Hi, I got a bearded dragon a few days ago and his name is Sunny.
I’m new to this so I don’t know how to make the images actually show up but here are some links to pictures of him that hopefully work.
Welcome to the forum! Sunny looks happy and healthy. Please let us know if you have any questions about his care and we'll be happy to help as much as we can.
The UVB fixture looks like a Zilla Slimline T8 or similar. It should be fine in a small enclosure (20gal or so). Just be sure to remove the clear plastic from in front of the bulb as that will intercept the UVB.
