How to plan a lighting scheme
The layered thinking behind a room that reads correctly at any hour.
Published 2025-03-18
A lighting scheme is not a list of fittings. It is a sequence of decisions about what a room is for, when it is used, and how it should feel. Begin with the absence of light, then build up.
Start with use, not fittings
Before a single luminaire is chosen, map the activities that take place in the room and the hours they happen. A kitchen used for cooking at 8pm needs a different quality of light than one used for hosting at 10pm. Use defines layer, and layer defines the brief.
Build three layers
Ambient light provides a base; task light protects the work; accent light gives the room its character. Most schemes fail because they collapse all three into a single ceiling grid. Keep them separate, dimmable, and individually controllable.
Control is the fourth layer
Scenes matter as much as luminaires. A room that can shift from preparation to dining to film with a single command is a room that is used well. Specify the control system with the same care as the fittings.
Respect daylight
A scheme that ignores daylight is a scheme that fights it. Plan for blinds, exposure and orientation, and let automated response dim the artificial contribution when the sun is doing the work.
KEY TAKEAWAYS
- Begin from use and time-of-day, not from fittings
- Keep ambient, task and accent layers separate and dimmable
- Treat control as a layer, not an afterthought
- Design to work with daylight, not against it
