The Repti Basking Spot Lamp has a unique, patented "double reflector dome".

The tight beam allows up to 35% more heat and light to be focused at a given spot. This ability to focus the Spot Bulb on a branch or a rock, allows for the reproduction of a more natural basking environment. Repti Basking Spot Bulbs also provide vital UVA rays which promote breeding, feeding and are beneficial to a reptile's psychological well being.
