Question: is it battery powered
Document: This is one of the few biocube specific aquarium products I have been satisfied with. It gives a brilliant twinkle to my tank that I don't have with my standard tank. The stock lights do not twinkle either... I highly recommend adding this to your biocube if you made the mistake of buying one. The skimmers and uv filters are horrible tho. And with limited space there are really no other options for them.
LED bulbs are the way to go in this high electric bill era. These are bright, clip into the biocube hood 29 with ease.
I replaced my blue light with this white light I love it looks nice and saves on my electric bill. Can not find these in the local pet supply stores yet. You think if they sell the tank they would at least have the parts to go with it...
I have a 14 gallon Biocube which came with the blue moonlight led. I added this for creating a dawn/dusk effect. The color adds a noticeable shimmer to the water and my corals seem to like it. Definitely a must have.
I actually bought 4 (2 white and two blue) to populate the open slots in the Coralife Biocube 29's hood. They slipped in with ease and worked as expected. If all you want to keep are &#34;softies&#34; (mushrooms, star polyps and leathers, etc) these are a nice addition to the supplied lighting in the hood.
Great daylight bright shine, installment is easy fits like a glove perfect.Led are well separated for nice shine to water.
Great Product and both heat and electricity use are reduced. My Bio cube runs hot with the stock lighting system water evaporates very quickly. I purchase this product to reduce both the heat and energy use and it helped with both. I still need a chiller as the BioCube is poorly designed and doesn't dissipate heat well.
Answer: no
