Hey bud, if your in the U.S. check out @BigSm0 and his autocobs. Awesome light, great price. I just picked up my 3rd last week. I saw the difference immediately. Check him out in the cobshop if you haven't. I was using a dimmable 300w led, it worked but night and day difference.
If I had the budget id only have cob light but right now I dont , I dont mind paying 70$ for a 300w led atm they seems to work fine. In the future , that is for sure and nah not in the us
