I'm using it right now and for veg growth it works great, some of the tightest plants I've grown and significantly more bud sights.( haven't flowered with it yet.) it is quality gear, well put together, great heat sink. I got it for $319.00 from sun flower supplies out of new york, They shipped it that day. and it arrived promptly. They raised the price to $345.00 but it is still lower than anywhere else. Anyways the coverage is more like a solid 2x2 and the best growth occurs at 1 foot above plants. This light was designed and made in cali(thats what I liked best, most of the other leds are made in china.) I think its a mix of 5watt and 3watt leds its either that or just 3watt. Good product for the price
