Time-tested, proven results

With nearly 10 years of proven results, the ATI SunPower is used worldwide. When used with ATI T5 bulbs, produces significantly more light than most other equally-sized T5 fixtures.

Active cooling system

The active cooling system allows bulbs to run at more optimal temperature, improving both bulb output and bulb life.

98% reflective miro-silver

98% reflective miro-silver, bent parabolic reflectors direct the light where you need it most, on your corals.

Simple & safe to use

Insert T5 bulbs that best suit your needs and plug it in. Almost any ATI bulb combination will effectively grow coral. Since T5s are not a point-source of light like with LEDs, there's no need to worry about adjusting different color channels. The result is significantly less risk of burning corals.
Efficiency Chart

Comparable efficiency

While LEDs have a great reputation for efficiency, most people don't realize that tanks switching from LED to T5 use a comparable amount of power. The results speak for themselves.

Independent Control

The SunPower features independent lighting control. Two bulbs are wired on one power cord, with the remaining bulbs wired on a second power cord. This also allows for dawn/dusk simulation.
2 cords

Plug & play

Install bulbs. Apply power. Grow!


Even after factoring in the cost of switching bulbs once a year, the three year total cost is comparable to LED systems.
