Be confident in your purchase we're an Authorized AquaIllumination Dealer. How cool is that?!?!? NOTE: Bulbs not included. Add to your canopy with the Dimmable Miro-4 T5 High Output Retrofit Kit from LET Lighting. Having the ability to dim your T5 lamps will give you the same dimming control of LED lighting, while having a tried and true lighting source. Retrofit kits give you the flexibility to add T5 lamps virtually to any tank, while keeping a low overall cost. T5 lighting can either be the main light source or supplemental light to another light source like LED or metal halide. The overall spread and coverage of T5 HO lighting makes it really hard to beat. Quiet, cool operation Dimmable electronic ballast 0-10v dimmable control (controller required) Add to existing lighting, or as main light source Compatible with most aquarium controllers Flexible to many different applications Easy to follow instructions We really like the control and flexibility that T5 retrofit kits give. If you do not want to invest into a fixture, or you have a canopy that will not allow a properly sized fixture inside of it, retrofit kits are the way to go. They can be installed almost anywhere, and the color coded wiring harness makes wiring a breeze. LET includes high quality individual parabolic reflectors made from 96% German reflective aluminum allowing light to be evenly spread across your tank, virtually eliminating hot spots and shadows. Dimmable: The Dimmable LET Retrofit kits can be controlled by any 0-10v controller. A 0-10v control port is very common to find as an option on most common aquarium controllers. It is highly recommended for best performance, and bulb life, that all new bulbs be burned in at 100% for 50 hours before being dimmed.
