However because lumens per watt vary for both incandescent and led lights it s easier to use a wattage to lumens comparison chart.
100 watt incandescent light bulb vs led.
Led viribright watts used.
Life span of led vs.
Available in 40 60 75 100 watt equivalent.
Lumens for incandescent bulbs are.
Oh and one led would last the entire year.
Total purchase price of bulbs over 20 years.
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 difference is significant especially for rvers who do a lot of dry camping.
Average cost per bulb.
The electric cost would be just 21.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
Cost of electricity 25 000 hours at 0 15 per kwh.
These bulbs last longer and use up to 80 less energy reducing energy and replacement costs.
100w led light bulbs have an assortment of color temperatures that can affect the look and feel of your spaces.
Led vs cfl vs incandescent cost.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
Leds require less wattage than cfl for the same amount of light.
Bulbs needed for 25 000 hours.
Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens.
A 100 watt incandescent lamp that emits 1200 lumens of light has an efficacy of 12 while an equivalent 12 watt led bulb that emits 1200 lumens has an efficacy of 100 which is more than eight times higher than incandescent so use very less electricity while emitting the same amount of light.
Dimmable globe led bulbs designed for bathroom vanities or anywhere a globe bulb is required these bulbs produce light equivalent to a 40 watt incandescent bulb yet only consume 10 watts of power.
100 watt equal led light bulbs if you are still using 100 watt incandescent bulbs it s time to upgrade to 100 watt led bulbs.
Some of the common wattages vs.
When dave connects incandescent bulbs to an amp meter they draw up to 1 6 amps but when led lights are used they only pull about 26 amps.
