Review on Muzata 10Pack 3.3FT/1M Black LED Channel System Spotless U Shape With Frosted Milky White Diffuser Cover 18X13 Mm Wide Aluminum Profile Track For Waterproof LED Strip, U103 1M BW, LN1 LU2 LP1 by Amrozi Papi

I bought some V-channel variants from the same manufacturer which I'm very happy with, and compared to this version, the brightness is significantly reduced and beam angle is terrible. Compared to bare LED strips, using this product reduces both brightness and beam angle by about 50% I'd say. The V-channel version was much better, maybe only a 20% reduction at most. Having the inner part of the segments in black I think is a big factor as regards brightness at least. Would be nice to have the outside black but inner walls white/silver.
