How to Install LED Under and Above Cabinet Lighting Hooked to a Wall Dimmer Switch

[@jonhansen4745]

This is by far the most concise & professional installation I have seen presented here on YT for under cabinet lighting. I'm a retired electrician who has installed quite a few of these myself and it is encouraging to see someone present this in way that is both easy to understand, yet done well.

[@ProjectBilld]

Appreciate the compliments!

[@djWOOF]

As a beginner i found this very hard to follow :(

[@scottmac386]

I too am not quite a beginner but not an electrician but you hit on many of the questions I was having when starting to plan... I have a 9' run a 22' run and a 20' run.. gonna have them all on the same dimmer switch and hopefully it will all go together.. didn't know and wasn't addressed if you need a dimmable power supply if you have a dimmer... and if not what happens? also can I use speaker wire? 16/2... I look forward to getting all the materials and putting it all together.. Awesome video and great instruction... If you haven't seen it already two resources I really liked ( but couldn't quite follow yet...) kzbin.info/www/bejne/i57SZ52BgcuqqbMsi=hBJN_EE5tFD-7Ij1 and kzbin.info/www/bejne/gZPFfHSuo9V2h7Msi=mPULdtNjWAD2IGMQ Hope it helps someone..

Glad it was helpful! I hear you, I had to do a lot of research to figure out what I needed to make it all work

Best led wiring instructions available anywhere

[@dylanogden9337]

You would be amazed by how difficult it is to find a simple explanation of DIY LED wiring. Most videos are manufacturers telling you how to use their kits, and text descriptions from distributors like Bird Dog assume you already know the parts and where you should put them. This is the first practical example I've found, and it's really helped me put the pieces together. One touch I loved was showing your struggles with the outlet box. That's the sort of situational info that is actually very important to a project, but that every DIY video in the world leaves out because it's assumed to be too specific. So, thank you!

[@ProjectBilld]

You're welcome! Glad the video was helpful

Yeah. That chunk of drywall is gone forever down that big black hole U created to another dimension in time and space...😢🕳️

[@wileecoyote837]

Wow, I wish all instructional videos were like this. Simple, to the point and most of all 100% how you should actually do it. Having been in Audio / Visual installation, interior rehab and currently an Industrial Electrician I can say that you did everything exactly the way I would do it. Actually you did some things better than I would do it, sometimes I get cheap.

[@ProjectBilld]

Thanks! I try hard to do and present things the correct way, it doesn't always mean I'm going to be 100% correct, but it's the goal! p.s. Beep Beep

[@DoNotListenToMe]

This is one of the best how to videos I've seen for how confident I feel being able to do it first time. Only thing I would recommend to viewers is running 24 volts for longer runs like this one. It helps prevent as much voltage drop vs 12 volts

[@ProjectBilld]

Thanks! 24 volts is definitely a good idea for longer runs, my voltage drop was well within acceptable range. I have long wire runs but the total length of the light strips for my kitchen was still pretty short

[@eltonnoway7864]

I've watched a lot of these "LED Cabinet and/or LED Niche lighting" How-To videos seeking information and this one was the most complete, answered all my questions, was easy to follow and all without unnecessary technical detail or annoying background music. Perfect! Thank you! -TIP to anyone considering doing this... If you can solder as shown at 5:33, it's a better option than using the click latch "locking connectors" which tend to be hit or miss in regards to getting a perfect connection. Many times you have to latch and unlatch the connectors or wiggle the wires in order to determine which of the connectors you installed has a flaky connection and preventing your light strip from lighting.

[@GeekyDad84]

This was exactly the inspiration I needed! I've built all sorts of LED projects, mostly automotive focused, over the years. Plus, I spent many years in low voltage world doing custom A/V, HT, automation and then into the Data Center world. We're finally about to kick off a big home reno project and our Kitchen it's getting gutted, bye bye 1971 cabinets. I was looking for a little inspiration and you nailed it, even down to having similar cabinets, colors, and the fact you've got it tied into a smart switch.

Great job! I am familiar with installing low voltage LEDs and you describe everything very well!

