What light color is 3000K?

3000K is warm white light: a touch fresher than the yellowish light of an old incandescent bulb, but still clearly warm. It is the most chosen color temperature for living rooms, bedrooms and hallways, and the default setting on most of our recessed spotlights.

What that K actually means

The K stands for Kelvin, the unit of color temperature. The lower the number, the yellower the light; the higher, the bluer. It is a scale you read quickly once you know the anchor points:

• 2200K — candlelight, mood lighting
• 2700K — the light of an incandescent bulb, extra warm
• 3000K — warm white, homely but clear
• 4000K — neutral white, more businesslike
• 5700K and above — cool white to daylight

Color temperature says nothing about how bright a lamp is. That is lumens. Two 400-lumen spots at 2700K and 4000K give the same amount of light; one simply feels softer than the other.

Why 3000K is so often the right choice

2700K is very warm. Lovely in a bedroom, but in a kitchen or bathroom it quickly turns murky — white looks cream, and you see less clearly what you are doing. 4000K is the opposite: the light is bright and neutral, but in a living room it feels like an office.

3000K sits exactly in between. It is warm enough to stay pleasant in the evening and neutral enough to work by during the day. In a home you want to do with a single color temperature, this is the safest choice.

Choose 3000K now or later?

Our catalog holds 20 products at 3000K, and that is not the whole story. A large share of the recessed spotlights has a CCT switch, which lets you set the color temperature yourself during installation:

• Lesto — 2700K, 3000K or 4000K, plus a switch between 4 and 6 watts
• Quaro — 2700K, 3000K or 4000K
• Marlo — 2700K, 3000K or 4000K
• Lyvo — 2700K, 3000K or 4000K
• Ferro — 2700K, 3000K, 4000K or 5700K

That is worth more than it looks. You do not have to settle the question before the spots are in the ceiling, and you can pick a different setting per room without ordering a second type of spot. If you are torn between 2700K and 3000K, a CCT spot is the way to postpone that choice until you see the light in your own ceiling.

Dim2Warm: 3000K that moves with you

There is one more variant. With Dim2Warm, the color temperature drops as you dim, just as an incandescent bulb turned yellower when you turned it down. The Vigo runs from 3000K at full power down to 2000K at its lowest setting. The Warmo combines Dim2Warm with a CCT switch.

For a living room where the light may go low in the evening, that is the most pleasant option: bright 3000K during the day, warmer by itself at night. You do need a dimmable driver and a suitable dimmer for it — see the dimmer guide.

Do not mix them

The biggest mistake in a lighting plan is not picking the wrong color temperature, but using two of them in the same room. A ceiling with 2700K spots and 4000K spots mixed together stands out immediately: one half looks dirty yellow, the other blue. Choose one value per room and stick to it, including for any wall lights and free-standing lamps.

You can read more about choosing between the settings in the lighting guide or in the recessed spotlights collection, where each spot lists the color temperatures it can produce.
