Downlights Too Cold? How to Choose Between 2700K, 3000K and 4000K
Cold light and glare often get mixed up. Here is what kelvin means, how to get warmer light, and what a shade can and can't do.
Frequently asked questions
What is the difference between 2700K and 3000K?
2700K is a little yellower and warmer, 3000K a little whiter. Both count as warm light. 2700K suits living rooms and bedrooms, while many people prefer 3000K in kitchens and bathrooms.
Why does my light feel cold when the box says warm white?
"Warm white" is used for both 2700K and 3000K, so check the number. If the light still feels harsh at a low kelvin, the cause is often glare from the bare light source rather than the colour.
Does a shade over the downlight make the light warmer?
A little, but only a little. A shade like Lumeaglow is made to reduce glare, and it makes the light only slightly warmer. It does not replace a warmer bulb. For a clearly warmer light, you need a different bulb, a switch setting or a new fixture.
Can I change the colour temperature of built-in LED downlights?
Only if they have a colour temperature switch or smart control. Check the data sheet for your model. Without one, the colour is fixed.
