Architect Lauren Adams and general contractor Jeremy Baker say cool temperatures have a blue glow, while warm temperatures have a soft, yellow tint. Warm temperatures (1500K-4000K) work better in cozy rooms like bedrooms, while cool temperatures (4000K-6500K) are better for high-focus spaces like offices.

   Candlelight (1500-2000K) This is a dim, yellowish temperature that creates similar lighting as the flame of a candle. It’s the perfect bulb temperature for creating a cozy atmosphere. A lower, candlelight temperature is ideal for intimate or relaxed spaces where you don’t want any harsh lighting. Plus, candlelight lighting is better for the environment because it conserves energy. It also promotes healthier sleep patterns by preserving healthy levels of melatonin.

   • Best for: Bedroom and living room lamps

   Warm Glow (2200-2700K) Like the candlelight temperature, this is a dim and warm light that provides a cozy vibe. It is slightly brighter than candlelight, but it still doesn’t create a harsh light. You might use this temperature for a comfortable but somewhat more energized atmosphere. This is the recommended temperature for outdoor lighting since it reduces light pollution.

   • Best for: Bedrooms, patio lighting

   Warm White (2700-3000K) Warm white produces a soft, yellow glow that’s brighter than a warm glow or candlelight. It’s warm enough to create a relaxed ambiance, but bright enough to illuminate a room. Adams and Baker often opt for a softer tone for lighting. This is a great choice for relaxed in-home lighting.

   • Best for: Living rooms

   Soft White (3000-4000K) Soft white bulbs emit a warm yellow-white glow. This temperature starts to move away from the cozier, relaxed light of the warmer bulbs. Adams and Baker say this is a good temperature for a residential environment. It’s the ideal temperature for high-traffic areas in your home.

   • Best for: Kitchens, bathrooms, hallways
5.

   Cool or Bright White (4000-5000K) Cool white light bulbs give off a bluish white color. This is harsher lighting and probably isn’t what you want in your relaxed living space. Typically, this color temperature is better for areas where you need to get tasks done because it allows you to see clearly and focus better. Plus, the higher color temperature creates a more energetic atmosphere.

   • Best for: Offices, garages, classrooms

   Daylight (5000-6500K) “Daylight bulbs end up looking somewhat blue,” note Adams and Baker. This temperature has a very cool glow that is often too harsh for residential spaces. You’ll usually see daylight lighting in larger, public spaces where high visibility is required. Avoid daylight lighting in the home to maintain healthy melatonin levels and a more consistent sleep schedule.

   • Best for: Hospitals, warehouses, retail spaces

What is color temperature?

1. 
   Color temperature is how warm or cool a light source is. A lower color temperature produces a warmer yellow-red glow, while a higher color temperature produces more of a bluish-white color. Different color temperatures work better in different spaces. For instance, you can use warmer light to make a room cozier, or cooler light to improve focus and alertness. The higher the color temperature you use, the harsher the light will be.

What is the Kelvin Scale?

1. 
   The Kelvin scale measures color temperature in degrees Kelvin. The Kelvin scale starts at zero and goes up to 10,000K for lighting. As you move up the Kelvin scale, the light’s color gets cooler. This means lower degrees Kelvin produce a warmer tint, while higher degrees Kelvin create a cool, blue tint.

   • The Kelvin scale doesn’t measure the brightness or the heat that a light source produces—it only refers to the color of the light. Brightness, or light intensity, is measured in lumens.
   • Certified color specialist Juli Roland points out that “you can see the color temperature [of bulbs and LEDs] listed on the package as the Kelvin rating. A higher temperature of 6,000 means a cooler, bluer light. At the other end, 2700 produces a more amber light. Those who don’t like a yellow cast to a bulb should look for something between those two ranges.”

How to Choose the Right Color Temperature

   Use cool temps for functional spaces and warm temps for living spaces. The room’s function and use can help you determine what color temperature is best. “Utilitarian areas such as laundry rooms, bathrooms, and kitchens are often cooler temperatures, whereas bedrooms and living spaces have warmer lights to create a cozier feel,” says DIY specialist Sarah Fogle.

   Select a light color temperature that complements your interior design. Warmer color schemes (taupe, gold, orange, red, etc.) pair nicely with warmer color temperatures like candlelight and warm glow. On the other hand, cooler color schemes (white, silver, blue, purple, etc.) and minimalistic designs tend to work better with cooler lighting like warm white or cool white.
3.

   Choose colors that reflect the ambiance you want to create. If you’re going for a more relaxed vibe, choose a warmer light temperature (lower degrees Kelvin). “A nice warm white, which is 2700 to 3000K, is typically what we'll use in a residential environment,” Adams and Baker add. If you want a more focused, alert energy, opt for a cooler, higher-Kelvin light temperature.
