This is a graphic to show that if your temps in your house is above 60-65 degrees at night, you don’t need a heat bulb. Actually a drop in temp is good on their bodies. Red and blue/purple lights will not blind then but can mess around with their vision and causing color to not look right. They also like it pitch black to see like many of us do. If your house is below 60-65 degrees at light, you will want to get a ceramic heat emitter (CHE) which gives off what but no light.
