I have a less-then-a-year-old bearded dragon named Henry. He has one of those UV lights that is small( the size of his basking light) and I know this is NOT what you should have for a bearded dragon. The reason I haven't gotten a proper UV light yet is because my mom doesn't think we need to . Henry's cage is beside a window, and my mom's boyfriend says that he doesn't need it because he has the UV from the sun. I researched it and UV from the sun CAN pass through windows, but I know they still need more. It's going to be hard to convince her, so I want people to reply so I can show her how important it is and how much other people care. Thanks for reading and please reply!
