T5 Fixtures

A T5 HO fixture supports coral and plant growth and creates even light throughout the tank, unlike LED. The thinner T5 bulb is often combined with individual reflectors to focus and spread light into the tank, increasing efficiency. A T5HO aquarium light may also include controls that allow for a dawn/dusk dimming effect, like the ATI Sunpower dimmable fixture.

T5HO bulbs can be combined to create unique coloration. T5 reef lighting will often mix cool white, blue, and actinic bulbs to maximize color and growth. Unlike LED or metal halide, a T5 fixture will not have high intensity spots. The tradeoff is that a T5 fixture doesn’t have a shimmer effect. A T5 reef fixture can be used alongside LED or metal halide to blend shimmer with uniform light in the aquarium.
