have you every heard of the right tool for the job? sometimes a standard wrench fits a metric nut but that don't mean you should use it. Why risk the health of your cham listening to this guy do things right and get a legit bulb.
What right tool for the job? The bulb that matters is the UVB light, which he has. This produces a special spectrum of light and so on, and that matters. But the heat bulb doesn't have to produce anything but heat... we really could just use a ceramic heater to produce heat and no light. Just because there's a reptile on the box doesn't mean it does anything special. There's nothing more "legit" about it.
Seriously, don't get fooled into spending a few more dollars because there's a lizard on the box. Breeders and experts use household bulbs for a reason, they know not to waste the money where it doesn't matter.
