The compact bulb shouldn't produce much heat especially if it's energy efficient. It's a 2700k bulb so it will have a warm/amber color to it vs a daylight bulb that is around 6500k and will look more like outdoor light. Some LEDs could make things look distorted but I think it depends on the type used. It probably isn't as big of a deal when used along with a UVB tube and a basking light because it will blend in more. It might be best to get a wide spectrum or daylight LED if you use one. Arcadia makes some for plants called Jungle Dawn.
