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.
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.

There is no direct conversion because they are used to measure two different things. Radiometric units are used to measure radiant energy across the entire spectrum, whereas photometric units are used to measure visible light as preceived by the human eye. As the eye's sensitivity varies across the visible spectrum (being most sensitive to green light, and least sensitive to red and violet light), the conversion between the two systems of measurement varies according to wavelength at which it they are being compared.

Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
You cannot, it defies gravity
In basic medium using photometric method......

yes photometric glasses are available, turns dark under uv rays.
