Lumens for incandescent bulbs are.
100 watt incandescent lumen output.
Examine the label of the led bulbs at the store.
On average an incandescent bulb produces around 14 lumens per watt compared to 63 lumens for energy saving compact fluorescents cfl and 74 for led bulbs.
In the table below you can easily see how much 100 watt in lumens is and which alternatives you can choose.
A 100 watt incandescent bulb gives off 1 600 lumens.

A similar lamp designed for 230 v would produce only around 12 8 lumens per watt and one designed for 30 volts train lighting would produce as much as 19 8 lumens per watt.

Energy saving bulbs such as compact fluorescent lamps and led bulbs that produce an equivalent lumens as the 100 watt incandescent bulb use only 24 to 25 watts of energy.
For example to replace a 100 watt light bulb for a led lamp the amount of lumens must be compared.
Are you looking for an energy efficient replacement for your 100 watt light.
If you prefer brighter light look for more lumens.
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.

Most of us have a preconception of how bright a 100 watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs.
Watts measure the electrical energy required to light a bulb while lumens are a measure of the brightness of the light produced.
Lower voltage lamps have a thicker filament for the same power rating.
40w equals 450 lumens 60w equals 800 lumens 75w equals 1100 lumens and 100w equals 1600 lumens.
Dimmable from 100 to 10 these bulbs have a 200 degree beam angle to cast light in a wide area.
To replace a 100 watt w incandescent bulb look for a bulb that gives you about 1600 lumens.
Replace a 75w bulb with an energy saving bulb that gives you about 1100 lumens.
For example a 100 watt 1000 hour 120 volt lamp will produce about 17 1 lumens per watt.
13 lumens per wattcfls.
Replace a 60w bulb with an energy saving bulb that gives you about 800 lumens.
