When selecting an emergency lighting product, the installer should bear in mind the area needing to be covered and select the most appropriate solution to meet those requirements. Manufacturers are legally obliged to have key product data available. Ensure the data has been verified by a trusted third-party, for example, currently, the Lighting Industry Association [LIA] or Lux-TSI; that information should be checked by the installer.
Emergency fittings will be installed either as replacements or a new installation, and it is imperative that the replacement has an equivalent light output to ensure safety of occupants.
