is that a difficult process from a technical perspective? have zero experience in electrical engineering
Nope, I dont think so, a little research on DIY cob lights and you can learn all you need to know. If you can solder wire, drill holes, and measure things accurately, you can do it. If you buy that Roleadro light, you can just switch the cobs for better ones and you're in a good shape for a great price. I'll show the process when I get my parts next week. Its easy, should take less than 30 minutes

I completed the upgrade to CLU048 1212 3000k 80cri cobs. They each have dedicated drivers running 36v at 1.2a, 88% driver efficiency. The unit came with 4 drivers, so 2 was removed. I removed one driver from each side and opposite ends so it would still balance. Removed old cobs and cleaned heatsink. I had to drill holes into the heatsinks for the bjb's, so I drilled a pilot then finished it with a 1/8th" bit. The aluminum was pretty firm, normally I used a smaller 7/64 bit. I secured the bjb's with 6-20 3/8" coarse thread screw with Arctic paste on the cobs. Then tinned the driver outputs and plugged them into their bjb. The top fits back on without any modifications. Better cobs, better spectrum, maintained active cooling, reduced wattage, and have 2 extra 36v/1.2a drivers to use on something else. The entire process took about an hour, mostly for drilling.P1300026.JPG P1300027.JPG P1300028.JPG

Visajoe1. - what is your total real watts on your modified light?