[@davesmith7057]

Great video for sure,,can the dimmer work if you have a switched outlet. Planning on changing out regular switch for dimmer and use the outlet to plug in tranformer,,thx

[@ProjectBilld]

So wiring a dimmer switch to a standard outlet is against code as you could technically plug things other than lights in to the outlet. However, there are special outlets/plugs made specifically for this. Search hdtr/ddtr outlets and rp-fdu plugs. You'd wire the dimmer switch to the lamp only side of the outlet and replace the plug end of the dimming power supply with the special plug.

[@davesmith7057]

I installed a dedicated outlet installed above cabinets just for driver to be hidden up there and feed wires down to calbinets,, Nothing else will be plugged in., thx for reply,,I think will be ok

[@davesmith7057]

Hi,,I have 9' of led tape and 40' of lead wires from driver,,armacost is saying at least 100w driver,,does that sound correct,,I was going to use 60w,,thx

[@ProjectBilld]

No that doesn't sound correct. 9ft of strip lighting isn't much. The lead wires don't effect the wattage required for the dimmer, only voltage drop. Wattage required should be calculated using only the length of the specific strip lights you are using

[@davesmith7057]

That's what I thought too,,thx,,I'm going with the charts recommendations for 9ft. I talked to 2 different people there and 2 different answers,,thx again

[@familymunoz2105]

Hi, could you tap into an existing ceiling light from a dimmable switch, meaning controlling ceiling lights and under cabinet lights from the same dimmable switch ? Thanks !

[@ProjectBilld]

I believe that should work. I could foresee the ceiling light and the led lights not dimming at the same rate being a potential problem but you won't know until you test it

Great video my friend!

[@ProjectBilld]

Thanks!

[@PrettyBoiFab1]

This is a great video! I’ve followed all the steps, got dimmable LED strips with the same light switch but mine aren’t dimming. Any ideas on what I may have done wrong?

[@ProjectBilld]

Is your driver dimmable too? I accidentally ordered a non dimming one the first time around

[@hbreardon]

Great video! Thanks so much for taking the time to do it so well! I have a design question: I have 3 separate cabinets and will have about 13' of lights total. The cabinets are fairly close together but the driver will be located about 17 feet away from the farthest cabinet. If I do home runs from each cabinet back to the driver I will use about 45 feet of LED cable. Just wondering what would be the best approach: 1) home runs or 2) connect them in series. Also wondering if I go with the 2nd option, should I create a loop and run back to the driver on the last cabinet?

[@ProjectBilld]

I think I follow. Since most of your distance is led lights and not wire, as long as you're under the max length of led strip for the specific leds you're using I think you'd be fine to do a straight run. It would definitely be less work that doing that than array or feedback loop configuration. Straight runs have a chance of getting dimmer at the far end but I don't think that's going to be a problem from what you've described

[@hbreardon]

@@ProjectBilld To clarify, the 45 feet would be the in wall 18/2 cable. Only 13 feet of lights. I would use much less cable if I wired the light segments in series. I'm thinking the kit at Armacost with the 30 watt driver and 16' of 2700K lights would hopefully work without any noticeable difference in brightness at the end of the run.

[@ProjectBilld]

Sounds like it should work as a straight run to me

[@hbreardon]

@@ProjectBilld Thanks so much. Appreciate you taking the time to help:)

[@DanNifong]

I would have preferred a switch with rave lighting, smoke machine and DJ air horn sound effects for my late night chef sessions, but this will work too I guess

[@Vikingchairman]

This video is great. Exactly what I needed. THANK YOU! When I bought the house my cabinets are already wired with halogen T10 bulbs that get really hot. I bought led replacement bulbs and then realized the power driver was AC so I need to buy what you used. Your link went to the 45 Watt but I should be able to get with by the 20 watt driver if its only for 5 1.5 watt bulbs right?

[@ProjectBilld]

You're welcome! Sounds like the 20 watt should be plenty

[@kevinhilton8683]

Cool install..anyway to modify this setup if you had wled strips that you could modify temperature? Would something like wled need to be incorporated?

[@ProjectBilld]

You'd need to use a compatible tunable white led driver. Something like this www.armacostlighting.com/products/proline-cct-led-light-control

[@travelwithoutfear.]

