Quantum T5 fluorescent fixtures use high efficiency, active electronic ballasts to power the high output, 54W, 4 foot T5 lamps. The Quantum T5 features a shallow profile, very low heat, wider bulb spread, & high quality German glass coated aluminum reflectors. Engineered with broader angles, these reflectors allow more light from the backside of the bulb to make it to the plants, & penetrate deeper into the canopy without being obstructed by the bulb itself! this "house of mirrors" effect lets you place the Quantum T5 closer to the tops of the plants, delivering 28% more lumens & still achieving a wider coverage area. The large area of light distribution coupled with the intense light is what makes Quantum T5 optimal for your garden's growth. Assembly required (see instructions). 28% more lumens at plant level 60% on average lower shipping cost 30% more efficient than comparable models increases the efficiency of any T5/Ho 54W lamps high quality German glass coated aluminum reflectors patented folding design for easy storage & transportation designed for Quantum T5 lamps, but will light any manufacturer's lamps 120/240V smartv out of the box (120V cord included, 240v-bacd6 cord optional) lamps not included

Bought 3 of these 6 months ago and haven't had an issue yet
Great light. Little tight to fit 2 in a 4x4 area. Not sure it was worth the extra $ then a regular t5, but it was the only t5 in stock that I could order that would fit in my 2x4 and then 2 in the 4x4. They do put out some heat so expect to use an ac in summer.
I've had this now for about 2 weeks, and so far all is good. The plants love it and this will be easier on the electric bill vs a 600 watt HPS. This also helps reduce heat associated with HPS and MH. It was easy to put together and seems to be a good quality product.

I did not know it didn’t come with bulbs. But I ordered 2 of them and both boxes came in pretty rough shape. One of the light fixtures did have some damage and when I was assembling them one of the screw heads snapped off.
I received my fixture and set everything up, bought brand new bulbs for it and put everything together and all the bulbs in place and when plugged in it does not work at all, none of the bulbs will fire up and I tried swapping the bulbs for different ones that were currently working in a separate fixture and they do not work either. So I spent all the money on this and it does not work at all, so upset about this because I needed the light and it took almost 3 weeks maybe 4 to get to me. Anyone have this issue and know how to fix it? If I can get it working I'll bring my rating back up but until then this is useless... It looks nice but aside from that I am not satisfied...
Comes all folded up and takes more than 20 screws to put it together. Non brand name ballast. Not a commercial quality light, the frame is floppy. It has two on/off switches so you can select which bulbs you want on.
My order arrived within 2 days on time and undamaged. The Quantum T5 was very easy to assemble,it took less than 15 minutes. This unit puts our very little heat,my plants are loving it and so am I. I'm glad I ordered it. Thanks again. Sincerely, Keith M
