hefner candle
Definition: A unit of luminous intensity defined by the light emitted by a Hefner lamp, which was the standard of light measurement in Germany for much of the 19th century.
Historyandorigin: Named after the German physicist Heinrich Hefner, this unit was widely used in Europe before being replaced by the international candle and later by the SI unit, the candela.
CurrentUse: The Hefner candle is no longer in use and has been replaced by more accurate systems of measurement.
funfact: The Hefner candle played a critical role in standardizing light measurements in Europe, particularly in scientific studies of light.
lumen/steradian [lm/sr]
Definition: A unit of luminous intensity per unit solid angle, representing the amount of luminous flux emitted in a particular direction.
Historyandorigin: Lumen per steradian is derived from the lumen (a unit of luminous flux) and steradian (a unit of solid angle).
CurrentUse: Commonly used in photometry, especially when describing directional light sources like projectors or flashlights.
funfact: This unit is key in measuring how light spreads in a specific direction, and is used for understanding light distribution in optical devices.

How to Convert hefner candle to lumen/steradian
1 hefner candle = 0.9000000001 lumen/steradian [lm/sr]
1 lumen/steradian [lm/sr] = 1.111111111 hefner candle
we use cross multiplication method
hefner candle → lumen/steradian [lm/sr]
1 → 0.9000000001
1.5 → ?( suppose x)
=>1.5*0.9000000001=1*x
by simplifying
x=1.3500000001
