Invisible Wire LED Lighting: Ultimate Kitchen Upgrade!

[@oliverghuang]

Lighting design tip! Leave a gap between the start/end of the led strip and side wall, around 3". This will reduce the extra bright hotspot on the wall which helps direct visual focus to the countertop.

[@Peranolde]

Hey Michael! The main reason for the difference in language is that Transformers just transform the voltage output, whereas drivers convert alternating current to direct current. If you put AC power through LEDs you're going to have a bad time.

[@titosrevenger]

So it's basically an AC adapter?

[@scotteverard6286]

Transformers also come from another planet so they’re bound to speak a different language.

I loved the video, more people need to use this type of lighting on their furniture. I am a lighting designer and I have some points that I would like to complement and correct: COB LED strips are not very good for lighting use, only for decorative uses, especially when we are talking about a place that requires a little more luminous flux. They heat up a lot, which shortens their lifespan. The use of aluminum channels, in addition to providing a good finish, can help with heat dissipation, more people need to use those. To prevent the LED dots from appearing, the diffuser will be enough, in addition to giving a good diffused finish to the light. We just need to check the light retention. Another important point is the lumen. Watts is the power of the LED, not necessarily how much light it produces, some brands and models are more efficient than others. In summary, the main points you need to take into consideration are the CRI, as in the video it needs to be at least 90+, the lumens per length it produces, the light retention of the diffuser and a LED strip that has a low Steps value (MacAdam ellipse). I love these videos, in addition to being a lighting designer, I am also an interior designer, and I have already implemented several of your ideas in projects

So if you don’t recommend COB LEDs for under cabinet lights , and you don’t want light “dots”, what do you recommend?

[@sammyk9284]

@@karenmitchell6814that’s what a good diffuser will fix.

[@riakata]

COB LEDs are good for lighting they are just higher power output per foot which leads to more heat output. If you look at the specs a COB strip has way way more LEDs than a non-cob strip that is why it heats up more its just more LEDs in total. You lose a massive amount of light through diffusers even clear ones and closing a channel off insulates the strip a cob strip hidden properly in a channel does not need a diffuser. If you compare specs a COB LED strip can have much higher lumens per ft but does not need a diffuser which only lets 60-90% of the light through and that is converted into heat in the diffuser and traps the hot air above the strip in a channel. For any application where the strip is very close to the user you should use COB led strips to avoid the multi-shadow effect. They also high LED element failures better as there are more LEDs in total so one dead one doesn't cause a visible gap in the light.

[@metabeard3788]

I'm glad you went with the hard wired approach, rather than all of the battery, Wifi, Bluetooth crap that won't work in another decade. I did mine this way as well and wish I'd installed the transformer remotely and ran the low voltage wire like you did. Instead, I hid my transformer within the cabinets, which was a massive pain in the ass. Looks great and works nonetheless, so live and learn.

[@rjrotermund]

Thank you!!!!! Best most practical, straight forward and clearly explained video on LED lighting in woodworking on KZbin!!!!!!

[@That_Ryan_Guy]

When installing the wire in the walls use a "speaker" wall plate with binding posts. This not only gives a cleaner & more professional appearance but also saves from having to locate the wire. Furthermore instead of running a wire between cabinets you can tie into one location. As a bonus you can use the multi binding post option for "zones", like below cabinet and above cabinet lighting. You can also use the multi option for additional drivers if you require more power than whats available with one driver.

[@2hlix]

Also in same vein. In wall approved speaker wire is often a large enough gauge for lighting. Unlike this video I wouldn't trust door bell wire for lighting applications as it's too small for the possible currents imo.

[@That_Ryan_Guy]

@@2hlix Speaker wire is a awesome idea! Especially if you need to run it a longer distance or significant load.

