Lamp LayersLight one room in layers, then set the dimmers.
Put the room's lamps and the spots where people read, relax, work or eat on a plan. The page estimates the light each spot gets, checks it against the target for that activity, and shows which layers the room is missing.
1 The room free
Spots where things happen - up to 4
Lamps the ones the room has now - up to 10
New lamps and spots land in the middle of the plan - drag them to where they are. Lumens are on the bulb's box (a 60 W-style bulb gives about 800).
2 The plan free
Drag a lamp or a spot, or focus it and use the arrow keys (0.1 m a press). The glow is the estimated light at table height.
3 The lighting plan metered
One run reads the room and the page's estimates. It writes a dimmer scene for each spot, the lamp or two worth adding and a check to make first. It never changes the estimates; the page re-adds every scene's light and places every suggested lamp.

How the page estimates the light
Each lamp type has a typical height and a share of its light aimed down. That share spreads from the lamp and fades with the square of the distance; the rest bounces off the walls and ceiling and arrives everywhere, more in a room with light walls. The page adds every lamp's share at each spot, at table height, and compares the total with the target for the activity: reading and desk work 300-500 lux, relaxing and dining 150-300, a kitchen counter 300-750, a bedside 50-150. Daylight is not counted.
The verdict, checked in order: short of light when a spot stays under its target with every lamp at full; otherwise a layer missing when the room has no ambient lamp, no accent lamp, or no task lamp while it has a reading, desk or counter spot; otherwise ready for scenes. Evening light reads best at 2700-3000 K and night light at 2200-2700 K.
Estimates from a plan, not a lighting survey, and not professional advice. Keep every bulb within its fitting's maximum wattage, use dimmable bulbs on a compatible dimmer, and leave new fixed lights and any wiring to a qualified electrician.
