Frequently Asked Questions: LED Powermodule

Using a hybrid fixture allows users to combine the benefits of multiple forms of lighting together to improve spectrum, intensity, and coral growth. T5 does an excellent job of blanketing corals with light, but LED allows you to dial in the exact color you are looking for.

The purchase of each ATI LED Powermodule fixture includes a hanging kit. This hanging kit will allow you to safely suspend the light above your tank. You can also adjust the hanging kit to set the lights above your tank to your desired height. For detailed instructions on properly hanging your fixture, please refer to the “How to Properly Install an ATI Hanging Kit” blog post.

The height of your fixture depends on various factors, such as the size of your fixture and tank. If you mount the fixture higher, you will have more spread but less intensity. On the other hand, you will have increased power if you mount your fixture closer to the water level.
