Lamp

Distance

The Dist field indicates the number of Blender Units (BU) at which the intensity of the current light source will be half of its intensity. Objects less than the number of BU away from the lamp will get more light, while objects further away will receive less light. Certain settings and lamp falloff types affect how the Distance field is interpreted, meaning that it will not always react the same; see the page about light falloff.

• The Sun and Hemi Lamps are another class of Lamps which uses a constant falloff. Those lamps don't have a Dist field, and are often called "Base Lighting Lamps".

Energy

The intensity of the light source's illumination (from 0.0 to 10.0).

Color

The color of the light source's illumination. Opens a color swatch.

Negative

Let the lamp cast negative light.

This Layer Only

The Lamp only illuminates objects on the same layer the lamp is on.

Specular

The Lamp creates specular highlights.

Diffuse

The Lamp does diffuse shading.
