I'm no expert as only just researching this stuff now to start setting up my own viv, but don't you need a daytime source of basking heat that emits light too.
I've read that most diurnal species can seek out light for basking and can differentiate, and that the ceramic heaters are not good for basking daytime heat sources.
I'm thinking the ideal setup is just use ceramic at night time only on pulse stat, then turn it off in day. Then in the day have the UVB strip and a halogen basking lamp (with UVA output too for 'psychological benefit' too lizard) on a dimmer stat. Only prob with this is that is req two thermostats and that is pricey! I don't know how else to do it though.
An alternative to the daytime part of the setup could be use a MV UVB bulb as the basking light and chuck out the UVB strip light, and just have a seconday non-UVB bulb to give the lizard an alternative non-UVB basking place so it can photoregulate and not get stressed by only being able to bask im UVB.
I'm slightly confused at what to do now though, after reading many conflicting things
