Time-Tested Proven Results + Control
Time-tested, proven results
The ATI Dimmable SunPower has been delivering proven results worldwide for more than five years. We recommend using ATI T5 bulbs in your fixture, which will help you produce significantly more light than most other T5 fixtures of the same size.
Active cooling system
Bulb life and bulb output are improved with our active cooling system to keep your bulbs at a more optimal operating temperature.
98% reflective miro-silver
Direct the light where your corals need it most with the 98% reflective miro-silver bent parabolic reflectors.
Simple & safe to use
Pick the T5 bulbs that are best for your needs, insert them, and plug in your fixture. ATI bulbs work in almost any combination to effectively grow corals, and since they're not a point-source of light like LEDs, you don't need to worry about adjusting different color channels, meaning there's less risk of burning your corals.
With 10 individual set-points, the built-in controller produces much more realistic dawn-dusk and daylight simulations than non-dimmable fixtures. The controller automatically adjusts from one set point to the next making programming a breeze and eliminating any intensity jumps.
Our results speak for themselves. LEDs may have a great reputation for efficiency, but our T5 fixtures use a comparable amount of power. Make the switch with confidence.
Plug & play
Install bulbs. Apply power. Grow!
Fans are temperature controlled which typically results in a slower fan speed and less noise.
