This is true and it works both ways. My big non sponsor light, when I got it, felt like it could be more solidly built. The bars and the way they insert didn’t seem solid enough. Well, this light has run continuously almost for close to three years now and never once have I had an issue with it. I wish I had tested it thoroughly and kept the numbers when I got it so I could compare to now. My understanding is that over time your diodes will lose power and the light will put out less overall.I can't tell you how many new bad new parts I've installed in my life Jon. It's not a build quality thing all the time. The shelf has it's darkness in the stockroom some days! Really throws a fuck into your mind when truing to fix something! Stuff breaks, I made my living relying on that! Sometimes it's brand spankin new broke!
