The color temperature rating is designed to give consumers a common metric to determine the color of the light output by a bulb. Most common bulbs and fixtures have a color temperature between 2700K and 5000K. The best way to think of the rating is the lower the rated temperature, the warmer (redder) the color of light. The higher the rated temperature the cooler (bluer) the color.
Varies by facility type and customer. However, there are industry recommendations on color temperature by facility type. One such recommendation for offices is a color temperature range between 3000K and 4000K. With most customers choosing either 3500K or 4000K as their color temperature.
Varies by industry and application
Yes, LED’s typically draw between 50% and 75% less energy than a comparable traditional light source.
DLC is an independent non-profit organization that provides standards to manufacturers of commercial lighting. These standards help to guide manufacturers to produce high quality lighting products that have been verified to meet energy efficiency standards and other metrics. A DLC rating is important in procuring utility rebates, as many require all bulbs and fixtures installed under their programs to have a DLC rating.
Energy Star is in the process of sunsetting its lighting program. There are many reasons for this, but the key reason stated by Energy Star is “With the Department of Energy’s (DOE’s) enforcement of a 45 LPW backstop for general service lamps, LED is the dominant lighting technology, and federal standards prevent the sale of traditional, inefficient lighting sources. As a result, there is no longer any risk for backsliding in efficiency and the limited remaining potential for increased efficiency across most lighting categories no longer justifies the ENERGY STAR lighting program.”
