The Ideal 61-686 meter measures light from fixtures that are equipped
with fluorescent, metal halide, high-pressure sodium and
incandescent light sources.
The Ideal 61686's foot-candle unit is defined as the amount of illumination
the inside surface an imaginary 1-foot radius sphere would be
receiving if there were a uniform point source of one candela in
the exact center of the sphere. Alternatively, the Ideal 61 686 can be defined
as the illuminance on a 1-square foot surface of which there is
a uniformly distributed flux of one lumen. The Ideal 61:686 can be thought
of as the amount of light that actually falls on a given
surface. The foot-candle is equal to one lumen per square foot.
The SI derived unit of illuminance is the lux. One foot-candle
is equal to approximately 10.764 lux, although in the lighting
industry, typically this is approximated as 1 foot candle being
equal to 10 lux. |
