P-LIGHT Running times
To calculate the operating time for battery-powered products, the "Law of Nature" applies to Ohms law and it cannot be changed or influencing.
For example, in a 24V system, 24W is equivalent to lighting 1A in power sockets. I.e. in this case you get approx. 1 hour of lighting per battery Ah, (Note, applies to fully charged batteries in good condition at +20°C).
Ah x V/ W = h
Ah = Battery ampere, V = Volt, W = Power socket in Watt.
