I don't believe that there is such a thing as an 'ampere per lumen'. An ampere is the SI unit of current, whereas the lumen is the SI photometric unit for luminous flux. There is no direct relationship between the two.
1 lumen = 1 candela per steradian.1 candela = 1/683 watts per steradians (assuming 540nm light wavelength).Assuming that the light is collected from a single steradian:1 Lumen = 1 Candela -> = 1/683 Watt -> Watt = 683 Lumens1 Joule = 1 Watt per Second -> Watt = Joule/SecondHence:683 Lumen = 1 Joule/SecondUnder the above assumptions1 Lumen = 1/683 Joule/Second
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.
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.
because lumen carries biochemical processes for the cells.
There are 1000 milliwatts per lumen.
there is 5 lumen per hour in 1 joule
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.

The scientific name for bighorn sheep is Ovis canadensis.
Double-lumen PICC lines come in two colors. Red is the blood access lumen or arterial lumen and blue is the blood return lumen or venous lumen. Despite the names, neither lumen is leads to an artery, but both lead into a vein.
A sheep belongs to the genus "Ovis."
The species name for a ram is Ovis aries.
One lux = one lumen per square metre See link for more detail.
