I don't think a regular incandescent household bulb would get hot enough. If you can find a halogen flood light it would work nicely. I use a PAR38 halogen flood light as a basking light and it works well. It can also be dimmed to get the temperatures just right. You should be able to find one at most hardware stores.
In your perspective does my baby bearded dragon look healthy or unhealthy? Does she look bloated? she is active and eats very well also she is in her basking spot all day
