Hi AV lovers!

I have a question about the light and "warmth". I have some AV babies in the office and as I want them to have lots of light I actually put my lamp right above them. (5 inches) for 8 hours a day, when I am at work. The problem is that this lamp also produces warmth and I am not sure if it is good for AV's. Obviously 5 inches is not that close but still they are getting some of the warmth, I can feel it when I put my hand down there.

What do you think about this solution? Do you think they would be better off with less light (regular office light) and no warmth from the lamp?

thanks for your help!