Hello question ? Exacly how u connect the driver to the dimmer switch

[@robertk8886]

Hello, I like this product. Since KZbin has changed its format, I find it difficult to get around it. Would you please tell me the name of this lighting system and where did you buy it. Thanks

[@ProjectBilld]

It's all linked in the video description. Should be located directly under the video but will need to expand it. Likely will say show more or something like that

[@TheJohnGray]

Love the video, question real quick for you, as opposed to an adding the dimmer to an existing three way switch, is it okay to add it an outlet we have below our cabinets? I’m assuming yes as it’s under constant power

[@ProjectBilld]

I can't speak to the electrical code in your area, but if there is constant power and adding the lights won't overload the circuit, then it should be fine

[@KPCKeysDIYBuild-Install-Fix]

Nice. I'm assuming one could daisy chain from end to end of the different LED strips if that were easier? I have total access down to studs. And you kept mentioning "LED cable". What wire are you using there, gauge and type?

[@ProjectBilld]

The wire should be linked in the video description. Don't see why you couldn't daisy chain the strips together, I pretty much did in a few places with short wires between strips

[@KPCKeysDIYBuild-Install-Fix]

@@ProjectBilld It is linked. I'm bad about looking in that description area and you did a great job with all of those links. Thanks.

[@DFinesse88]

would this be the same concept for running leds on kitchen island? thanks

[@ProjectBilld]

I don't know why it would be much different. You'd have to tell me more about your island and how you plan to use the lighting for me to give a definitive answer

[@JackOmen]

Might be a dumb question but how do you know whether the black was going on the negative screw and the red on the positive when you are installing it in the driver?

[@ProjectBilld]

The driver is marked and there's a hole/slot for each wire to go into. The screws clamp the wires into those slots. Does that make sense?

[@MedicalScyntist]

Best Video Ever ! 🙏

[@exportedafrican]

Are you able to put things in those upper cabinets or would they become visible when the lights are on? I have a similar setup but hope not to show all the stuff I store in there (thinking LED panels attached to the doors to block the visibility inside

[@ProjectBilld]

As long as the stuff inside the cabinet is an inch or two back from the door, I can't tell that anything is inside

[@GroovyMisfit]

How did you decide what LED manufacture to select for the LED strip lights and driver?

[@ProjectBilld]

I tried to find a dimmable driver I could hardwire first with good reviews and documentation and once I did I just went with the strip lights from the same company. Seemed to be good quality when installing and is still working well

[@sicilianbambino]

What was the color temp of the LEDs that you used ? Trying to decide to get tunable or fixed temperature. Thank you

[@ProjectBilld]

3k as that matches the overhead lights in my kitchen. I only really use the cabinet lights in the evenings so I wanted a warmer color temp

[@sicilianbambino]

@@ProjectBilld sorry one more. Where in the cabinet did you mount the light rails in the glass door cabinets on top? In the front or middle ? Were the rails 45 degree angled or straight across the top? Thank you again

[@ProjectBilld]

No worries! I did top, above the doors facing back straight towards the wall

[@EarlFestoon]

I assume the driver gets less that 120 VAC from the wall switch when the dimmer is deployed. Does this affect the voltage required to run the LEDs?

[@ProjectBilld]

I'm not sure, I never measured it while dimmed. I haven't noticed any issues with dimming them, though I do mostly keep them at full brightness since they're indirect lighting

[@bwilson5205]

Great video! If you were to use multi-colored LEDs, can you share which ones you would buy?

[@ProjectBilld]

Thanks! If I were going to do a hardwire setup like the video I'd likely use the same brand as the white leds I used. In addition to the driver you'd need to add a color controller as well

[@WalterMelons]

You could use the installation driver for this job with the offset head. Love that thing.

[@ProjectBilld]

Yes absolutely! Been waiting for it to go on sale

[@Av8er64]

This is probably the best install I’ve seen on KZbin. So I’m looking to do about a 50’ run of LED under cabinet lighting and I want to use a RGB smart variety. Any ideas? Most are fairly limited on run length.

[@ProjectBilld]

Thanks! I think that armacost makes a wifi rgb controller that you can use in place of the driver I used. You'd have to use a rdg led strip instead of the white one I did. Search for Armacost ProLine Multicolor RGB + White Wi-Fi LED Controller. Let me know if this helps!

