300w Led Light Bar Amp Draw

I got in a head spin with a light bar i bought for the car.

300w led light bar amp draw.

The fuse rating should not correspond to the wire size but instead to the maximum current expected on that wire. Therefore the power of the led light is proportional to voltage and or current such that a device may have a low voltage but may still draw a very high current and have high power consumption. These 50 led light bars are ip 67 waterproof rated led lights. If your led lights bars draw a total of 1500 watts then i suggest a 150 amp fuse.

1500w 12v 125 amps but you should add a bit of a buffer about 20 more so a 150 amp fuse is perfect. The current i in amps is equal to the power p in watts divided by the line to line voltage v in volts multiplied by the power factor pf multiplied by the square root of 3. The drl or atmosphere light is not as bright as the main light bar but it can be light up in the place where there is light on and will not make glare to the oncoming vehicles. 50 inch led light bar with 300w led power and our lifetime warranty.

Although led lights are more expensive than incandescent bulbs they last so much longer eventually paying for themselves. Depends on the size of the led light and the voltage applied. An important consideration for rving families with young children is that incandescent bulbs can get dangerously hot while led lights remain cooler to the touch. I calculated current draw at 8 3 amps 100w load.

In reality it drew 3 9 a which suggests a load of 49w. For three phase ac circuits where the line to neutral voltage is known the formula to convert watts to amps is. For example the traditional 50w dichroic halogen downlight is only 12v ac but draws 4 167 ampres. This 50 inch led is a dual row led light bar has 300 watts of led power and carries an average life of 30 000 hours.

It was labelled as 100w light bar for a nominal 12v supply. When wiring led light bar relays or switches fuse all positive side wires such as from the positive battery terminal to the light bar switch. Take an led 120 volt light bulb draws 12 watts. An example is an led 24 volt globe light that pulls 8 watts which draw 0 333333 amps.
