if old lightbulbs aren't burned out, is it even worth replacing them? many would say no, due to the many misconceptions about the benefits of light emitting diodes (leds). let's get to the bottom of these myths so you can make a more informed decision when it comes to switching to leds.

1. leds are too expensive

though they may have a slightly higher upfront cost than conventional bulbs, leds will more than make up for it with higher efficiency and a longer lifespan. that means you'll save more on your energy bills and won't have to spend money on replacement bulbs for years.

2. leds don't work in the cold

as it turns out, leds work even better in extreme cold than they do in excessive heat. very high temperatures can shorten rated life and damage components of all electrical equipment, but leds actually become more efficient and last longer when used in cold temperatures.

3. leds take a long time to light up

leds light up almost instantly. other bulbs may come on slowly after the switch is flipped and even flicker as they power on. leds, on the other hand, achieve full brightness almost immediately and can even be switched on and off continuously without shortening their lifespan.

4. leds can't be dimmed

today's dimmable leds and dimmer switches work together flawlessly. many dimmers were previously designed to work with incandescent and fluorescent bulbs, and led technology works a little differently. manufacturers have now caught up on both sides, and dimmable leds are a great and reliable option for home lighting.

5. leds don't give off any heat

an led's surface is cool to the touch, and it doesn't emit ultraviolet or infrared light. that leads many to believe leds don't give off heat, but in fact, the insides do get hot. about 20% of the total energy used by an led is lost as heat.

now that you have the lowdown on leds, you can upgrade your lighting to save money and energy. sounds like a bright idea, right? visit our energy efficiency page for more information and available resources to help you save money.