[@joegibes]

​​​@@2hlix18 AWG is likely totally fine for LEDs like this, but it does depend on the current and length of run. Ex. For 5A, 18 AWG should be fine depending on the length. If these LEDs are 14W/m at 12V, that's 1.17A/m. Rough estimate of 3 meters means the LEDs from the video draw 3.5A. Since 18 AWG is rated for 7~10A (depending on many factors), it seems appropriate for the lengths in this video. Even 20 AWG might be fine, but it depends mainly on the cable's ambient temp, heat dissipation, and length to avoid too much voltage drop. Also depends if you need the LEDs at max brightness all the time (which can degrade over time - ideally, go for brighter than you need), both for the general heat produced by the cable, and if any voltage drop from the cable length will be noticeable. Also note that the conductors within the strip itself are likely much smaller area than 16 or 18AWG wire... Which is one of the reasons why you need power injection for longer LED strip runs.

[@apostolakisl]

Nice work, but I have to ask, if you built the cabinets, why didn't you build the valence into the original cabinet design? I also found that putting the light strip all the way to the front, directly behind the valence front blocks light from reaching the front edge of the counter. I mounted my lights about 2 inches from the front edge which resulted in the light nicely illuminating the entire counter from the very back edge to the front edge.

[@helvettefaensatan]

This was my main take-back from this video, that having overhang in the cabinets would be so much better.

[@MegaDuncz]

Electrical Engineer here, the reason it is called a driver rather than a transformer is that a transformer is explicitly a device that converts AC power to a different voltage of AC power. LED are diodes and produce light when power is fed through them in one direction, thus the AC power will need to be transformed down to 24V and then passed through a rectifier to turn it into smooth DC power that is suitable to drive the LEDs

[@112Haribo]

thats kinda BS, since that would mean all laptop chargers would be called 'drivers' as well. It's mainly called a 'LED driver' because it's a device that... drives LEDs.

[@AdamsLab]

First off, thank you for using channel! So many people (including "professionals") don't do this, they just stick the strip directly to the underside of the cabinet 🤢 Second, you spoke to making sure the driver had enough wattage 👍but the other thing that's important to consider is voltage drop. LEDs are typically constant current driven, but these strips are typically constant voltage driven, so making sure they have the correct voltage is important, otherwise they will not get as bright as they should, produce the color they should, or may fade along the length of the strip (basically the LEDs at the start of the strip get enough voltage but they ones at the end don't). When I did my kitchen under cabinet lights, I placed the driver, as well as smart controller in the cabinet above the fridge. I then ran three separate cable runs to each cabinet via the attic. (My setup was complicated by the fact that I used RGBW LED strips, so I had to use cable that had 5 conductors in it). In any case, after going from the cabinet, into and across the attic, and then down the wall into the cabinet, even the shortest run was a few feet. The longest was probably more than 10'. I had to estimate the length and calculate the estimated voltage drop to make sure that each strip was seeing 24v both at the beginning and end of the strip. Realistically, if you're getting a little less (want to stay under 3% drop based on the NEC) voltage at the strip it's probably ok, as long as it's the same along the entire strip (especially for long strips) and it's not so much of a drop on one strip vs. another that you notice a brightness difference. To compensate for a long run you can increase the wire gauge, or move the driver closer (i.e. make the run shorter) if possible. If the strip is particularly long you may need to run a second power cable to it and tap it either in the middle of the strip, or at the end. To calculate voltage drop, you can Google "voltage drop calculator," and plug in the estimated length of the circuit, wattage, and voltage, and the gauge of the wire you plan to use. Just make sure you switch it to DC.

[@mvadu]

You can also connect both ends of the power rail to the driver, that way you almost avoid the drops.

Thanks for sharing this, always love the attention to detail you put in your projects. Some people had some great comments already on the importance of CRI, color temperature, etc. This may not be a detail that many of your customers use but I've wired a lot of my furniture/in wall lighting with 6 conductor wire just so I have the option of going full RGB CCT in the future. Wire is inexpensive and who knows what one might want to change to 5-10 years down the road. Keep up the good work.

