Top Heat Top heat warms the entire terrarium and provides heat for your pet to bask in. Incandescent flood lamps or bulbs can be screwed into a bulb clamp and attached to the side of the terrarium. The light should be positioned above a branch or other elevated feature in your terrarium. Your reptile will move up the branch to increase the heat it absorbs and move back down to reduce the heat. The residual heat will warm the rest of the terrarium to the desired coller range.
Incandescent bulbs come in various color shades.
The following are other examples of heat sources. These bulbs can also be used to provide top heat. Infrared bulbs have the advantage of being left on 24 hours a day because only subdued red light is emitted. A ceramic heat emitter looks like a floodlight, however, it only puts out heat and not light. Heat emitters work well because they can be kept on 24 hours a day.
