The cooling fan's air passes through the area needing to be cooled. Has just enough power for 1-2 small to medium sized plants from seed to harvest. Works really well in my 3'x6' greenhouse.
Thumbs up. The timer is a must have. Fully adjustable brightness is great.
This is the second one i have purchased. Highly recommended for its price. No complaints definitely reccommend.
Stays super cool, and super bright. Compared the 1500w against some cheap double ended fixtures with gavita bulbs. Its quieter then my mini desk fan. And it runs fairly quiet.
King led has the lowest par rating of any brand on this list. They also have the lowest hour rating of all brands. They are also the least reliable brand during the duration of the warranty.
Barely puts out 200w with both switches on. Buyer beware- check the watts with a watt meter.