[@pfurrie]

Michael, first-rate vid and appreciate your attention to detail. However, you did leave out one aspect I've been trying to get answered for my project: what level of light do you need over the counters? Here are some other questions I had while watching: - What gauge wire did you use to interconnect your LED strips between one-another? - Is your LED strip setup dimmable? - Are the strips a fixed color temperature? - With the COB LEDs, could you have gone with a clear channel cover instead of frosted in order to have less light loss? The COBs have a diffusive layer above the actual LEDs. Thanks, and this video got me to subscribe to the channel.

[@harvey66616]

Would love to see a reply from Michael with the specifics, but in the meantime... -- I don't know what wire gauge he used, but for low-voltage stuff, you almost never will need bigger than 18 AWG. It does depend on just how much lighting you're trying to run off the same wire, but most of the time you'll run into aesthetic issues related to voltage drop before you overload the wiring and will want to upgrade the wiring size for that reason anyway. In practice, 20 or 22 AWG is usually fine. There are online calculators you can use to be sure though. Take your amperage, add 25% (for constant load situations, all wiring and equipment should be sized so that you're only using 80% of the rated load), and see what gauge wire is required. -- The driver he took from his shop lighting is dimmable. You can tell either by looking up the make/model # online (pulled from the closeup shot he provides of the driver), or just noticing at the end when he's testing the lights, that he goes through a dimming range of the lights. -- The LED strips used here have a single color temp. Of course, if you want to get fancy you can use temp adjustable LEDs, or even RGB, but those would require a more complicated wiring setup, as well as a different kind of light switch, or at least a remote control tied into the system somehow. -- I wonder about the diffuser myself. Honestly, with the COB strip, I probably wouldn't have even bothered with the diffuser. It's just going to keep airflow away from the strip, which likely will shorten the life of the strip, and the COB style LEDs already have very even light. That said, my own preference might not be relevant, since I wouldn't use the COB strip in the first place. For my own kitchen, I used regular strips with 2832 LEDs, relying on higher density spacing (120/m) and a diffuser to even out the light. In a previous very-low-budget install, I was just using strips with 60/m spacing and no channel or diffuser, and even there I rarely noticed any unevenness of the light; occasionally I'd catch a glimpse of the individual LEDs reflecting from the toaster or microwave, but the illumination of tasks was still great. With the 120/m and a diffuser, you can only notice the individual LEDs if looking directly at the light strip, and of course since it's carefully installed under the cabinets where you're not able to see the lights directly, this is completely fine.

[@benene055]

awesome tutorial! If I had the tools, I could easily do it on my own just by following your video step by step.

[@joegibes]

You can put up LED strips with very minimal tools! Just get the aluminum channels, they come with diffusers and screws. If your cabinets already have a lip at the bottom, just fasten em there! And you don't even need any soldering! You can just use lever nuts, crimp connectors, the included barrel jacks (if compatible), solderless splice connectors, etc... and if you need to cut a strip and add wires between, you can probably buy connectors meant for that style of strip that just push on the ends. This is where a very small amount of soldering skill can be convenient, so you aren't relying on these push-on connectors and can totally customize your wire length, but you don't technically need to.

[@CamiloSperberg]

The big plus of aluminium channels is that they increase the dissipation area so your LEDs will be able to dissipate heat faster making them last longer. Besides, you can install diffusers which will help with non-COB LEDs.

[@DanielRichards644]

A quick note I would make about Color Temperature (as a LOT of people have no idea about this and just randomly grab LED bulbs (can't tell you how many 4000-5000k LED bulbs i've seen in living spaces in houses), the typical Incandescent bulb is a 2700k color temp, some people may find 3000k a little "harsh", I know I did when I bought them but I lived with it because the bulbs I got where so cheap they paid for themselves in a couple months and this was from 10 years ago when the average LED Bulb was $5 or more. So people upgrading from standard bulbs in a residential setting I would advise 2700k for all your bulbs.

