Quantum T5 Fixture

SKU: QT5008

Quantum T5 fluorescent fixtures use 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.
