SMALL blue tank light
Very small LED blue light - great for say a 5 gallon or may 10 gallon for that "moonlight" effect or if you are trying to up your blue's in a nano marine aquarium. Not powerful enough to have any effect on Par beyond a 10 gallon. lost a star because there are no presets and you will need a timer plug otherwise this is just on/off function. USB plug may be a plus or minus for you. I do like that it is what it is, a nano blue LED light and at a very reasonable price point. Read more
