Well Bryce that depends on what animal you are providing heat for. For a snake, yes you'd be better off with a UTH. But for many lizards that need overhead light, a CHE or other heat bulbs are better.
Also, a good heat light won't burn out as quickly as a normal bulb (which tend to fry pretty quick if you keep them on 12hr/day). That coating is the "blur" the light, so it isn't as bright if you look directly into it.
