Q: How many times longer does a LED or CFL last vs. an incandescent?
A: An ENERGY STAR-qualified LED bulb will last as much as 25 times longer than a comparable traditional incandescent bulb. An ENERGY STAR-qualified CFL lasts ten times longer than a traditional incandescent bulb that puts out the same amount of light.
Q: How exactly are these new bulbs better than traditional incandescent bulbs?
A: Traditional incandescent bulbs use a lot of energy to produce light. 90% of the energy is wasted as heat. That lost energy is money we are throwing away. ENERGY STAR LEDs use about 25% of the energy and last up to 25 times longer than traditional incandescent bulbs they replace. LED bulbs last significantly longer than traditional bulbs, so you won’t need to replace them as often, and will keep saving into the future.
Q: Will all older light fixtures accept LED bulbs? What if my lampshade connects right to the bulb?
A: Most older light fixtures with conventional, medium screw-based sockets will work with LED bulbs with E26 bases. When in doubt, take the bulb you are replacing to the store and ask for assistance. If your lampshade connects directly to the bulb, look for a replacement with a similar “bulb” shape.
Q: How do I choose which LED light to buy? What is my option to replace a 40-watt bulbs?
A: Look for the ‘wattage equivalent’ on the packaging. An incandescent bulb that uses 40 watts (40W) is comparable to an 8 watt LED bulb, which uses 32 less watts than the incandescent bulb while offering a comparable amount of light.
