Led light bulbs vs incandescent wattage.

At low power levels the difference is even larger. 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. Led bulbs use more than 75 less energy than incandescent lighting. The more watts the brighter the bulb.

Since most household bulbs are 40w 60w. A 40 watt equivalent led bulb consumes only 6 to 8 5 watts. Bright led flood lamps use only 11 to 12 watts while creating a light output comparable to a 50 watt incandescent bulb. A standard 60 watt incandescent bulb puts out about 820 lumens.

In fact a 60. One of the better cfls on the market the ge reveal bright from the start light bulb uses 15 watts to produce 740 lumens. That s a nice improvement. If your socket says not to exceed 60 watts it is referring the dangers of high heat output associated with incandescent bulbs.

Another advantage of leds is the hassle factor leds last a lot longer than a regular bulb. That rule doesn t apply to led bulbs though. Cost of electricity 25 000 hours at 0 15 per kwh. An led that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts.

Bulbs needed for 25 000 hours. That bulb has an efficiency of 49 33 lumens per watt. Wattage and brightness comparison incandescent vs cfl vs led the task of choosing a replacement bulb only by its wattage is no longer an easy task as was in the past when incandescent bulbs were the only option and everyone understood the bulb brightness by its wattage like 60 watt 80 watt or 100 watt. Click the equivalent wattage in the lumens vs.

For example if you typically purchase 60w incandescent bulbs which produce about 700 800 lumens consider purchasing a lower energy alternative like a 42w halogen bulb 12w cfl or even a 10w led bulb to achieve the same brightness. The led equivalent of a 60 watt a19 bulb consumes only between 9 and 12 watts and provides about the same light output measured in lumens. Average cost per bulb. Total purchase price of bulbs over 20 years.

However because lumens per watt vary for both incandescent and led lights it s easier to use a wattage to lumens comparison chart. 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. When you see a label say 100 watt led equivalent that does not mean that the bulb actually uses 100 watts it means that it produces an amount of light equivalent to a 100 watt incandescent bulb.

This can be calculated if you happen to know your bulb s lumens per watt using this equation. Lumens watts x lumens per watt.
