The Difference Between Warm White, Daylight & Cool White LED Bulbs

Is warm white or cool white best for the living room, bedroom, and bathroom? Whereas warm light simulates ambient sunsets in the 1,000 to 5,000 Kelvin range, cool light is bright and clinical in the 5,000 to 10,000 Kelvin range. Create the ideal cozy atmosphere with relaxing warm light, and focus the attention in active areas with cool light. Let’s take a closer look at cool white vs warm white LED bulbs.

When you come to buy LED bulbs, you’ll have a range of colours to choose from that’ll enhance living spaces, set the perfect ambience and bring surrounding decor to life.

[EDIT: 8 Nov’ 2017 – For the latest information about colour temperatures, read “The different colour temperatures of LED lights and how to choose the best ones”.]

 

The most popular choices are Cool White, Daylight and Warm White and these colours are measured in Kelvins. The higher the Kelvin value, the whiter the light. Warm White offers between 2700-3200 Kelvins, Daylight sits between 4000-4500, while Cool White consists of 5000-6200 Kelvins. For more info on kelvins read here

Below you can see the difference between each one and where they’re best used:

Warm White

Warm white is perfect for creating a cosy atmosphere in areas you want to chill with friends and family. Most people choose this colour for their living room, bedroom or dining room where everyone is gathered together.

Cool White

Cool white complements contemporary and modern decor as it casts a fresh, clear glow. It’s brighter and more focused, making it a popular choice for use in bathrooms and kitchens.

Daylight

If you’re looking to create a natural effect, daylight is the colour for you. It mimics natural light and can be comfortably used anywhere in your home.

    I have 2 lamps akin to this SKU: FT-BATH-MR16 installed in the bathroom. They had halogen m16 50w which gave ample light albeit yellowish. I have tried some LED bulbs from another supplier which are daylight 3w, although they give sufficient light I don’t consider them to be “bright” enough ! Which of you m16 would you recommend please ?

    • Jack / LED Expert says:

      Hi Dave,

      Thanks for your question.

      If you want an MR16 with a brightness (lumen output) similar to that of a 50 Watt halogen, I’d advise the following; http://www.ledhut.co.uk/spot-lights/mr16-led-bulbs/7-5-watt-mr16-led-spotlight-45w-replacement.html.

      This is a 7.5W MR16 and produces up to 505 lumens, which will be substantially more than what the 3W spot has to offer.

      You have 3 colours to choose from; Warm White, Daylight and Cool White. I’d advise Daylight or Cool White, simply because they’re colours commonly associated with use in bathrooms (and they’re brighter than warm white and not yellowish).

      I hope this has helped. Let me know if there’s anything else I can help you with.

      Thanks,

      Jack.

    Hi, I have a dull megaman ceiling bulb. 6 watt LR1206dDGv2 47mA 2800k
    What do you recommend as a replacement

    Hi, I currently have Philips GU24 120V light bulbs and would like to replace them with LED daylight bulbs… What do you recommend?

    • Jamie / LED Expert says:

      Hi and apologies for the late response.

      We don’t currently sell GU24 LED bulbs. I did a quick Google search and couldn’t find anything suitable, although you can get adaptors on Amazon and eBay to convert the fitting to a more common fitting, which would give you more options if you’re wanting to switch to LEDs.

    I have been trying to learn more about LED lighting. I have been reading several different websites about the number range of kelvins in warm white, cool white, and daylight. Love the explanation with pictures on your website, but it seems to go against what I have found on other websites. You do show that the higher number of kelvins will show a bluish hue, but you call it cool white. Whereas the other websites I am looking at are referring to the higher kelvins is Daylight. Very confusing. Please advise.

    • Jamie / LED Expert says:

      Hi Lynda. I can’t speak for other sellers/manufacturers but they will decide what to label their bulbs in terms of daylight, warm white and cool white. If you’re comparing bulbs from different sellers always look at the Kelvin number, not what the colour temperature is called.

      You can see how we have labelled our bulbs according the Kelvin measurement here: https://www.ledhut.co.uk/blog/what-are-kelvins/

      Hope that helps.

  6. Dafydd says:

    This doesn’t seem to match the rating of most LED bulbs I see. Although your site doesn’t give the Kelvin value of your bulbs, other sites rate them as:
    Daylight ~ 6500 K
    Cool White ~ 4000-5000 K
    Warm White ~ 2700-3000 K

    This would suggest that “Daylight” is actually bluer (or “cooler”) than “Cool white” as it is higher up in the kelvin scale.

    I am looking for a light bulb for my bathroom. What sort of light bulb is best for putting on makeup in the bathroom yet is still energy saving ?

    • Jamie / LED Expert says:

      Hi Ikko,

      Cool white tends to work best in bathrooms, and all LED bulbs are energy saving so just go with the one you like best!

      Hope that helps.

    I am looking for LED lights to replace eight 32 watts T8 ceiling fluorescent lights (two floor light fixtures) in my sewing room. Should I use Cool white or Daylight LEDs to get the truest fabric color

    • Jamie / LED Expert says:

      Hi Wayne. Daylight is the most natural light colour, so will give the truest fabric colour.
