Quantum T5 4' 16 Bulb Fixture, 864w

PLEASE NOTE - the Quantum T5 fixture color will be changing to white in December 2014. During the transition you might receive a white fixture before the photo on the website is changed. Product performance and features have not changed, the only change is the color.

Quantum T5 fluorescent fixtures use Fulham high efficiency, active electronic ballasts to power the high output, 54 watt, 4 foot T5 lamps. The Quantum T5 features a shallow profile, very low heat, wider bulb spread, and 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, and 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 and still achieving a wider coverage area. The large area of light dispersal coupled with the intense light is what makes Quantum's T5 optimal for your garden's growth.

Customer Reviews

Mostly good! Review by mr. fancy
- You will need a drill and nice sized table to put this on if your floors aren’t tidy. This thing is f'ing huge & has many important little screws.

- The instructions make sense for the most part, and there is a video demo for set up on youtube. It is critical to remember to remove the plastic film from the lamp shades before assembling. The instructions do NOT tell you to rotate the bulbs to “9 & 3” until they click in. This is important to draw power to the bulbs.

This fit in my 4x4 Gorilla Grow tent just fine, and 2 weeks into my first grow I haven’t had any trouble. I am looking forward to using this solely as a veg light in the future. In the future I would buy a used lamp & fixture (possibly even 2 smaller ones), and spend the difference on more new bulbs.
