I've used the 12% HO bulbs from Arcadia, but not the other. The screen will filter out some of the UV and light. How close will the bulb be to the tortoise? I prefer to not use indoor UV when climate allows.

it will be about a 9 inches-10 inches away. I only want to use UV lighting right now because of the cold weather we have been having here.
