigger power supply?

[@HugRunner]

Thanks for this video! I'm wondering a bit about the big power supply. If you had e.g. 6 strips, I assume you could connect them using a 3x2 pattern, i.e. 2 red/white on each connector on the power supply? Pretty much all power supplies I see only have 3 positive and 3 negative, even if they allow for higher Amps, but it seems rather overkill to only connect at most 3 strips to these.

[@VP411Designs]

Awesome helpful video. What do you recommend for DIYers who are setting up LED Strips as main lighting source in ceiling with profiles built into the entire ceilings in long extended strips on entire ceiling space covering about 1000 square feet? Main question here is power source? Controller Source? And how to control individually or together as one? If I install a LED Strip all over my ceiling on the entire ceiling on every room and hallways how/what is the best way to setup from LED product, power product, and controller product.

[@ChrisMaherDIY]

Thanks so much for watching and those are some great questions! I have never tried doing something that large so I would just be guessing If I tried giving you advice! I will say that if you are using for a main lighting source, finding a good diffuser will be key. You want to find one that lets a lot of light through, but also diffuse it so you wont see the hotspots. If your only doing white then the job becomes easier but if you want all the colors then you would need to go with a strip that has all the color options as well as a dedicated white led. And for large installs like that, my guess is 24v led strips would be what you would end up going with because they would require less power injection but I have really not worked with any of those strips yet! Hopefully someday down the road I will be of more help on larger questions like this but I would recommend taking a look at some videos over at The Hook Up, DrZZZ or QuinLED. They are a lot smarter than me!

[@laiserfish]

Hey man, I know it's a bit of an older video but i was trying to get your opinion on something. I want to run those EXACT same LED strips along the top of my room through diffuser channels, and i was planning on using the big power supply and power injection run through the channels. The main issue for me is the fact i'm using 3 5 meter strips (60led/meter) in total to wrap around my whole room. I am unsure if this power supply can fully power all 3 strips connected together, and if the controller would be able to be used for the whole thing? Would I need more than one controller? Thanks!

[@hazeeq3650]

Love the video, btw why do you soldered on the esp32 for 60amp and 10amp and not on the 2amp, just a jumper wire?

[@KevinTaddeo]

fantastic video. Thank you. What is the equation I need to perform in order to make sure I order enough power? Example, I am looking to run a 100ft run. I don't want to have 10 of those boxes.

[@howiestoffberg]

great video.....if your strips are in a straight line, wouldn't injecting more power say at the end of 2 five metre strips require a ten metre run from the power supply thus having voltage drop?

[@keekee4697]

Id like to run x2 5m 300 leds on a duel controller box. So the box would have in total 10m 600leds. The leds are 5v each strip. So would i use a 5v power supply into the box? Or would these lights look really dim? Thanks

Hey Chris. I'm just trying to set up a simple white 6 ft cob LED strip within a diffuser, with a USB power supply would be efficient enough to get full brightness and are they dimmable compatible?

[@Gaskellorama]

great video, i'm running a similar set up with 3 x 5m LED strips and a similar PSU, 200w 40amp. do the three outputs of the PSU count as one power supply, at the moment with my set up I'm only injecting the start of the next strip rather than the end of the first line and start of another, as I read not to mix power inputs?

[@markjones7107]

Great Video. Really informative. Question about there being power injection wires on both ends: Have you tried connecting the 'front end' extra wires directly to the power? If so, did it end up sending power to the back end? And furthermore, would that then be able to create the daisy chain from extra wires to extra wires down the line?

[@ChrisMaherDIY]

Thanks so much for watching! That is for sure something you could do and would work just the same and you could also connect them together using the extra wires but you would still need to connect the data cable from one to the next otherwise the signal will not make the jump. Hope that makes sense!

[@DJ_K0D4]

Anyone who is watching this, please for the love of god, wrap the exposed wires going to the controllers and led strips and injections in something... Anything non conductive. Personally I always recommend using Wago connectors.

[@BishalGauli]

Hey Chris, thanks for making great videos. I learnt a lot from you, mate. Thanks again. I have a noob question, if you don't mind - what would you recommend as the best way to hide/manage the power supply and esp32 board, especially all those soldering and small wires connections? I am planning to install the LED in my kitchen and hallway (I probably need to go with the 10Amp and 60Amp power supply options)... wondering how you would keep the power supply and ESP board secure. Are there any cases you can recommend? or any other ideas? Cheers!

[@ChrisMaherDIY]

Thanks so much for watching and taking the time to comment! Glad you are liking the videos! So for the most part, I just find something to hide all the wires behind. If its out of sight then i'm not to worried. However if you are installing something and hiding the power/wires/esp board behind something is not an option and you dont want to mess with putting it behind your drywall, this is a video I just made going over what I do in that situation. Its not a perfect solution but it looks better than just a bunch of messy wires sitting there. kzbin.info/www/bejne/n5O1oWmbmrqqeKM

[@HeroClaws]

Hello Chris, i have a question, i want to put LED strip around my room (near the ceiling). The whole strip should be around 15 meters, thats around 900 LEDs. In my country i was able to find Meanwells 5V/30A PWR supply. The "start" of the LED strip will be near the end of the LED strip, with the power injection, should i be able to run 15 meter strip smoothly? Im not planning on max consumption on just white. The strip i will be using is the same one you are using in the video. Thanks!

[@kim_dongryeong]

Hi thanks for your video! Let's say I'm trying to install multiple 12/24V LED lights in a living room. For the wiring work, is it better to do it with 1) the household AC cables (like AC 220V or 110V) and then use multiple AC->DC converters? Or 2) to install (and hide) a big (high power) AC-DC converter and do the wiring work with long and multiple DC cables? I think by theory, with the 2) option, long DC cables will be used and so it'll be less efficient and there will be more energy loss (so unnecessary electricity costs on the DC cables). So my assumption is that I assume there will be no voltage drop on the AC cable of 220/110 V (for the same power, high voltage and low ampere and a thicker cable and so even low resistance) and there will be some voltage drop on the DC cable of 12/24 V (for the same power, low voltage and high ampere and a thinner cable and so even high resistance). Does it make sense? Or still is the voltage drop on the long DC cables negligible and for the sake of labor efficiency it's more practical to have one big AC-DC converter and hide it and wire thin 18 AWG DC cables around the living room?

[@benmiller1129]

Hey Chris , Great video thanks for this. My question is - what is the distance limit you can run 18awg between strips , reason I ask is that my plan is to run LEDs all around the ceiling . This would mean having some long runs from power supply and LEDs. Thanks and great video it’s been very helpful.

[@ChrisMaherDIY]

Thanks so much for watching and taking the time to comment! I have yet to do a bid install like that so I'm not entirely sure. I would probably lay everything out on the floor and see how things look after the long run for the power injection. If enough power is not getting to the leds I would either see if you could use another power source closer to the injection point or I would look at maybe using 12v led strips instead. Here is a quick walkthrough I did on some 12v led strips from btf lighting: kzbin.info/www/bejne/sJPLlXtjprh0hMU&lc=UgwRyKQC3r1Lrr1nnvN4AaABAg
