Yes. I foundmy chams liked the warm glow of a normal household lamp or helogen lamp over the colored lights. It was rare they woudl bask under red, because it looks odd to them and blue also must have been odd looking because they didn't seem to go to it.
For my adults I personally use 50w halogen PAR20
flood lights. I angle them and this helps the cham to bask more easily. Think about how a cham basks and when. They bask in the morning to warm, when the sun is lower in the sky. So heat lamps pointed straight down doesn't seem to make a whole lot of sense. Especially since the light pointing down can cause dorsal crest burns much easier than a lamp that is pointed into the cage (from the top) at an angle.
