Add or change lights to provide more even illuminance.
Both dawns had a maximum illuminance of 275 lux.
Can be used to determine the direct illuminance on a plane.
Design service illuminance is derived from the standard service illuminance by taking account of the modifying factors contained in the flow chart.
For example, they may insist on a higher illuminance.
For this study the lighting control was defined with a set point of 500 lux as the required illuminance for office use.
In some cases T5 tubes are even cheaper because of their slightly lower illuminance.
Measurements include directional luminous intensity, illuminance of lamps and meters, luminance of sources and meters and total luminous flux.
Standby schemes may be to provide from 5% to 100% of the design service illuminance according to circumstances.
The average horizontal illuminance over the whole area on the unobstructed floor should not be less than 1 lux.
The larger OUT cell, also in a cosine corrected mount, is used to measure the illuminance from a whole overcast hemisphere.
We also should be looking to challenge the concept of an average maintained illuminance across the working plane.
