150 Watt Led Light Bar Amp Draw

It was labelled as 100w light bar for a nominal 12v supply.

150 watt led light bar amp draw.

Each cfl or led bulb typically gives the same amount of light as a 60 watt incandescent bulb while drawing 10 watts or less which is equivalent to a current draw of 1 12 amp. 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. I calculated current draw at 8 3 amps 100w load. Thus a 15 amp.

Many switches would be able to handle that but if you are using say our 50 led light bar that has an amp draw of about 17 2 amps which may be too much for that little switch to handle. I got in a head spin with a light bar i bought for the car. Take an led 120 volt light bulb draws 12 watts. As a result you could end up overheating the switch melting the wires and reducing.

For example a 100 watt bulb in a 12 volt system will draw 8 3 amps 100w 12v 8 3a. In reality it drew 3 9 a which suggests a load of 49w. 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. The difference is significant especially for rvers who do a lot of dry camping.

Wattage to amperage conversions at 120 volts. Our lowest amp draw led light pod has an amp draw of about 1 4 amps. An example is an led 24 volt globe light that pulls 8 watts which draw 0 333333 amps. Depends on the size of the led light and the voltage applied.

Amp draw is a simple mathematical calculation. Divide the total number of watts by the system s volts. This video takes you step by step to quantify the amp draw of the two kinds of lights.
