To put it another way switching from an incandescent 60 watt bulb to a 60 watt equivalent led bulbs saves nearly 84 percent of the price.
Incandescent bulb vs led.
Bulbs needed for 25 000 hours.
Let s put cost aside for a moment and look at these lighting options based solely on quality and other important factors.
Bulb packaging now has a lighting facts label to inform you about the bulb s lumens wattage used lifespan and cost to operate.
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.
Led viribright watts used.
Leds require less wattage than cfl for the same amount of light.
Other ways to compare cfl vs.
Lumens for incandescent bulbs are.
Standard incandescent light bulbs can last only 1 000 to 2 000 hours depending on usage.
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.
Rather incandescent light again like leds tends to emit less light prior to total failure at the end of its useful life.
It would only take a 16 watt bulb to emit as much light as a 100 watt incandescent bulb and it would use only 140 kwh of energy over the year.
The led bulb is more than six times as efficient as the incandescent bulb it is replacing.
Cost less than led light bulbs.
Led vs cfl vs incandescent cost.
The electric cost would be just 21.
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.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
Oh and one led would last the entire year.
Cost of electricity 25 000 hours at 0 15 per kwh.
Use less energy than incandescent bulbs.
Average cost per bulb.
Examine the label of the led bulbs at the store.
Total purchase price of bulbs over 20 years.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
This is why led bulbs cost a little more than incandescent bulbs.
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.
