When the metal halide goes in the greenhouse it is going to be on a timer and will only be on for 2 to 3 hours for basking in the morning. As for the Parson if he is free ranging or in his cage he has enough places where he can rest that won't expose him to UV rays during the 2 to 3 hours in the morning. You are wrong to think that Parsons do not bask mine does not stretch out in the sun like a panther, however, in the morning he sits under the Zoo med tubes every morning for UV requirements for an hour or two then spends the rest of the day walking around his cage or resting in the shade. This species I think mostly habitats the crowns of large trees and does not live in the understory, as seen with their long tails designed for life above ground. A species that lives near the ground would be Critatus as shown with their lack of a long tail. The long tail is a sign of crown or canopy living as seen in Bifidus, Balteatus, Oweni and others and Parsons have got a long tail. Plus when free ranging in the greenhouse my Parsons behavior supports this as he regularly stays in the tree crowns or higher in the branches. As for the halide bulb there is a bulb that is compatible with my metal halide system that is UV appropriate for reptiles , from a source recommended from others on this forum and is normally used for reptiles for zoos. My metal halide runs unbelievably cool and puts out heat just a bit more noticeable than tube lights.
