So was in contact with amazon after-sale about my light, parts are on their way... about 18 days til delivery. So from 250w down to 100 w grrrr! Hope this doesnt affect my plants and harvest too much!?! Will never buy cheap again! Only 2 yrs old and failing? Leds are guaranteed for 50,000 hrs? I’m not anywhere near that. Oh well... it is what it is
