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
100 lumens=1257 candlepower from what I have found
It is a lot brighter than 50 candlepower and slightly less bright than 402 candlepower.

one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.

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).
60% of 15000000 = 60% * 15000000 = 0.6 * 15000000 = 9,000,000
Its about the Same as a 311 watt light bulb
