Lighting Levels* The CIBSE (Chartered Institute of Building Services Engineers) produces a Code for Interior Lighting which gives lighting requirements for areas. This means, for example, that for a room with an illumination level of 200 lux, if this is taken as the minimum level, then the maximum level in another part of the room will be no higher than 714 lux as shown below. *Note: Complete uniformity is impossible in practice, but an acceptable standard is for the minimum to be at least 70% of the maximum illumination level.
