I recently got these lamps from someone who was giving away their leopard gecko enclosure does anyone know what each of these light are/do, i can't quite find them online either, all are different lamps exept for the last two pics.
The issue is more what kind of bulb each light has. The middle ones are regular dome lights and probably have compact fluorescents. You can figure out for yourself whether the bulbs in these fixtures are giving off more heat or more light. They may be UVB but since you don't know how old the bulbs are you should just assume that they are not providing any UVB anymore. If you're thinking about using these lights for leopard geckos, they may be appropriate, though I don't think they're necessary.
