All of that sounds good, and your substrate sounds fine too, but I'd get rid of the turf.Warm side 30C
Cool side 20/25C
Basking 35/40C directly under bulb
And around 20C of a night but has been varying lately due to the warm temperature we have been having lately so we have been bathing him regularly.
My best guess at this point is that bulb. Those should not be sold. They should be discontinued and taken off the market. They keep selling them become people keep buying them. Not every bulb causes this problem, and that has been part of the reason why this continues. Some small percentage of them burn reptile eyes, and the rest do no harm, but they also don't do much good as a UV source either. There is no way to know ahead of time which ones will burn eyes and which ones won't.
