Muzata 6Pack 3.3FT/1M White LED Channel with Spotless Lighting Effect Frosted Diffuser Cover,16mm Super Wide Aluminum Profile Track for Waterproof Strip Light Philips Hue Plus U103 HW,LU2 LP1 LN1 LW1

This product does what it says it will do. The led strips look way better now that they are inside of them, instead of leaving the strips bare

Perfect for my project. Easy to install. Look perfect.

Good

So I have an IP68 RGBW Strip that has 60 5050 leds/m 24v, so gets good a bright. You can still see "dots", but it is reduced as the depth of the profile leaves the LEDs recessed some. This likely means I also lose some of the angle (not sure how much, but I'd guess most of the light now goes out at maybe 90deg vs 120+ with a lower profile).

These are pretty decent light channels for the money. I did a ton of research, including watching THAT video on youtube. The one where he is testing all the diffusers and LED strips. I ended up getting the flat diffusers just because they will be very visible where I am installing and found the flat profile a bit of a cleaner look. The depth of the channel creates the "spotless" effect. But if you flip through the listing pics, you'll see it also depends on the light strip you get. Strips with widely spaced LEDs won't look as spotless as strips with more LEDS per inch or COB (continuous "neon" style). To make this project WAY easier, I completed each channel section BEFORE fitting them on the underside of my cabinets. Added the light tape, covers, caps etc. If you can do this, it will save you a huge headache. Cutting the channels for 90 degree turns is tricky if you don't have a ton of experience. I could have done them with my dremel, but opted to use a miter saw with a box to get the angle perfect. Cuts easy enough but you'll have to grind off the burrs to clean up the edges. You can buy the right angle pieces, but they only come in silver and IMO don't look nearly as clean since it adds an extra seam. My partner 3D printed some corner braces to snap inside the channels to help them light up easier. If you get black channels, use a sharpie to color the cut edges for a cleaner look. If you get white like I did, you can put a little white wood putty in the seam. This is done with picture framing and helps a lot. The diffuser covers cut easily with scissors and snap in just fine. Even if you have 90 degree corners, you don't need to cut the covers at 45 degrees. You can just cut them straight across and apply them perpendicular. I ran out of the end caps with holes, and had to improvise, so I think that Muzata should include a few extra. Maybe even one extra strip of the diffuser cover.