[@glittalogik]

When my partner and I go for evening walks around the neighbourhood, we often have a super judgey running commentary going about the houses we pass - all good-natured of course, and wildly hypocritical given the current state of our own place 😅 It's equal parts gathering inspo for future upgrades and just poking fun at questionable design/decor choices, but one thing that always catches my eye is cold-ass lighting, especially in apartment blocks where there's always one glaring blue-white apartment sticking out like a sore thumb. I saw a house last week that's seared into both my memory and my retinas. It had a huge living room fronted with glass sliding doors so we could see straight in, it was utterly bare (white walls and white tiled floor) apart from a coffee table between two very expensive-looking black leather chesterfield sofas, and the lighting was bright and cold enough to put an Intel R&D laboratory to shame. Like, who the hell is relaxing and feeling at home in that space? I'd be sitting on one of those sofas, doing nothing, with the stress levels of an animal being hunted for sport 😬

[@joegibes]

​@@glittalogik Brands selling "daylight" bulbs as "pure, clean, and energizing" should not be allowed lol. Maybe fine for task areas, but even then I'd recommend 3500~4500k as a more "neutral" white. Too bad it's hard to find bulbs that aren't either 2700K or 5000K/6500K... And don't get me started on tint, lol. Daylight bulbs (especially 6500k) are just not pleasant indoors at night! Also, Philips sells "Warm Glow" dimmable LED bulbs that go from 2700K to 2200K as you dim, for a VERY pleasant cozy glow as they get dimmer!

[@joegibes]

Btw, my recommendation for the most pleasing, non-green no-flicker LED bulb with great color rendering: the GR Reveal HD+. Widely available (Lowe's, Target, Online, etc), not super expensive, and they're just really nice. 2850K but not harsh at all. Compare to whatever LED bulb came with your house, and it makes those looks sickly green - if anything, these are a bit "rosy" due to the special glass/coating. They're also full frosted glass bulbs, just like the old incandescent, rather than plastic half-globes. Another good recommendation is the IKEA TRADFRI smart bulbs! Surprisingly good color rendering for the price, and they're widely supported.

[@willsalz]

‘Transformers’ transform AC voltages to other AC voltages. LEDs need DC current, so an LED driver needs to convert AC to DC. A driver [ probably ] actually has a transformer inside to step down mains voltage, a rectifier to convert AC to DC and then maybe some other power electronics to produce a clean DC constant current source.

[@Greech-Grimwater]

@@aleksastojanov4033 Actually, you are incorrect. While you can get a standard 24v brick for cheap, when you want to use a house dimmer switch, you need a "magnetic" dimmer to be able to dim the lights. The dimmer that normally would dim 120v. The magnetic driver can compensate for the 120v dimming and relate that to teh low-voltage side. Finally, while $100 is a lot, about the cheapest I found was $60 (for a reliable one). Look for a brand called Inexaccessories (B0CP7D89YW). I just got it and it seems to work well.

Transformers are passive devices, kind of like a gear reduction but for electricity. The output is proportional to the input. Furthermore, they only work with AC voltage. Drivers will accommodate for variations in input and regulate the output as a pwm DC output more like a governor, outputting the specified signal regardless of the input (within a specified range). Fancy drivers will let you control the brightness and color by modifying that pwm output, presuming those features are supported by the strip.

There is another major problem with LED lights that I’ve noticed more and more lately especially with strips like these but also cheap bulbs. Many often have insufficient UV filtering! With some it’s so bad that you will get a slight backlight effect at dim settings! However, most can’t be seen but cause a much bigger problem, bleaching. You’ll first notice the plastic diffuser turn yellow or orangish over the space of several months to a few years. In some cases items near the light will also start to bleach as if left out in the sun! I would love to find a reviewer that can measure for this somehow. Being confident that a LED strip won’t yellow over time or bleach your work area would be incredibly helpful.

