LED lighting power consumption calculations for mobile, marine, and off-grid electrical systems are the focus of this lesson — number seven in Nate's electrical system sizing series at EXPLORIST life.0:15 The core formula is: watts × minutes ÷ 60 = watt-hours.0:53 A single 2.5-watt 12-volt puck light run for 375 minutes (6 hours 15 minutes) consumes 15.63 watt-hours, equal to 31.25 amp-hours drawn from a 100 amp-hour 12-volt battery.2:19 Scaling to 10 puck lights running simultaneously raises the load to 25 watts total and 156.25 watt-hours per day.2:49 For LED strip lights, Nate uses a 32-foot Govee roll rated at 32 watts — one watt per foot — allowing proportional calculation when only a partial length is installed.3:46 For dimmer-controlled lights, he recommends skipping variable-brightness estimates and calculating at 100% brightness to guarantee sufficient battery capacity at any dimness setting.4:57 The next lesson in the series covers 12-volt water pump power requirements.5:25
