Love of Animals and I said that if there is a screen between the bulb that has less than a 1/2 inch grid (okay, I said that last part), use the 10.0. The 5.0 is for unobstructed 12 inch or less distance.
I was out on a screen search today, because my RES has started trying to climb through the hole I cut through my egg crate to give me an unobstructed path from the bulb to the basking area. The only screens I was able to find are the critter screens at petland which have a 1/8th inch grid. You can rest your light right on these screens, but they block a lot of it. If you have a screen with less than 1/2 inch grid go with the higher power light. Egg crate (light diffuser) has a little more than a half inch grid, but it is thick, so you lose a lot of light through reflections from the plastic grid, that is why I cut a hole through mine for the lights to shine through. I am using a 5.0, about 8-10 inches away from the platform (depending on evaporation), along with a Turtle Tuff halogen for the UVA heat.
