Are you still using a quad fixture though? This makes a difference in UVI level vs the single bulb fixture that the OP is using.I wouldn’t panic just yet, I don’t think the uvb is too strong I’ve raised my veiled on a 10.0 t5 hes 6 years old without eye issues. I would give your cham some time to adjust, if you’d rather use a 5.0 that would be fine, provide plenty of coverage on all zones for your cham to hide from the uvb rays when she’s had enough. You can also elevate your fixture to lower the uvb exposure or use another piece of screen to create another barrier between the uvb light and the cham, it will darken the lights tho. Good luck!
