So I just got a solarmeter and currently my reptisun T5 HO is in a reflector about 12 inches from the basking shelf I have and for the most part the UVB in the tank is fine except directly under the UVB tube the solarmeter is reading up to like 13 which I know anything above 8 is probably not good. Question is, how should I fix this? Get another fixture that isn't a reflector or lower the basking shelf? He hasen't been avoiding the basking spot at all but just worried the UVB is too high.

You can lower the basking shelf or raise the UVB we need CooperDragon to advise better on the amount your getting GE 15 ft. Cable Ties, Hook and Loop Spool, Black-10375 - The Home Depot
this stuff works great its like a Velcro strap cut into strips then wrap around your fixture

Changing the distance and adding shade is the best way to cut uvb output. The bulbs decrease a bit in output as they break in too. I usually shoot for somewhere around 3-6uvi over the main basking area with a gradient down to 0 uvi elsewhere. Some areas that offer higher ubv is ok within reason, but give them space to move away if they want to.

Thanks, I'm going to lower the basking shelf to hopfully decrease the UVB some, but is it harmful to them to have an area that has pretty high UVB like 10 or so? Cause he doesn't really seem to avoid it but I just wanted to make sure it doesn't cause any damage. He does occasionally close an eye but I thought that was more related to him being sleepy but maybe it is the UVB.

They'll move out of the way if an area is too intense (as long as they have space to do so). They're really good at self regulating so as long as they have options available, they should be OK. The UVI in their natural habitat can get very high (I've measured 14 and heard of higher) but from what I've read, they tend to hide during these times and bask in mid morning and late afternoon when the UVI is closer to the 3-6 (ish) range.

Mirage entered brumation yesterday, I'm gonna miss hanging out with my little guy.
Getting ready for another day. Feeling sleepy. 😴
I just walked into my room and instead of looking at me, Swordtail's eyes darted directly to the ice cream drumstick I'm holding
Finally replaced Swordtail's substrate
I miss you so much, Amaris 💔
