Shines brighter than I expected. I bought a pair to update my old fluorescent hubcaps from the early 1980's. I cored the old 2 foot caps and screwed them to the caps through the adjustable legs. Quickly removed and re-soldered the power wires so I could route them through the holes in the hoods. With the new LEDs, the fish looks much brighter. The price was great, fits perfectly, just what I was looking for. A word of caution, they're nowhere near waterproof. Don't let them slide into your tank. Mounting in hoods is no longer a problem, but I don't think I would dare to put it on the tank with my own legs.
