A whole-home lighting plan

Almost everybody starts a lighting project by shopping. It is the wrong first move, and it is expensive, because the most common cause of a dark room in an ordinary home is not a missing fixture - it is weak bulbs in the fittings that are already there.

So stage one costs nothing. Walk the house with a notepad and write down, for each room, the number of sockets and the lumen figure printed on the bulbs in them. Add them up. Compare against the target for that room's size and use, from how many lumens does a room need.

This routinely changes the plan. A living room with five sockets holding 450 lumen bulbs has 2,250 lumens in it; the same five sockets holding 1,500 lumen bulbs have 7,500. That is a transformation for the price of a multipack, with nothing to install, no cord to route and no landlord to ask.

Stage 2 is free if you do it with stage 1. Since you are buying bulbs anyway, buy one color temperature. Mixed warmth within a single sight line is the most common thing that makes an otherwise fine house look slightly wrong, and it costs nothing to avoid at purchase time. 2700K throughout living spaces is the straightforward answer, with cooler light reserved for a laundry, a garage or a workbench.

Stage 3 is where daily life improves most. Task lighting is disproportionately valuable because it is light delivered exactly where a real activity happens. A kitchen counter is the clearest case - an under-cabinet bar at 1,245 lumens and CRI 92 changes cooking more than any ceiling fixture can, because it lights the counter from in front of you rather than from behind your head.

Stage 4 is the evening rooms only. An ambient layer in a living room you sit in every night is worth far more than the same spend in a spare bedroom. A torchiere in a corner is the standard move, for the reasons in where to put a floor lamp.

Two things should reorder the list above, and both are about circumstances rather than lighting.

If you rent, buy things that leave with you. Bulbs, lamps, plug-in bars and clamp fixtures all move house. Anything screwed to a wall may not, and anything hardwired definitely does not. That is not a reason to accept bad lighting - it is a reason to spend the budget on the portable half of the list, which happens to be stages 1, 3 and 4 anyway. The framework is in can you change a light fixture in an apartment.

If you are about to redecorate, do lighting after paint, not before. Wall and ceiling color changes how much light comes back into a room by a large margin - a pale ceiling is the difference between an uplight working and not working. Painting after you have sized the lighting means re-sizing it.

Beyond that, work room by room rather than layer by layer across the house. Finishing one room completely gives you a reference for what "right" looks like, and it is far more motivating than having every room half done. The room pages are all in room-by-room lighting, and the three-layer framework each of them uses is in layered lighting.
