Luminous Efficacy: Lumens to Watts Conversion
Different light sources emit different amounts of visible light using the same amount of power. Luminous efficacy is a measure that shows how well a light source converts one type of energy, usually electricity, into visible light.
Luminous efficacy is a ratio of luminous flux (given in lumens) and power (given in Watts) and is written as "lm/W." In short, more energy-efficient light sources will provide more lumens for the same amount of power.

How to Convert Cold Cranking Amps (CCA) to Amp Hours (Ah)
Conversion between Cold Cranking Amps (CCA) and Amp Hours (Ah) is not a direct one for one very simple reason: Cold Cranking Amps describe the ability of the battery to provide strong currents required for starting/cranking of internal combustion engines, usually for 30 seconds, while Amp Hours (Ah) describes the capacity of the battery and its ability to provide certain current for, usually, 20 hours.
Basically, Cold Cranking Amps (CCA) and Amp Hours (Ah) both describe the capacity of the battery and its ability to provide current for some time - they are just two extremes of battery usage.
