From BRS site: Aquatic Life's T5HO Hybrid Lighting Fixture lets you combine your favorite LED light module between two banks of T5 lights. The T5 lights are powered by HEP Ballasts for fast firing and excellent color rendition. Each T5 lamp has their own reflector and is held in by traditional bulb clips that have a plastic coating to protect your bulb. Aquatic Life has even gone above and beyond by including silicone end caps that make changing bulbs super-fast and easy.

When you combine LED and T5 lighting you can have the best of both worlds. T5 lighting has a proven track record with their full spectrum bulbs and edge to edge coverage, and almost anyone can have success with the right fluorescent lamps. Being in the 21st century everything we own must have some type of control, and that is where T5 fails, but LED shines. LED lights are known for their ability to ramp up and down giving dusk to dawn effects while being able to change colors and spectrums throughout the day as well. LED lights provide great shimmer, and when paired with T5 lights almost creates a realistic look that you would actually find in a shallow reef. 

Pair the Aquatic Life Hybrid fixture with some of the most popular LEDs like Kessil, Ecotech, or Aqua Illumination for a successful combination of T5 and LED lighting. Each hybrid fixture includes two different mounts that can accept some of the larger lights like the Kessil A360 and Aqua Illumination Hydra FiftyTwo HD, but also some of the smaller modules like the AI Prime HD and Ecotech XR15w lights. Includes mounts for the following models of LED Lights:

> Ecotech XR30, Ecotech XR15

> Kessil A360

> Aqua Illumination Prime, Aqua Illumination Hydra TwentySix & FiftyTwo

The mounts can accommodate a variety of aquarium LED lights. Two brackets are included and between the two brackets, about 90% of LED light modules can be mounted between T5 lights.
