Right off that bat:

"They don't need UVB... because they have adapted to the normal light bulb. It also gives out the same amount of heat. "

... Absolute idiots... It's not about heat. That's the absolute last reason UVB, in specific, is so important. UVB light reacts to pigment in the skin as a chemical reaction for vitamin D3. This vitamin is so important because it takes calcium and turns it into usable chemicals that make up bone matter. Not getting D3, either through diet or artificial lighting, can cause problems like Metabolic Bone Disease. Regarding diet, as far as my research has informed me, it's insectivores and vegetarian reptiles that don't get a sufficient amount of D3 in their diet, hence they absolutely NEED the UVB lighting. They don't just 'adapt' to it. That's just stupid.
