Three lights cover childhood: a dimmable warm ceiling light for play and tidying, a wall-mounted reading light the child can reach from about age five, and a barely-there amber nightlight low in the room. Everything 2700K after tea-time, homework light separate and cooler, and every fitting either out of reach or too fixed to pull down.
A child's room runs the widest brightness range in the house — full light for Lego surgery at 4pm, near-darkness for the third reassurance visit at 2am — and it has the strictest client. The scheme below covers cot to teens with three fittings and two principles: warm evenings, and independence as soon as small hands can manage a switch.
The main light: warm, dimmable, and up out of the story
The ceiling light does the daytime heavy lifting — play, tidying, the floor-based archaeology of a six-year-old's carpet — so make it genuinely bright, but dimmable and warm (2700K), because the same fitting runs the wind-down hours. A flush fitting keeps it out of pillow-fight range. The Kaos earns its place here twice over: nothing to grab, and its temperature switch means the room can run warmer as the child (and the bedtime battles) mature.
Reading light: the independence machine
From the first bedtime books, a reading light the child controls changes the room's politics: their light, their switch, their decision to turn it off (in theory). Wall-mounted above the headboard beats a lamp on a flex — nothing to pull down, nothing to knock over, and the switch sits at exactly bunk height. The Defoe's aimable spot keeps the beam on the comic and off the ceiling, which matters when the room is shared.

Defoe Reading Spot · White
Recessed flush into the wall — nothing protruding, nothing detachable — with an aimable spot and a switch small hands manage easily. The bunk-bed-proof reading light.
The nightlight: dimmer than you think, warmer than you think
The nightlight's job is emotional, not optical — enough glow to make the wardrobe ordinary again, not enough to register as "lights on" to a sleeping brain. That means amber-warm (an 1800K bulb dimmed low is ideal; blue-white nightlights work directly against sleep), placed low and out of the direct sightline from the pillow. If the landing light does this job through a cracked door, a sensor fitting out there is often the better nightlight than anything in the room.
Homework happens on a different circuit
When desks arrive, give them their own light — brighter, cooler if you like (3500–4000K aids focus), and strictly switched off at wind-down so the room can change gear. The one absolute: no cool-white bulb in the main or bedside positions. The evening room stays 2700K — the same physiology as the adult bedroom, with higher stakes.
The safety list, briefly
LEDs throughout (cool to the touch); fittings fixed or out of reach for under-fives — wall and ceiling beat floor and table; short flexes routed behind furniture; and anything within grabbing height chosen on the assumption it will, eventually, be grabbed.
