    Criticize my 2250W LED COB Build - CLU048 1212C4 3500k 80 CRI

    @Chronikool Im likely to put drivers on fixture, what do you think of this? I am guessing in my build I will likely need a minimum of 5-8, so it maybe worth thinking about I heard remote helps with heat, but do these drivers really output that much heat? It will be modular, not in a tent...

    CREE CXB - Why do the Better Bins have lower CRI?

    I am trying to understand the data sheets for COBS. To my knowledge the higher bins usually result in the cob having better CRI and higher lumen count. However the official cree spec sheet at cree seems to say otherwise. Better Bins are listed with Lower CRI (80), whilst the worse bins are...
