Posted By Ian stevenson I have carried out an indoor lighting assessment in an area where workers are constantly reading written information. The light readings were measured at around 150 Luxes. I understand they should be a minimum of 300 luxes. Any comments would be welcome.

Posted By Adrian Watson Ian, The law, Regulation 8 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires that: (1) Every workplace shall have suitable and sufficient lighting. (2) The lighting mentioned in paragraph (1) shall, so far as is reasonably practicable, be by natural light. (3) Without prejudice to the generality of paragraph (1), suitable and sufficient emergency lighting shall be provided in any room in circumstances in which persons at work are specially exposed to danger in the event of failure of artificial lighting. Whilst lighting levels are specified in HSG 38 Lighting at work, it should be remembered that these are minimum levels, which appear to be derived from the CIBSE 1967 code for interior lighting. Good lighting is specified in the current edition of the CIBSE code for interior lighting (1994). This recommends an illumination level of 500 Lux for general offices.

Posted By Ken Taylor There seem to be various recommendations around on this subject. 300lux is recommended school classroom level. Americans seem to prefer at least 500. 300 has been said to be preferred when using computer screens, the suppliers of light meters tend to include recommended levels for different types of work, etc, etc. In any event 150, almost certainly, will be inadequate for your staff's needs and will require uprating. Sometimes replacing tubes or changing single tube luminaires for doubles is all that is needed.
