How to Buy a Black Light for My Eclipse Fish Aquarium

The Eclipse is a self-contained aquarium system with the filter in the hood. The lighted versions come in 3-gallon, 6-gallon and 12-gallon configurations. There are also 2- and 5-gallon systems, but they're not lighted.

  1. Bulb Sizes

    • The 3- and 6-gallon Eclipse systems use a T5 fluorescent bulb. The System 3 uses a 6-watt bulb and the System 6 uses an 8-watt. The 12-gallon system uses a 13-watt compact fluorescent bulb.

    Black Lights for Smaller Eclipse Systems

    • The T5 6- and 8-watt bulbs are standard fluorescent bulb sizes. You can find black-light versions of these bulbs online, or at stores that sell lighting equipment.

    Black Lights for Larger Eclipse Systems

    • The 13-watt compact fluorescent bulb in the Eclipse System 12 uses a dual-pin configuration. These bulbs are not available as black lights.
