The living room is the only room in the house that has to be four different rooms in a single evening: somewhere to talk, somewhere to read, somewhere to watch a film and somewhere to receive guests. One lamp on the ceiling cannot do all of that, and that is exactly why so many living rooms are badly lit. So we took ten lamps from ten manufacturers, each for a different job: a pendant over the seating area, a chandelier, a flush ceiling light, a reading floor lamp, a table lamp, a wall light, an LED strip, a panel, a recessed downlight and a track system. For each one we give the things that really decide how the room looks after dark: light output, colour temperature, CRI, how it dims and how long the warranty runs. Every number comes from the product record, not from a brochure. In a hurry? The table is enough. Want to know why your one lamp will never be enough — keep reading.
