The media could not be loaded. The v-channels are uniform and consistent dimensionally. Available in several lengths and finishes. The slots for the plastic fogged covers and the covers themselves are consistent as well. The plastic covers are quite difficult to snap into the channel though. They need to be pressed into the top of the channel but not slid into the slots on the channel. I found that once the channels and corner pieces were fitted to the mounting clips with the LED strips securely adhered, it helped with the 6 ft long sections to apply crosswise short strips of blue tape to initially line the covers up along one edge of the channel. Then starting at one end press along the edges and work towards the other end exerting enough pressure as you slide your thumb along until you can hear the cover snap in as you go along as you remove the tape .It can be pretty tiresome if you are working with your arms above your head along the edge of the ceiling. (Which I did for a full 48 feet of cover) . I practiced with a short piece of channel and a fogged plastic cover in my lap until I was able to hear the distinctive sound it makes as it snaps into place. It was well worth the effort as the results of the uniform slightly neon look was what I was looking at as opposed to bare exported LED lights.

Used these for some under-cabinet task lighting in the kitchen, and installed with 5630 warm white led strips, a dimmable NON-PWM driver (search "HitLights Driver"), and a home depot dimmer switch that works with LEDs.

I planned out my install, cut the rails and lenses to the right sizes, hardwired the dimmer in the wall and drivers under the cabinets, adhered the pre-wired strips to the rails, connected them to power, bench-tested the entire assembly, and finally clicked everything into place. The final installation came out better than I expected, and the diffuser lenses are great. When the lights are at full brightness, I don't see the individual LEDs in the reflection of my quartz countertop or my appliances and containers that are sitting there. It looks like a clean and even bar of light, getting rid of all the shadows that the ceiling fixtures couldn't illuminate.

A few tips come to mind that will hopefully make your project go smoothly:

1] PLAN, PLAN, PLAN before you start, and reassess if you need to for tricky spots like turns, and passing through sections of cabinets. Get a good idea of how to make what you envisioned into a reality, and get creative with solutions to unforeseen challenges.

2] The screws provided that are for the mounting clips are very small, and very brittle. If you're going to install them into a hard wood (such as quality cabinets), I highly recommend pre-drilling the holes to a size only 1/64th of an inch smaller than the screw, soap the threads (rub them on a solid bar of soap to lubricate the threads of the screw and facilitate insertion), and do not use a power tool to sink them. I got advice from a buddy who bought the same set before me that having an extra pack of hardware would help, so I bought another bag of hardware, and I found that it was worth every penny.

3] The diffusers and rails can be cut to size fairly easily, but take your time! I rushed with the hacksaw on one of the rails, and when it was time to install the diffuser lens, I couldn't get it to snap into place. After inspecting the rail, I noticed that the diffuser guides were chewed up from sawing too quickly, so I used the tip of a flat screwdriver to open them back up.

Do it right the first time, or you'll be doing it again. Good luck!

The media could not be loaded. Learned quickly that when installing, put one support about a 2 feet in and the next one at the very end so you can snap the current and next price into a single bracket. This will give you the most even and seemless appearance and requires minimal measurements and compensates for an uneven ceiling edge.

Love these and am going to switch up my external lights to these channels next summer. Easy to install, great visibility, when installed correctly, you can just unroll the lights.

The quality seemed good, they were straight and the covers fit in nicely. The mounts are nice and seemed secure and easy to attach. I had two concerns though. I wanted to hide the wiring so I drilled a hole on the back of the aluminum channel and ran 22 ga 4 wire ribbon through it. The wire barely fit and I would think that this size would be typical of LED wiring. Since the wiring came from behind the end cap won't fit on. There is a triangular piece that goes in to the channel the wiring is running through. I imagine I can modify it to make the cap work, but I haven't had a chance to do that yet. There is a hole in half of the end caps, presumably for the wiring to go through. I think the hole would have been a little small for the ribbon cable too, but would probably work if the ribbon was folded in half. Over all it seems to be a good product and I would recommend it to others.

I've been using these for LED light strips I install in custom cabinetry and built-in units. These work great, they allow the LED adhesive to cleanly stick to the aluminum surface (so far without letting go). The diffusion covers are great to allow the light to spread a little more evenly too.

The only downside I have for these are the installation clips. They are tiny little screws and are hard to deal with. Also, the clip protrudes down further than you would think making it potentially visible from the front of a unit if you don't recess that area deep enough. So on my most recent installation I decided to not use the little clips and instead I drilled directly through these brackets and screwed them to the wood that way. Worked great!
