In my LFS most the marine tanks have a blue or black light which makes the color in the tank vibrant, i was curious if these are the lunar lights or just regular black lights, i was lookin at the lunar lights online, and does anyone egree with me that the more expensive ones are a scam, I mean with minimal knowledge of electronics you could just mod your hood with an inexpensive led of the desired color for way cheaper than what they are charging for them, and i saw some of them just come with a screw so you still have to mod your set up, anyway, what are your thoughts on lunar lights?
