How Many Amps Does 300 Watt Led Light Bar Draw

Equivalent wattage and amperage values at 12 volts.

How many amps does 300 watt led light bar draw.

The difference is significant especially for rvers who do a lot of dry camping. For example a 2012 7w bulb with a cree xt e chip can produce more light or lumen output than a 12w bulb with an older cree xp e chip. If your led lights bars draw a total of 1500 watts then i suggest a 150 amp fuse. This video takes you step by step to quantify the amp draw of the two kinds of lights.

For example if your led has a voltage of 3 6 and a current of 20 milliamperes it will use 72 milliwatts of power. To calculate an led s power use simply multiply the led s voltage in volts by the led s current in amperes. Older led chips found in older generation led bulbs from as recent as 2008 2010 produce less light per watt than the 2011 2012 led chips found in more modern led bulbs. Mr16 gu5 3 may be 120vac rated or 12vac not dc rated and may be protected with better cooling so that the free space above the lamp does not restrict the flow of convection cooling by a better design track socket or extension and not a cup back that restricts airflow or right at the.

Add up the wattage of everything plugged into the circuit and divide by the circuit s voltage to determine the total amperage draw on the circuit. Take an led 120 volt light bulb draws 12 watts. When dave connects incandescent bulbs to an amp meter they draw up to 1 6 amps but when led lights are used they only pull about 26 amps. When determining how many lights can be run on a circuit it is important to also account for all other electrical appliances plugged into the same circuit.

1500w 12v 125 amps but you should add a bit of a buffer about 20 more so a 150 amp fuse is perfect. The result measured in watts is the amount of power your leds use. If the light is operating at 110 volts and p i x e then i 300 110 or 2 5 amps.
