When selecting your new bulbs, be sure to take the colour temperature into account, they’ll help you to create different moods or perform different tasks. What is a Kelvin? In short, Kelvins are the measure of how cool or warm the light is and the Kelvin scale measures the colour tempe...

If you want to get technical, the color of light on the white light spectrum is called color temperature, and it's measured on the Kelvin scale. The lower the number, the warmer (yellower) the light. Your typical soft white incandescent is somewhere between 2,700K and 3,500K, so i...
Ever since Edison introduced the very first electric light bulb in 1879, we have seen everything in the same Soft White color temperature, measured at 2700K (Degrees Kelvin). The light created by these bulbs has been the standard for over 130 years, giving off a slightly yellow glow which...
The good news here is that CFL technology has improved a lot since EISA was signed into law in 2007. Today, you'll find a greater variety of color options, including bulbs rated at the low, yellow end of the Kelvin scale, and you'll have an easier time finding dimmable CFLs, too. ...
I am not sure how a bulb would filter light? I assume it means it is towards the cooler end of the lighting spectrum with less/no yellow and so would be like a daylight bulb. I found a pic which shows the Kelvin scale which is used to show how yellow the light from a bulb is....
The Kelvin Color Temperature Scale puts numbers to the color of light. Source: Lighting Tutor Different color temperatures have different uses and provide a different ambiance. In general, yellow light feels warmer and more relaxed while blue light feels cooler and provides more clarity and alertness...
A light bulb's color temperature refers to the way a bulb looks and feels. The temperature is measured on a scale of Kelvin degrees of 1,000 to 10,000. Typically, the higher the number, the more white a bulb appears. Warmer temperatures tend to be anywhere from 2000 to 3000K. They'...
The bulbs run a steep $90 a pop (though for scale, the Saucer Bubble and PH5 run $445 and $1,224 each) and bring a degree of technical complication: They're adjusted via a smartphone app. They can also be connected (though not color-adjusted) to a proprietary Philips Hue dimmer swit...
6 7 Previous Next CRI Consider selecting light sources (light bulbs) that have a high CRI (color rendering index) like clearly explained in the chart above. This metric though possibly changing to CQS shortly (color quality scale) is still extremely helpful in areas where the true color of ...
