Fluorescent Light Bulb Color Temperature Chart

If proper color temperature is important avoid buying fluorescent and led bulbs that don t indicate the color temperature.

Fluorescent light bulb color temperature chart.

There are two standard measurements for the color characteristics of light. 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. Sometimes at when 4000k the temperature can be referred to as neutral white. You will find this color temperature in cooking kitchens retail stores and daytime offices.

At 3500k and up to 4300k you find fluorescent lights. Soft white 2700k 3000k bright white cool white 3500k 4100k and daylight 5000k 6500k. Warm lights are recommended for places where you need to. Color temperature is a description of the warmth or coolness of a light source.

Light color or color temperature is measured using the kelvin scale. This color begins as red in appearance and graduates to orange yellow white and then blue white to deeper colors of blue.

Virtually all light bulbs or lighting fixtures that come with bulbs included will reference on the package which kelvin color temperature is.

It is measured in degrees on a kelvin scale k and typically ranges from 2700 5000 degrees kelvin. 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. The higher the degrees kelvin the whiter the color temperature. Light bulb color temperature is represented in the unit of absolute temperature kelvin noted by the symbol k.

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. Compact fluorescent light bulbs typically last longer than incandescent bulbs and vary in color temperatures. How to choose the right kelvin color temperature. These lights are bright and offer no favor to the warm or cool side of the kelvin scale.

The range of color temperature. When a piece of metal is heated the color of light it emits will change. The surface temperature of incandescent light bulbs varies from 150 to more than 250 degrees whereas compact fluorescent light bulbs have a surface temperature of 100 degrees fahrenheit. 741 or 941 would indicate 4100k the color temperature is usually labeled on the bulb or the package.
