emergency lighting

The foot candle is determined by the distance that the luminaire is installed above grade as well as beam spread etc... The fixture has 1800 lumens and the battery appears to be able to provide 90 minutes of power for a CFL lamp.

RAB is a fairly good company and produces very good and reliable equipment.

Is that 1800 under house power?? Because when I pushed the test button a fairly dim light came on, say at least half as bright as the light under house power????

I would imagine that the 1800 lumens would be under normal conditions. The lighting rep should be able to give you the information on the foot candles at the floor under battery only power.

It looks like it's using a compact fluorescent light. A lot of them come on at half power or less, and take a few seconds to reach full output, especially in cold weather.

The manufacturer should have a chart showing light distribution and footcandles.
