one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.
the lumen is bright
If you refer to the energy cost, that doesn't make sense. Lumen means how bright something is - the actual cost will depend on how long you keep a bulb on; in other words, you would get dollars per kilo-lumen per hour, for example - not just dollars per kilo-lumen.
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.
Lumen measures the brightness of light, while kelvin measures the color temperature of light. Lumen indicates how bright a light source is, while kelvin indicates the color appearance of the light, such as warm or cool.
Cannot be converted as the dimensions of the units do not match. You can however convert candlepower to lumen/steradian.

A 300 lumen light is considered moderately bright and is suitable for tasks like reading, illuminating small spaces, or providing accent lighting. For comparison, a standard 60-watt incandescent bulb typically emits around 800 lumens, so 300 lumens would be about one-third as bright. This level of brightness is ideal for areas where softer light is preferred, such as bedrooms or cozy living rooms.
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
a measurement of the amount of visible light.AnswerA lumen is the photometric SI unit for luminous flux -i.e. the rate at which an object emits visible light. By 'visible light', we mean electromagnetic energy perceived by the human eye, and the lumen is based on the frequency of green light, to which the human eye is most sensitive.
Lumen
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
Typically power leds operate as 1-2 watt units. 50 watt is a little excessive for a single led: it would have to be an array. The light output that can be achieved in normal use appears to range from 80-120 lumen/watt, so I guess the answer would be something like 4000-6000 lumen!
