When purchasing LEDs for your facility, storefront, or home, one of the more important things to consider is your desired light temperature or color temperature. Color temperature can have a big impact on the visual appeal, and color reproduction of a space — facets which are particularly important for those choosing LED lights to accentuate products, or need a room to have a certain feel.

The Basics of Color Temperature

Color temperature values are related to physical light temperature values and are thus measured in degrees Kelvin. Kelvin is the base unit of thermodynamic temperature within the International System of Units. When related to color temperatures, an LED will typically range from 1700K and 9500K.

The reason why color temperatures are related to heat and light temperatures is due to how heat changes in color. For example, imagine starting a campfire or fire in a fireplace. Initially, the flames about the wood will emit a soft red or orange but the more the heat increases, the brighter or lighter it’ll get burning from orange to white and sometimes even blue.

Color temperatures are related to this change of heat or light temperature and are generally rated accordingly for commercial and residential usages:

Color Temperature 1700K to 3000K 3100K to 4500K 4600K to 7000K
Light Appearance Warm White Cool White Daylight
Ambiance Cozy & Calm Bright & Vibrant Crisp & Invigorating

Selecting the Right Light Temperature LEDs

When & When Not to Choose Warm White

  • Warm whites are an ideal choice for residences and businesses seeking to make people feel at ease. They offer a cozy and inviting atmosphere and are particularly great for accentuating wood and bricks.
  • Warm white light temperature LEDs would not be a good choice for a busy work environment as they may decrease productivity by affecting how comfortable employees might feel.

When & When Not to Choose Cool White

  • Cool white LEDs are also known as neutral light is a nice middle balance. This level of light evokes vibrancy and is a good choice in office buildings in which such lights can boost productivity and improve morale. It’s also a good choice for accentuating merchandise and for use in task lighting.
  • Being in the middle and, as its name suggests, neutral, cool white style light can make things feel a bit clinical. Thus, it tends not to be a good choice in areas where a certain mood is desired.

When & When Not to Choose Daylight

  • Daylight range lights are crisp and invigorating just as the sun shining on a clear, cloudless day. They are a great choice for warehouses, greenhouses, security lighting, and other areas needing bright and lively light.
  • However, due to daylight range LEDs evoking a more lively and invigorating atmosphere, they are not a good choice in residential situations or businesses like counseling or therapeutic companies in which owners are trying to evoke a more residential-like atmosphere.
