for heat, any light bulb will really work,
but some work better than others, I use regular 40w bulbs on my snakes that have basking lamps,
but those do not make acceptable substitues for full spectrum lighting.
icandescent light is icandescent light, all the reptile companies do is slap their label on it.
Sure some of them are more suited to directing heat in one direction, but there are bulbs that are equal to most incandescent reptile basking lights.
as far as the other questions,
you may want to ask him/her about it before you assume its not being properly cared for.