[@johnmccormick2883]

Very well done video … the only unclear issue I was left with is how all your led strip locations were powered? Were they Daisy chained in series or paralleled back at the 45 watt power driver? In the video you show tightening a single set of led wires onto the driver output terminals but that was before you tackled the remaining locations. I would think that each location would’ve been freed from the drive by a separate cable? This would’ve resulted in three red and black cables at your driver?

[@ProjectBilld]

There's a short single wire going from the driver as only one would fit in the terminals on the driver. It immediately hooks up to 3 others. Each of those wires goes to a separate location

[@johnmccormick2883]

Thank you for the quick reply! I just watched the video again on my computer (big screen) and saw where you detailed the three runs coming back to the driver and wire-nutting them to the short piece of cable to allow it to terminate into the driver output. I have to commend you on your video and comment links ... it is by far the most thorough video on this that I've seen. I think you've motivated me to finally order some parts and start replacing my old fluorescent-tube undercabinet lights!

This is a cool video...howvever not having a tile backsplash in place already makes it easier. You can cover up all the work with the backsplace. If you have tile in place..best option is to use wireless LED's that work with Alexa.

[@ProjectBilld]

For sure! I experimented with running the wires without cutting holes as I know many people have existing backsplashes, even broke out an endoscope with a hook on it, but I couldn't get it to work. If the kitchen is against an interior wall, one could work from the other side but otherwise probably best to just go the route you suggested

The wire and led strips I linked are the exact ones I used. Both should be 2 wire. Just checked and it looks like the link is still correct and I didn't see anything on the product page about the led strip being 4 pin so I'm not sure why you're seeing something different

[@GoBucks1616]

@@ProjectBilld Thank you for the reply. I mistakenly bought a different LED tape that has 3 wires. White, with dimmer. I suspect that is why there are 3 wires and they recommend 4 pins if you cut/splice them. Your video was great. Wish all videos were as clean as yours.

[@bubbadubbzz7699]

Hi, I ordered everything in your list exactly lol. I have everything wired up, but it keeps tripping the breaker. Do you know what it could be? If I unhook the driver the kasa switch comes on and let’s me connect to it, but when the driver is wired up it keeps popping the breaker

[@ProjectBilld]

I'm not sure what exactly is going on that would be tripping the breaker but it does sound like the source of the problem is beyond the switch. How many outlets/lights are already on that circuit? Might be too much load with the new leds added. Have you wired the leds up yet? If so, try unhooking them from the driver and see if the breaker still trips

[@KPCKeysDIYBuild-Install-Fix]

If you shared a neutral across two different circuits, your AFCI breaker (if your electrical panel has them) might be what's actually tripping, not from overcurrent condition. When you go to reset, there's a pattern of light to look for. If you reset it and it was an arc fault then the light will glow for five seconds. If not arc fault but over current, there will be no light when you reset it. That's how my Siemens breakers work. Your brand may be a little different. To fix this, make sure you're not sharing neutrals across multiple circuits since there maybe multiple circuits in your box.

[@hamzapatel8139]

Can you use any dimmer switch? or does it have to be a specific one?

[@ProjectBilld]

You're welcome

[@stowerpower]

This is fantastic! Question: is it an option to do another connector on the end of the first LED strip you installed and run right off of that? Or does each LED strip need to go back to the driver like you did? Thanks!

[@ProjectBilld]

Yeah that's actually how some of mine are installed. Driver to led strip at the top of the cabinet then from that led strip down to the one at the bottom. That's fine to do as long as the length/# of leds doesn't lead to significant voltage drop

[@Jmags58]

Hey Bill, hopefully you see this. Do you have any idea about how long you can run LED strips until the voltage drop is significant?

[@ProjectBilld]

I put links in the video description under the planning section you can use to calculate that as it's dependent on a few things. You'd be specially looking for the voltage drop calculator. Let me know if you have any questions figuring it out

[@VictorCaoCA]

Can you run Romex directly into the LED driver without conduit? My city is pretty hardcore on code compliance.

