im not saying all will fail, but as a store we send em back all the time. i just sent a whole skid back of faulty ones, cap also makes a faulty co2 bunrer. the gen 1 and gen 2 are catching on fire and have burnt a few homes down already, i had to return 5 skids of htose recently. cap controlers is also r and m supply out of cali and they have gotten to big now and quality control went out the window on some items.
ive ran many bulbs myself and ill stick to the better customer service and quality of hortilux. ive also noticed my bulbs are lasting longer as far as colour loss goes as well. hortilux is also phillips and i feel they are the best in bulb tech in any size or type of bulbs.
