A 50 watt incandescent bulb is about 650 lumens.
Bright
250 lumens is approx the same, as you would get from a 20w household lightbulb.
Its about the Same as a 311 watt light bulb
It is equivalent to a 75 watt incandescent bulb
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.

one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.
High Bright: 1700 Lumens Eco Mode: 1360 Lumens http://www.infocus.com/Support/Products/Projectors/IN24.aspx
This is very bright for indoor lighting, the equivalent of about 350 watts of incandescent lighting, or a 65-watt and 42-watt CFL pair (4200 and 2700 lumens respectively).

it is hard to describe by words, why not to buy an infinite bright flashlight to compare. I know a flahslight with displaying lumens. It is DDT40 imalent. from 5 lumens to 4000 lumens you could find a way to compare gradually. by the way, one lightening candle is a lumens.
Mitsubishi HC3900 with 3000 ANSI Lumens....best!
The 3M 2000 has a brightness of 1,600 lumens, which should be bright enough even in moderate daylight.
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
