Wide Standard Aluminium Channel
Bought the Standard Wide Channels to house several runs of Phillps Hue Lightstrips. The Hue Lightstrips are roughly 15mm wide, so a standard LED channel (about 12mm wide) isn't sufficient; you need the 20mm bed of the Standard Wide Channel.
The channels themselves are of good quality; sturdy and well-finished. You won't cut yourself on sharp edges.
My only complaint is that the channel cover is described as opaque; but in reality it is closer to frosted. The Hue Lightstrips are about 1600 lumens, and even at very low settings the individual diodes are quite visible through the frosted cover. If you need a truly opaque cover (wherein individual LED diodes/hotspots are not visible), then this channel's cover is not for you.
I had planned to put a run of these under some over-desk cabinets, but in light of the cover's relative transparency, I didn't think that was wise, and mounted them on the back of the desk (reflecting light off the wall) instead.
