I want my turtles to get adequate lighting for their shells, so I just decided to buy a new one...It cost $32.99, It is 24" long and came with the bulb, it is the instant on - no flicker start and it fits perfectly on top of my tank. It is energy efficient. The problem is; I wasn't paying attention when I bought it sinse this was my 4th attempt to replace the existing light and It says "All glass aquarium" on the box, says use with glass top only. Do not use over open water.
I have a screen on top of my turtle tank because I was told that the glass blocks uv rays...so what should I do? Can I use this over my tank? Does any one have this brand? Is it okay to place on screen. The one I bought before, was meant to sit on glass and I have not had a problem with it on the screen. Should I return this and keep looking? Please help! Thank you.
Here is a picture of it:
