A lumen is a unit of luminous flux. It is represented by the abbreviation 'lm'.
One lumen equals the amount of light emitted in a solid angle from a source that radiates to an equal extent in all directions.
3500 ANSI lumens is a measurement of the brightness produced by a projector or display device. It indicates how much light output the device is capable of, which is important for ensuring clear and bright images in various lighting conditions. A higher ANSI lumens value typically means a brighter image.
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.
From 20,000 to 23,000 lumens depending on the brand.Average figures:Incandescent: 10 lumens per wattHalogen 13 lumens per wattCFL (low-energy) 50 lumens per watt
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
A 150 watt halogen bulb will give off somewhere around 2000 lumens. These lights may give off up to about 2400 lumens.

Area can be used to find lumens. There are specific equations that are used to find lumens and area can be included in these equations. Plug the numbers into the equations and the amount of lumens will be found.
Approximately 15 lumens per watt for halogen, so 300 lumens.
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.

700 lumens
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
100 lumens=1257 candlepower from what I have found
To calculate the efficiency of a light bulb, you would divide the light output (measured in lumens) by the power input (measured in watts). This will give you the number of lumens per watt, which is a measure of how efficiently the light bulb converts electricity into visible light. The higher the lumens per watt value, the more efficient the light bulb.
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
It varies from about 600 to 1100 lumens. Typically the higher the lumens output, the shorter the lifespan of the globe. Have a look at this list of globes for purchase whih shows wattage and lumens: http://1000bulbs.com/category/75-watt-incandescent-standard-shape-light-bulbs/
