Yes most filament lamps emit a tiny amount of UVA. But I think your getting confused as it's UVB that reptiles rely upon for the D3 cycle.
In most setups a 10% T8 lamp can not re-create a wild level or index of exposure.
As indicated already Arcadia D3+ 12% T5s do allow you to do so in a vet energy efficient way.
There is loads of free stuff to read at Arcadia Reptile : Arcadia Products Plc
have a look at the D3 cycle section, lighting guide and practical reptile keeping magazine sections.