[@ProjectBilld]

NEC (national electric code for the US) allows for romex to be run on the outside of walls where it not in danger of being damaged. Yes this is somewhat subjective but in the back of a cabinet is pretty safe. Can also depend on what inspector reviews your work if you decide to pull a permit for this work

Why not get the strip and diffuser installed before mounting the aluminum channel? Seems like it would save some contortions.

[@ProjectBilld]

If you used some kind of adhesive or the brackets that came with the channels to mount the aluminum channel you could probably do it this way. I drilled through the channels and mounted with screws as the brackets that came with them were terrible so the channels had to go up first

[@gotdamojo06]

I am thinking about doing this project on my new kitchen. Would I be able to power multiple power supplies from one single wall switch? I have 3 separate places that I have countertops and would like under cabinet lighting on all 3 sections. 4.5ft 4.5ft and 6.5ft

[@ProjectBilld]

Yes, with the power supply that I used, multiple of them can be connected to the same switch. But since you'll need to run a romex cable to each supply from the switch, why not just use 1 power supply and run cable to the less like I did across my kitchen?

@@ProjectBilld I was just going to ask this as we ran romex wiring from one switch years ago to 4 locations in anticipation of led install. Now time to install. Thanks again.

I dollowed the instructions and it worked but the light do not come on without the main light being on. Any suggestions?

[@ProjectBilld]

Impossible to tell without seeing it in person but it sounds like you wired it to the load side of the switch and not to a constant power source

[@MrDwayne220]

Well done!

[@ProjectBilld]

Thanks!

I have been looking to build custom LED strip light that is 0-100% dimmable and without PWM flicker when I point my camera at it just like yours seems to be. Can you tell more how to make it dimmable? I have existing house with existing wires in concrete wall so I can't easily add new cables for communication between light switch and LED power supply so I need solution that works with existing 2 wires like yours. What do I need to know to make it happen? I heard not every dimmer and every power supply work together like that. PS I am not in US so instead of giving specific brand names tell me what keywords to look for in specs. Is smart dimmer needed or if I don't need fancy features like timing, do dumb dimmers also work?

[@ProjectBilld]

A dumb dimmer should work. Look for one that's rated to be used with dimmable led bulbs, and look for a dimmable led power supply to pair with it

[@test-rj2vl]

Did you look for specific dimmer type? Like Phase-Cut Dimming, Pulse-Width Modulation, 0-10V Dimming, DALI (Digital Addressable Lighting Interface) Dimming or TRIAC Dimming? What are you currently using? Also do your dimming switches start making noise at low light levels or are they quiet?

[@ProjectBilld]

I did not, I don't know what the differences between those dimmer types. I just tested ahead of time before installing to make sure it worked as planned. I haven't noticed any noise from the switch

[@Float1ngG0at]

Pretty good video! Couldn’t you also run all the low voltage cables to one driver so you wouldn’t need to run power to all 3 drivers? And not need to buy all 3 drivers?

[@ProjectBilld]

That's how I did it in the video. I only used 1 driver

[@fabreezethefaintinggoat5484]

no insulate the unused ground wire?

[@ProjectBilld]

Ground wires don't need to be insulated, they don't carry any current (unless something has gone wrong of course)

[@bob4048]

Does the driver have to be in a junction box? I'm not sure of the code requirements.

[@ProjectBilld]

No, and it wouldn't fit anyway. It's double insulated, not really much different from a power brick.

[@bluesraincancun9217]

Thank you.

[@ProjectBilld]

You're welcome!

[@xskinyx]

hmm I know at least with automotive wiring - crimped connections are considered superior to soldered ones

[@ProjectBilld]

I believe thats because the vibrations from driving can break the solder joints over time. Hopefully that's not an issue in a kitchen lol

[@benblosser6739]

Just so you know… you could’ve used the dimmer switch that was already there by hooking up the load wire for the undercab leds to the load side of the switch and then reconnecting everything else the way it was instead of having to add another dimmer switch next to it

[@ProjectBilld]

The under cabinet lighting is on its own switch on purpose. If I used the existing it would come on whenever the overhead lights were on and I didn't want that. Plus you run into the lights potentially dimming at different rates if you share a switch

How about the web address for each part?? Thanks!
