Hi...some great posts here on moonlights. I just wanted to post a clearer picture of my tank at night. I'm not sure how to upload here so I'm linking it from the Members section. As you can see, the luminescence is amazing and I'm blown away to see what happens after dark. It seems much less bright than a cold cathode. I have it linked to a timer so when the strip light goes out, the LEDs come on. I highly recommend it. The reason I built mine is because I didn't know anything about tank hoods when I bought my 46 gallon bow.The hood is all plastic with a central strip of glass that only fits their strip light. There was no way to upgrade my lighting without having to buy a whole new hood and I didn't like the moonlights that stick on the side of the tank. Not only is it amazing to see who comes out at night, but, talk about the beautiful light blue glow. Anyway, if anyone needs help, they can PM me....the only skill really needed is soldering. I finished this project in about 3 hours. I added a dimmer on it, but, I don't think you really need it. SH
