Working tools, free to use
Working tools built for people who specify lighting: no signup, no email wall, no catch. Each one can pour its result straight into your project brief, so the request you send us is already half written.
Start with your brief
Gather the pieces, quantities and constraints. Then use a calculator to refine a decision.

Chandelier size calculator
Enter your room dimensions and ceiling height, get an indicative fixture diameter, height and hanging clearance.
Pendant hanging height simulator

Enter your opening date: the planner walks the custom lighting timeline backwards and tells you when your brief must leave.