FYI: When going from AC to DC, voltage is rectified. From DC to AC it is inverted. Transformers increase or decrease AC voltage. Since LEDs will burn themselves out, a driver is used limit current and voltage.

Since all of the base cabinets along a side are already connected, and this is low voltage wiring, another approach could be to run the low voltage wires from behind the uppers down to the bases before drywall is installed (or cut holes and fish same after drywall is installed) and then have a chase between the base cabinets along the back near the countertop so that you can then connect all the low voltage wires together. One of the base cabinets can then have an outlet where the driver can be placed, making it more convenient to replace when it ultimately fails.

Looks great! There are lots of ways to install LED lighting, but if you're building the cabinets already, might as well keep the wires hidden as much as you can. FWIW, matching color temps is a safe way to go, but I have found it's not strictly needed and there are reasons to not. After testing with some samples (make up a short run, powered by a battery...LEDs are so nice to work with :) ) when I added LED cabinet lighting to my kitchen, I discovered a couple of things: 1) For task lighting, I much prefer 4000K. Yeah, the room lights (can and pendant) are "warm white" (which is usually 2700K, and is in my case, but I've seen some manufacturers claim "warm white" for even warmer color temps), but the undercabinet lights are all indirect and largely take on the color of whatever they're lighting up. More important though, the cooler temp helps my aging eyes when actually working on the counter with food prep and whatnot. Even with a high CRI, 2700K just doesn't give as much contrast and detail as 4000K. 2) Related to that, I also installed lights inside the cabinets at the top, where the doors have glass and the space is used for decorative stuff (vases, jars, etc.). Even there, though it's not task lighting, I found 4000K works better for me. The cabinets are all wood (mostly maple veneer), and that has the effect of shifting the glow down to warmer color temp anyway, but the decorative stuff "pops" better with the cooler temp light. I love the way the warm glow from the wood, around a well-lit glass vase, looks in the cabinet. Of course, YMMV. Just wanted to emphasize that with color temps, as with many aesthetic choices, one size does not necessarily fit all. It can not just be okay, but even preferable in some situations to _not_ match the color temp with the existing lighting.

The lights came out great. How tall are your upper cabinets? How much clearance do you have between the upper cabinets and the counter top?

[@MichaelAlm]

Thanks! 19” from the countertops to the cabinets.

Any consideration for just using analogue LEDs in this scenario than digital LEDs?

When cutting the miters at 3:30, any reason you're changing the angle on your miter saw instead of just flipping the other workpieces over to the right side of the saw? Assuming the miter saw fence is straight you'd get your complimentary angles without the chance of small mismatches in the angle, it would also be faster.

[@rkalle66]

You may just drill the hole for wiring through the aluminium diffuser as well to pass the wire through. Once the strip is glued to the aluminium you cannot access the screws holding the diffuser anyway.

@11:25 Transformers in electricity means a physical thing - a block of metal with windings. LED drivers might have a coil, but not a transformer, because they're switching regulators.

[@stiansberg7869]

Great video. My kitchen lighting as bad. Might have to try an upgrade after watching this. What is your reason for going for the full stove vs separate cook top and oven? (not sure what you call it in english). Personal preferanse or is this just the most normal where you live?

[@MichaelAlm]

Thanks! Glad the video was helpful. I picked out the oven stove combo partly because it’s what I’m used to, but also because I was having trouble figuring out a good place for a cabinet oven. They look cleaner, but with this size kitchen it would’ve been a less efficient use of space.

[@christopherkohl4930]

Is that an induction range? If so do you like it?

[@rotteneffekt4416]

Awesome. One thing though, you put screws under the valances for 'maintenance', but soldered the LEDs to the wire.

[@MichaelAlm]

De-soldering is pretty easy. I know because I had to do it a couple times 😂

[@marcelimarilag]

For future servicing I thought it's better to just use wago lever nuts instead of soldering. There are also low voltage wago nuts for cheaper option.

