I use Hagen Night Glo bulbs on both my water dragon and day gecko enclosures.....I like the looks, I guess.
Now, I never truly understood the red bulb concept...I recall reading that most reptiles could see it, but it was so subdued it didn't keep them away...same with the blue bulbs. I've also heard from other herpers that the blue bulbs heat less.
What is correct? Can they see red? Blue bulbs? Is it OK to use?
