Did you know that the average home has about 35 light bulb sockets, and that in most homes, more than 50% of these still contain inefficient lighting?
Generally more expensive than other lighting options, ENERGY STAR® LEDs save money because they use at least 75% less energy than incandescent lighting and last a minimum of 15,000 hours, or 15 years based on average household use.
That life span is about 15 to 20 times longer than incandescent lighting, and about three times longer than CFLs.
A few tips in selecting the ideal bulb:
ENERGY STAR® LEDs usually have a rating to help you compare bulbs to your old incandescents, but the best way to determine how much light a bulb will offer is to look at the lumens rating. The more lumens, the brighter a bulb.
"Regular" light bulbs have another name — A19. That's the standard light bulb size and base that will fit in most fixtures and lamps. But you can get ENERGY STAR® LEDs for all kinds of fixtures, including globe vanity lights, recessed track lighting, and outdoor lights.
Colour temperature is what determines the colour of the light — the warm yellow-white we know from traditional light bulbs, all the way to the cool blue-white you can find in white LED holiday lights. Colour temperature is measured in degrees Kelvin, listed on the package.
