the lumen is bright
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.
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.
one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.
Cannot be converted as the dimensions of the units do not match. You can however convert candlepower to lumen/steradian.
A lumen measures the total amount of visible light emitted by a source in all directions. On the other hand, a candela measures the intensity of light emitted in a specific direction. In simpler terms, a lumen tells you how bright a light source is overall, while a candela tells you how bright the light appears in a particular direction.
A lumen is a unit used to measure the total amount of visible light emitted by a source, like a light bulb or flashlight. It indicates how bright the light appears to the human eye. The higher the lumen value, the brighter the light.
