This Aquatic Life Electronic Ballast Kit features a four lamp configuration for driving four 24 watt High Output T5 lamps. The Ballast Kit uses pre-assembled components, so there is no need for wiring or special tools. This ballast is protected in a powder-coated housing that includes two on/off rocker switches, and can be easily suspended close to your aquarium. Triple-sealed silicone endcaps protect wires and lamp pins in even the most humid environments. Included colored identification tags on wires allow for easy pairing of wires to lamps.
