I have a 75W Day Blue bulb that came in the kit I purchased and I am curious whether or not this is harmful to my gecko. It really would be used to keep the air temp a little warmer, but I know there has been talk about it hurting their eyes or something so I want to be sure. My all around air temps are roughly 73-74 degrees so it isn't cold, but I thought it would be beneficial to just keep things a bit warmer.
