LED lighting offers many benefits and features that were difficult, if not impossible, to offer with other lighting technologies. Many of the obvious benefits, such as substantial operating energy and cost reductions, longer life and lower overall heat generation are generally well known. Another feature that allows for dramatic appearance and productivity benefits, now and in the future, involves the color temperature of the light produced by LEDs.
Choosing the right color temperature can sometimes be difficult. These helpful tips will get you started in the right direction.
Light color is measured on a temperature scale referred to as Kelvin (K).
Lower Kelvin numbers mean the light appears more yellow; higher Kelvin numbers mean the light is whiter or bluer.
For a warm-yellow light, use bulbs marked 2700-2900K.
For a whiter light, use bulbs marked 3000-4100K.
For bluer white light, use bulbs marked 4200-6500K.
