You get a 250w draw from the wall , and big savings on electric. I've used what is considered to be the best of breed components, quite simple the best of everything. You dont get better than that, and i will give a year parts and labour. The boards are populated with samsung lm561c s6 leds which are considered to be the top in the middle power class and will last for years, 50,000 hours. Other kits have miss matched cheap wire hangers that are not great and no adjustment..And ive now included 4 rope ratchets for full adjustments. And stainless steel eye bolts to hang your quantum light by. The wiring is neat and tidy in braided sleeving so it will last.
The boards feature my own dimmer box, so you dont need to mess about with the tiny screw drivers to dim the unit , they dim down to about 30%, with just a turn of the knob. You will get a mains lead 1.8 or 2m, 4 x rope ratchets, 2 x qb288 boards on a slab heatsink as you see in the pictures, its 63cm long and 19cm wide. There is a lot of wild claims about 4 qb288 matching a 1k hid lamp , but from the par readings ive taken at 18inches im not so sure, this gives 650umols in the centre of 1m sq and 300umols around the sides, you can always add more in the future, two in a 1m would be a kick ass light. The foot print is 2.5 ft x 2.5 or 3ft x 3 ft. Both kelvin ranges will do all stages of the growth 3500k gives slightly more leaf, than the 3000k.
