In this video, Scott Caron, master electrician for Ask This Old House, deciphers the information on a lightbulb label.
1. Scott discusses lumens, which describe the brightness of a light.
2. Watts measure power consumption. The higher the wattage, the more money you pay for lights you use.
3. Color temperature is measured using the Kelvin scale. The lower the number, the warmer the light will look. The higher the number, the cooler the light will appear.
4. Some fixtures include integrated LEDs, which means no lightbulb to change at all.
