| Not really a home lighting question, but I am looking for a snake light that throws off 10 foot candles at a distance of 6 feet. I'm not finding those kind of specs when I google around for high-illumination lights.
Can anyone point me toward a source, type of bulb, recommended spec/configuration, or anything else to help me get a light that will meet my needs? |

| It is in elevator code. Any help with converting it to what the rest of the world uses? |
|
| It is no longer used much since it is not adequate for defining luminous intensity reliably. You might be able to convert it to lumens, but the geometry involved make s it a less than simple issue. |

| 1 foot candle is ~ 10.764 lux. Possible alternatives could be |

| Or one lumen per square foot. An isotropic (uniform in all direectins) one-candela light-source emits a total luminous flux of exactly 4Ï€ lumens (since a spheres is 4Ï€ steradians). A partially covered source would emit a differnet amount. Is this for commercial work? |

| This is for an elevator car top and I just want an inexpensive light that's bright enough. No desire to build our own. So if I found a light that was 410 lumens or 11 lux, that would emit 10 foot candles at the source and then, presumably, dissipate over distance? |
