3500k light color. Household fixtures are commonly found in color temperatures on the Kelvin scale of 2700K warm incandescent 3000K warm white halogen and 3500K household fluorescent. 3500K - Neutral White - Balanced friendly inviting The theory of circadian lighting informs us that the brain is most alert in the middle of the day when light levels move into the pure white areas of the spectrum. We see that it has a blue spike then not a whole lot of cyan.
The lower color temperatures before 3000K on the color temperature chart represent warm lights which appear more orangered like a firelight at the 2700K and became less yellowgold from 3000K to 3500KTo make it more clear the color temperature of the candlelight is about 2000K and Halogen lights are around 2800K. Heres the spectrum graph of a 3500K white light. Lamps with a mid-range color temperature 3500K to 4100K have a neutral or white appearance.
Color temperatures of more than 3500K are usually reserved for commercial 4000K hospital 5000K and up is a very bright white or other utility applications where ultra-bright light is needed direct sunlight is 4700K so imagine how bright a 5700K bulb would seem. When I was a kid we used incandescent lights in my house so lights around 3500K 4000K normal. The bright white color creates a fast-paced environment that encourages customers to eat quickly and leave which is beneficial for quick service restaurants.
The best light temperature for offices is between 3500 Kelvin and 5500 Kelvin. Low Kelvin below 3500K is considered warm white whereas above 3500K is cold white. The higher the Degrees Kelvin the whiter the color temperature.
Soft White 2700K 3000K Bright WhiteCool White 3500K 4100K and Daylight 5000K 6500K. The best light temperature for offices is between 3500 Kelvin and 5500 Kelvin. Warm Color Temperatures 2700K to 3500K Lights with color temperatures between 2700K-3500K are considered warm Most homes look best in warm-toned light in part because people tend to decorate homes in warm earth tonesreds oranges and yellowswhich warm light enhances.
The Range of Color Temperature of Different Light Bulbs. You can check out a study about the effect of lighting on the Circadian Rhythm and why so many apps exist to control your screen color temperature so you can get. Light bulb color temperature is represented in the unit of absolute temperature Kelvin noted by the symbol K.
