The decision came after monitoring by the CIBSE's Society of Light and Lighting into the use of lighting technology.
At a press conference on 3 July, Mike Simpson, president of the Society, warned: "Some designers are concentrating on the Cat 2 luminaire classification and ignoring other, equally important, aspects of the Society's recommendations for lighting."
The Society intends to release a factfile in September to effect the withdrawal of the category system. It will also emphasise the factors needed for good practice, such as luminance levels being checked against an installation's specific needs.
