Point of Light
Turn a prim into a light source: lamps, headlights, candles and ambient light.
Makes a prim emit light, like the Light checkbox in the build tool's Features tab. Lamps, headlights, candles, ambient mood lighting, all switchable from a HUD.
Fields
| Field | Required | What to enter |
|---|---|---|

Color | for ON | RGB vector. Default white <1,1,1>. |
Intensity | for ON | 0.0–1.0. Default 1.0. |
Radius | for ON | 0.0–20.0 meters. Default 10. |
Falloff | for ON | 0.0–2.0, how fast the light fades with distance. Default 0.75. |
FOV | No | 0.0–3.0. Projector field of view; 0 for a normal point light. |

Notes
- Second Life renders a limited number of local lights per scene (viewers typically show the 6–8 nearest). Fewer, stronger lights look better than many weak ones.
- The FOV/Focus/Ambiance fields configure the prim as a projector (spotlight). Projectors need a texture set in the build tool's light settings to show a shaped beam; without one they behave like a cone light.
- Light does not cast shadows unless the viewer has shadows enabled.
Example: a lamp with a switch
See Light Switch for a single-button ON/OFF lamp using a variable.
