I think you've misinterpreted what I was trying to say. It's ok to use 10.0 bulbs, and for some species, more beneficial than a 5.0. Being everything is set up properly accordingly.Can't speak for all species but if your chameleon basks early morning or late afternoon and/or is mostly exposed to indirect sunlight (because of clouds, trees etc) you're probably going to need a 5.0 lamp.
Just be careful with upgrading your lamp since to much uw/cm2 may just be as harmfull as to little... (I know I burn like a shrimp on a sunny day from getting to much)... Adding a good reflector will also increase the range...
Exo terra also introduced their UVB Bulb Index to replace the old 2.0(dart frog), 5.0(rainforrest), 10.0(desset) gradations so it's good to see there will probably be more flavours to choose from:

Sorry, I don't know how to explain it clearer... Read the links I've posted above I suppose...
