a measurement of the amount of visible light.
Answer
A 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.

How much candle power in 360 lumen?
Lumen and candlepower are not the same thing. Lumen measure the of light surrounds, like you would light a room with a lamp. Candlepower measures the light in a beam, like a flashlight beam.

What is brighter 2000 lumen watt bulb or a 1500 lumen bulb?
This question is ill posed. Lumen is a unit of measure for how much light comes from the lamp Watt is a unit of measure for how much energy is used by the lamp If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb. I think the relation ship between lumen and watt is something like: Incandecent bulbs are 15w/lumen Flourecent bulbs use 40w/lumen LED bulbs are 70w/lumen The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter). Incandescent bulbs have a maximum luminosity of 52 lumens/watt. Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes) LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.
