IceCap has a new LunarLite – Blue LED Retrofit that will be available soon. This should work in nicely with their new Reef illuminations light fixture that was released at MACNA. IceCap had this to say on their website:
The LunarLite LED tubes have the same look of a standard T5 tube, but they are powered by a low voltage transformer, not a fluorescent ballast.  The T5 form provides better spread of the light over the entire aquarium. Encasing the LED’s inside a T5-style tube protects them and their circuit boards from the harsh, salty, humid environment that is your normal saltwater aquarium. The IceCap LunarLites have an aluminum heat sink on the back side of the tube to dissipate what little heat they generate.
LunarLites are highly efficient and very reliable but we know the reason you’ll want them is what they will do to the appearance of the corals. They are designed to excite the green fluorescing proteins in corals. They particularly bring out yellows, oranges, and greens. If you think your corals look good under actinics, you haven’t seen anything yet! Mushrooms, zoanthids, Ricordea, and most any fleshly large polyp stony corals look amazing under the LED’s.
The LunarLite retrofits ship with mounting clips to secure the LED Tubes to a canopy, commercial hood or existing fixture. The weight should not be an issue because the 2-foot unit is only 4 oz.   Power connection to the LunarLite is a power tail with a quick connect to a low voltage power supply, no hand wiring required.
While working with the Reef Illuminations fixture, these also will work in other T5 fixtures so you aren’t forced into buying an IceCap fixture if you wish not to. These will begin to ship in mid-December with an MSRP not yet announced.
