Hi. the bulb i have right now isn't bright enough and i thought it was because of it being old so i bought a new one and still doesn't give off much light. i was wondering if i could use a normal 60W household bulb for light for my iguana. he falls asleep during the day because it isn't bright enough for him. i have a 60W soft white household bulb on him now so he doesn't fall asleep during the day but i don't know what kind of effects this will have on him. is this alright or will it harm him?
