bulb advice

[theimmortaljedi]

A few days a week the temp in my house drops a little by 5 or ten dagrees. I read online that even though I have 100 watt basking bulb that is I switched it on those days to 100 watt household bulb it will warn it up more.
Shoul I do this? Is this true that a household balb of the same wattage will be warmer? Should I change the bulbs on some days when my house is cooler? ANY and ALL advice will be great. PLEASE HELP!!
thanks

We need to know the temps of the basking spot, warm side, cool side. Inside the tank. And if the 5 to 10 degree swing is observered in the tank at those spots as well. A night drop is fine when your bulb is off as long at it isn't much below 65.

about 60 at night.

Is it true that 100 watss of a house bulb is hotter then 100 watts of a pet store reptile bulb?
thanks again.
