Light emitting diodes (LEDs)are the latest technology in the lighting world. Since LEDs are such a new technology, shop carefully.
Like fluorescent lights, you’ll want to take a close look at the color rendering index (CRI) and the color temperature of any LED.
- Color rendering index is a measure of any light source’s ability to render colors accurately. You want a CRI of at least 80.
- Color temperature, which is measured in kelvins, gives you an idea of what the light will actually look like. The higher the number, the bluer the light source. Incandescent light is around 2700K-3000K. That color temperature in an LED typically looks very natural in the home. Avoid LEDs that are much above 4000K unless you prefer the look of a very “cool” light. Do not buy an LED that is much above 4000K for your home.
