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