Be sure the light from your basking light and UVB light overlap. You want the rays from each light to overlap as it allows for better absorption in your beardies. I really think this is easier to accomplish with the long tube UVB versus a small bulb. When I get home I can post a picture if it helps. I also had a 75W UVB in a 40g breeder and got the proper basking temps with no problem, but my light was in the tank, and not on top of a screen. So the distance may be preventing you from getting the heat you want.
And you are correct, you don't want the screen interfering with your light, so if there is any way to lose the screen, or cut a hole, that would be preferable.
ETA: I get the black soldier fly larva and rinse them really well before offering them up to my beardie. He gets about 10 of them a day and this is a great way to get moisture into him. He is not a drinker and doesn't have a water dish. I also mix his dusted crawly food in with his mustard and collard greens, with some shaved butternut squash. He does well with the green but will only do the squash if it's accidentally attached to his dubia roach. Eh, it is what it is. I don't over worry it. As long as he gets some veg every day, I'm happy.
