Yeah....flashlights are a focused beam as opposed to "all around" diffused lighting from household lamps.
That is why spotlights are rated by candlepower rather than lumens.
Generally if you go by 800 lumens equaling a 60 watt incandescent bulb you can get a good gauge.
The chart Biker posted is an excellent guide. I've found that due to the coloration of light given by LEDs that they APPEAR to be just a tad brighter than their incandescent equivalent. It's just due to their tint being slightly to the blue side of the color spectrum that gives this appearance. Blue and green are closer to the resonant frequency of the light spectrum which the human eye responds best to.
