Lighting Design Calculator


Our simple to use lighting design calculator is a quick and easy way to see how many luminaires of a certain product you will require to light a room to the general SLL (CIBSE) lighting level reccomendations.

General assumptions for the calculator are that rooms are square/oblong, have a uniform ceiling height and that light fixtures will be equally spaced. Natural light sources such as windows and sky lights are also not factored in. Should you require a more comprehensive lighting design, please contact our lighting design team or your local BELL representative.

Office type rooms assumed reflection factors of 20/70/50% for floor, ceiling and walls respectively
Warehouse type rooms assumed reflection factors of 20/50/30% for floor, ceiling and walls respectively
