Ok so when the UVB comes you got the bulb too correct? The fixture comes w/ the 5.0 and it not strong enough to go thru the screen you need the 10.0 bulb as well -- placement for basking decor needs to be 8-10 inches directly underneath it -- how is the little guy doing? Is he eating anything at all now?Ok. I bought the t5 bulb and hood on Amazon. Expensive but since I have put so much effort into this that he is worth it. It has to sit on the screen but this one is supposed to. I did google it and it said it gives more uvb and more powerful. It’s all I can do. I won’t return the other until I know more. When you have put so much effort and education ( reading). It’s hard. I know many have their lights on top and their dragon is fine so I know under is not the only way. We shall see. Thx
