I'm fairly certain it's the regular red not the infared because it's the only one that comes in 40 watt. It's pictured here.
Red Bulb
I hear you about the sleeping thing. I had to throw a towel over the front of Seneca's cage because it's so bright. My mother says my room looks like a pricey lady house. Err..brothel...can I say brothel? I can live with the light only because the temps are just right now but if there is reason to think it hurts their eyes, I will switch to an ESU 50watt and get a dimmer for Seneca. (Jose's is already on a dimmer)
