Fluorescent Light Bulb Color Temperature Chart

Color temperatures higher than 3500k are typically used for commercial and hospital applications as the light is bright and has a bluish daylight cast that can be harsh for home interiors.

Fluorescent light bulb color temperature chart.

Leds are available in warm colors low k to match the yellowish light of incandescent bulbs but you can also choose cooler colors high k with whiter or bluer light. Color rendering index cri a term used to describe the extent to which an artificial light source is able to render the true color of objects as seen by natural outdoor sunlight which has a cri of 100 and color temperature which expresses the color appearance of the light itself. Virtually all light bulbs or lighting fixtures that come with bulbs included will reference on the package which kelvin color temperature is. You will find this color temperature in cooking kitchens retail stores and daytime offices.

A color temperature of 2700 3600 k is generally recommended for most indoor general and task lighting applications. Soft white 2700k 3000k bright white cool white 3500k 4100k and daylight 5000k 6500k. Light color or color temperature is measured using the kelvin scale. Good for areas that require soft lighting like dining areas.

Kelvin color temperature scale explained the kelvin color temperature scale is used to describe the way various light temperatures appear visually. It is measured in degrees on a kelvin scale k and typically ranges from 2700 5000 degrees kelvin. Household fixtures are commonly found in color temperatures on the kelvin scale of 2700k warm incandescent 3000k warm white halogen and 3500k household fluorescent. The higher the degrees kelvin the whiter the color temperature.

These lights are bright and offer no favor to the warm or cool side of the kelvin scale. But task lighting may. In such cases the closest possible match is made and the color is described as correlated color temperature. There are two standard measurements for the color characteristics of light.

An octron t8 fluorescent lamp with a color temperature rating of 4100k for example has a color appearance similar to that of a blackbody heated to 4 100 kelvin 3827 celsius 6920 fahrenheit. 2700k color temperature of an incandescent bulb very soft yellow and orange color. Light bulb color temperature is represented in the unit of absolute temperature kelvin noted by the symbol k. The lower color temperatures before 3000k on the color temperature chart represent warm lights which appear more orange red like a fire light at the 2700k and became less yellow gold from 3000k to 3500k to make it more clear the color temperature of candlelight is about 2000k and halogen lights are around 2800k.

At 3500k and up to 4300k you find fluorescent lights. Color temperature or descriptions are usually on the package or the base of bulb. Color temperature and color descriptions may differ slightly between bulb manufacturers. The three primary types of color temperature for light bulbs are.

Fluorescent light colors are determined by the selection of the phosphors inside a bulb.
