What Light Temperature Suits Lumira? 2700 K, Not More

The Kelvin number on the bulb box decides whether your Lumira feels like a candle or a doctor's waiting room.

The number you're looking for sits in the top right corner of the bulb box. It's called color temperature and is measured in Kelvin (K). For Lumira, it matters more than wattage.

Lumira has a smooth white lampshade that spreads light across the whole room. The higher the number, the cooler and bluer the light. At 4000 K and above, the shade starts to look like an office ceiling panel, and that's not what you want.

What to buy

2700 K (warm white) is the safe choice. Honey-toned, calm, almost yellow. Ideal for a nightstand, the living room, and anywhere you sit in the evening with a book or a glass of wine. A Lumira at 2700 K feels like a ceramic lamp from the 1960s, just with an LED bulb inside.

3000 K is slightly brighter and works well if you also work in the room or use it during the day. Still warm, but easier to read by.

4000 K and above, skip it. Cold white kills the whole design impression. Lumira stops being a mood lamp and starts looking like emergency lighting in a hallway.

One more thing to watch: buy a bulb with frosted glass, not clear glass. A clear filament shines through the shade as a sharp bright dot and ruins the diffusion that is the whole point of Lumira. Feel free to go lower on wattage too: a 6 to 8 W LED is plenty, more will light the shade up into a flat white glare and lose the warm tint.

All Lumira variants take a standard E27 socket, which means you can buy the bulb at any hardware store for a couple of euros. Pick your temperature, plug it in, and in the evening it lights up exactly the way it should.
