I am looking into setting up a new terrarium, and ditching overhead heat lamps. I do, however, still want a display type of light on top. I will be getting plexi glass cut to cover the top of the screen, and want to have a section cut out where I can place a hood with some sort of light source. I will have it set with a timer, to turn off at night. I am not really interested in a uvb lamp, beacause I would be paying extra for the uvb. Anyone know what my options would be with a light source that puts out little or no heat? Is just a low watt bulb what I need? Thanks, Matthew
