| | Re: SMD LED tape based light fixture
Bad News! This LED light has been in use, 8 hours a day for between 7 and 8 months now. I'm in the process of downsizing my aquarium set-up, so I have emptied the tank, cleaned it up for sale, and to improve my chance of selling it, will include this light. First, I measured the PAR it is now producing, and got 25 PAR at the tank bottom, less than 30 PAR 2 inches above the bottom. So, the intensity dropped from around 50 PAR to about half that in less than 8 months!
SMD LED strips, at least the cheaper ones, are clearly not going to last very long in this application. This is the last time I will use them. Back to Cree LEDs for me! Pay more, get more.
Curiously, my Finnex Planted Plus light has spent that same 7+ months as a desk light, on about 12 hours a day. It, too, is much dimmer now. It uses SMD LED's also.
