The ATI Dimmable SunPower T5 High-Output Fixture is the latest evolution in T5 technology adding full, integrated dimming control to the proven performance of the original SunPower. Compared to other lighting systems with dimming control, the ATI Dimmable SunPower offers an unmatched combination of output and control at an affordable price-point.

SUPERIOR LIGHTING CONTROL: With 10 individual set-points, the built-in controller produces much more realistic dawn-dusk and daylight simula- tions than non-dimmable fixtures.

PLUG & PLAY: With the built-in controller there is nothing more to buy.

UNBEATABLE PERFORMANCE: Superior design and high-end components produce 50% more light than most other equally-sized T5 fixtures. An active cooling system allows bulbs to run at a more optimal temperature, improving both bulb output and bulb life.

ENERGY EFFICIENT: Produces up to 50% more light than most other equally sized T5 fixtures, without using more energy.

CLEAN, CONTEMPORARY DESIGN: The slim, silver colored body is light- weight, durable, rust-proof and just 2.1” high. All components including the controller and T5 ballasts are built into the fixture housing with the only item external to the fixture being a single power-cord.

QUIET, COOL OPERATION: Runs cool and produces virtually no noise.

    It works extremely well. Switching from LEDs to this was a night and day difference. Highly recommend, the build quality is very good (single bulb reflectors, cooling etc.)