[@robertberger8642]

Great lesson, thanks!!

[@DarellCraighead]

How would you handle 90 degree turns either above or below cabinets?

[@biedawo]

Did you consider using Wago connectors?

[@MichaelAlm]

I’ve had mixed results with those. Some people love them though

[@biedawo]

@@MichaelAlm - what issue were you having with them? I was thinking these would be good for making the connection within the valence between the main wiring and the pigtails going to the strip on the valence. This would seem to be more serviceable (?). I solder a lot for electronics, but soldering in a cabinet is... no fun. That kitchen is turning out fantastic, btw.

[@harvey66616]

@@biedawo I can't speak for Michael, of course. But I've done a similar project in my own kitchen, and found the Wago connectors invaluable. I didn't hide my wiring with the build valence as here, but my cabinets hide the wires pretty well as they are. Wago's inline connectors are key though. If I were to use their traditional "all the wires come into the same side" connectors, it would be a lot harder to keep the wires running flush inside the corners of the cabinet undersides. That said, I used the regular ones anywhere I didn't need to hide wires, e.g. where the drivers are plugged in out of sight. I did a similar project for toe-kick lighting and for that I didn't have the Wagos yet and soldered the connections at the cabinet. It was doable, but it'll be a pain if/when the strips need replacing.

Without getting into the weeds: transformers are usually AC-AC where as drivers (or power supplies) do AC to DC. Good ones will prevent any flicker as well.

[@efrainviscarolasaga2158]

Question, I'm retrofitting some old lights under my cabinets and they are these little glass bulbs on a runner that get super hot and I can't find replacements for them. Anyway, they are all hard wired and connected to a single switch. If I connect the driver to the switch to power the first strip, can I use the existing hard wiring to conned the LEDs from cabinet to cabinet? Does that make sense. Basically it's hard wired as a full power circuit, but if I step down w the driver, do I have to replace the wiring down the line.

[@GARRY3754]

Thanks for brain food. I must ask which miter saw besides Festool is set up for dust extractors? I have older DeWalt 12” slider and it’s hit and miss. Thanks

[@mrljvb]

A transformer transforms voltage, but it remains the same with regards to type. So using just a transformer will convert an AC signal (does not work with DC signals) to a lower or higher AC signal. For a DC signal, you need a rectifier, which is essentially what a power supply is. LEDs run on DC, no AC. Additionally, since you are using 24V, you do not have to worry about a voltage drop as much as you would with 5 or 12V LED strips. If you are doing long runs, or the led strip is far from the controller and power supply, the voltage drop will cause the end of the led strip to be dimmer than the start. You can inject power at the end, or middle of the led strip to compensate for that. Or just use 24V.

[@Paradigm1976]

Is the valence front overhang beyond the door just an esthetic element, or does it make the LED strip lighting more useful?

[@boriss.861]

LED Drivers are called Drivers due to Constant Current Regulation as an LED is a Light Emitting Diode, diodes only allow voltage in one direction.

[@NicholasSandar]

Did you consider using threaded inserts + machine screws to attach the valences to the bottom of the cabinets? I'm more of an electronics guy than a woodworker, but I've found that those are a little more robust to being repeatedly disassembled/reassembled.

[@MichaelAlm]

Threaded inserts would be an upgrade for sure, but I don't think they will be removed often enough to strip out the screw threads.

It comes with the Milwaukee M18 palm router. Works really well!

[@js71378]

Any reason you didn't go with diagonal (45 degree) aluminum channels? I'm currently planning my install and also planning on putting the LED strip at the front of the (underside) of the cabinet. 45 degree feels like it makes the most sense... but maybe I'm over-thinking this?

[@ettilapse]

did you go with it? curious to the results. I've considered 45s for a while but never went for it.

Now show that for existing cabinets. 😄
