Awesome! Okay, so red light. Beardies are from a very bright environment. It is hot, and sunny. Contrary to what researchers used to believe, they actually can see red light, and it looks like twilight to them. So there are two problems - during the day it hurts their eyes, as it seems dim all the time. Think about how your strain to see in the evening as twilight approaches. The other issue is that at night, it will keep them awake. What you want is a bright white light during the day and no light at night. As long as it stays above 65F at night, you don't need any heat source (by the way, don't use a heat pad or heat rock as they can be burned by them). If it gets below 65F, you will need a ceramic heat emitter for night time.
Make sure appropriate thermometers (digital with probe or temp gun) and appropriate UVB (ReptiSun 10.0 TUBE UVB only) are also on your list!
Let me know if you have any more questions!
