什么是 Recessed Light Calculator?

I maintain Recessed Light Calculator, a free, no-login browser tool for initial recessed lighting layouts in rectangular rooms. Adjust room size, fixture lumens and assumptions, then inspect the estimated fixture count and 2D spacing. Export a draft as PNG or CSV. This is a preliminary planning tool, not electrical or photometric design.
