Look for energy star approved leds.
Led lights vs incandescent bulbs.
Bright led flood lamps use only 11 to 12 watts while creating a light output comparable to a 50 watt incandescent bulb.
Available in standard edison bases these bulbs are used as area lighting for rooms porches reading lamps accent lamps hallways and low light applications where lights remain on for extended periods.
Use less energy than incandescent bulbs.
Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors.
But when compared to their led counterparts life expectancy of an average led bulb is quoted as 30 000 to 50 000 hours which is almost 25 times of incandescent bulbs.
What does that mean.
For example a 4 pack of philips 60 watt equivalent soft white led bulbs costs about 12.
Other ways to compare cfl vs.
If this is a concern check the lighting facts label for the light appearance information.
In this style led bulb clusters of leds are covered by a lens which spreads the light over a wider area like standard incandescent bulbs.
How to understand this table look at the lumens brightness in the far left column then compare how many watts of power each light bulb type requires to produce that level of.
As a comparison a 100 w incandescent bulb will produce the same brightness of a 16 watt led bulb more than one fifth of required energy.
Led bulbs use more than 75 less energy than incandescent lighting.
Rather incandescent light again like leds tends to emit less light prior to total failure at the end of its useful life.
For centuries the incandescent light.
Initially led bulbs cost a lot more than old fashioned incandescent bulbs but now have dropped in price.
Let s put cost aside for a moment and look at these lighting options based solely on quality and other important factors.
At low power levels the difference is even larger.
Here are some pros and cons of cfls vs.
If your household electricity only powers a single light bulb you will pay 5 times less electricity bill if that bulb is an led instead of an incandescent bulb.
At low power levels the difference is even larger.
Summary of led vs.
Incandescent lights similar to led do not generally flicker and or cycle on and off as the bulb reaches the end of its useful life.
Cost less than led light bulbs.
