I've been an avid grower for years, and within the past year and a half I switched from 600W HPS grows, to small scale LED grows.
For the past 18 months I have been using the Advanced LED Diamond Series 100 grow light with really good results.
However recently, I have been having issues with LEDs burning out and when one LED goes out in series, they all go out.
Advanced LED's was very nice in honoring their warranty and sent me a replacement and didn't even ask me to send back the broken one, so I decided to take apart the broken one and build me a new light using Cree's latest and most power COB led's the CXA3050!
The CXA3050 LED's put out over 5000 Lumens when driven at 1.4Amps and can get over 10,000 Lumens when driven at 2.5 Amps.
I ended up purchasing 2 LED's from digikey (CXA3050-0000-000N00W227F-ND). Digikey reports lumen output of 5683 at a color temperature of 2700K
According to the Cree data sheet, driving the LEDs at 1.5 amps gives about a 15% boost and has a forward voltage of 38V, so the lumens theoretically increase to 6535.45
Which comes out to approx 115 lumens per watt, which is as good as HPS (1000W HPS puts out 120,000 lumens = 120 lumens per watt).
OK, so with all the tech specs aside, lets put this thing to work.
