This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).
Bright
250 lumens is approx the same, as you would get from a 20w household lightbulb.
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).
Its about the Same as a 311 watt light bulb
It is equivalent to a 75 watt incandescent bulb
A 400 watt Mercury vapor light bulb produces roughly 23,000 lumens. In comparison to a 400 watt metal haloid and or high-pressure sodium, not as good. Metal haliod and high-pressure sodium produces 30,000 lumens.
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.
A 50 watt incandescent bulb is about 650 lumens.
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!
