LED Lightbulb Info

The price of LED lightbulbs has dropped roughly 90 percent since their early days. LEDs use 80 to 90 percent less electricity than incandescent bulbs and last for years, saving you big cash and trips up the ladder.

Know your terms:

Replacement wattage:
It's the wattage of the incandescent bulb that the LED is meant to replace- a rough brightness equivalency.

Wattage:
The actual power used by the LED bulb. A typical household LED uses about 8 to 20 watts, so if a fixture says 60W max, you have plenty of capacity to spare.

Lumens:
The measure of brightness. The more lumens per watt, the more energy efficient the bulb is.

CCT:
Correlated Color Temperature is measured in kelvins (K) and describes the tone of light emitted. In general, use "warm" or "soft" white bulbs (3000K or below)  for bedrooms and living rooms: "cool" white (3100to 4500K) for bathrooms: and "daylight" (abouve 4600K) for outdoors or workrooms.

Dimmable: 
An LED bulb will work with a dimmer switch only if the package explicitly says so.
