The difference is 300 Kelvin, and that sounds like nothing. In practice you do see it: 2700K is the yellow light of an incandescent bulb, 3000K is a fraction whiter. At 3000K white stays genuinely white, while at 2700K it drifts towards cream.
Where you notice the difference
Not in a dark hallway. But certainly in the places where color matters:
- Kitchen. At 2700K vegetables look duller and a white kitchen cabinet looks beige. At 3000K the picture is right.
- Bathroom. At the mirror you want to see what you are doing. 2700K pulls your skin tone warmer than it is.
- With a white or gray interior. Cool materials turn dirty yellow at 2700K. With wood, terracotta and beige the opposite happens: those come alive at 2700K.
- Side by side. Two spots 300K apart in the same ceiling stand out immediately. On their own, almost nobody notices.
When to choose 2700K
Bedroom, seating area, hallway, and anywhere the evening matters more than the day. 2700K is the warmest setting that still passes as normal household light, and it is what most people unconsciously expect when they switch on a lamp — that is simply how an incandescent bulb worked.
Our catalog holds 22 products that can do 2700K. That makes it the most common fixed color temperature in the range.
When to choose 3000K
Kitchen, bathroom, study, and homes where you want one color throughout. 3000K is warm enough to stay pleasant in the evening and neutral enough to work by during the day. Twenty products can do this setting.
If you can pick only one value for the whole house, take 3000K. That is the setting that will not let you down in any room.
You do not have to choose now
A large share of our recessed spotlights has a CCT switch that lets you choose during installation. That is the most honest way to answer this question: put them up and see for yourself.
- Lesto — 2700K, 3000K or 4000K, plus 4 or 6 watts, €12.95
- Marlo — 2700K, 3000K or 4000K, Ø55 mm, €14.95
- Quaro — 2700K, 3000K or 4000K, 400 lm, €15.95
- Lyvo — 2700K, 3000K or 4000K, 500 or 700 lm, €16.95
- Ferro — 2700K to 5700K, 600 lm, €16.95
The little switch sits on the spot itself, so you have to take it out to change it later. Do it before you finish the installation for good: hang two, set one to 2700K and one to 3000K, and see in the evening which you prefer.
Dim2Warm takes the choice away
There is a third answer. 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 to 2000K, and the Warmo combines Dim2Warm with a CCT switch.
Then you have the brighter 3000K during the day and something warmer than 2700K by itself towards the evening. You do need a dimmable driver and a suitable dimmer for it.
In short
2700K for atmosphere, 3000K for atmosphere and visibility. If you are unsure, take 3000K or a CCT spot. What you should not do is use the two together in the same room. More about the settings individually in What light color is 3000K? and What light color is 2700K?
Is 3000K much whiter than 2700K?
Not much, but noticeably. On its own you barely see it; side by side in the same ceiling it stands out immediately.
Which of the two is better for a living room?
Either works. 2700K if the room is mainly used in the evening, 3000K if there is also work or reading done during the day.
Can I switch between 2700K and 3000K later?
With a spot that has a CCT switch you can, but you have to take it out of the ceiling to reach the switch.
