I currently use domes with a spiral UVB bulb. After all these stories I'm reading how the spiral bulb can actually cause eye damage I decided to switch to a linear bulb. I am just having a hard time trying to figure out how to place the fixture when I use shallow storage type containers (maybe 5-6 inches high). I am assuming it's too low to just rest on top of the lip of the container (then being only inches above the bedding)? I was also thinking possibly trying to velcro the light to the shelf above the habitat (sounds confusing but I have both the habitats sitting in backless book shelf), but then there is a possibility the little heat the UVB bulb gives off could melt the velcro sticky and fall, and I don't want that. Any Ideas??
