LEDs use about one-fifth the power for the same amount of light output. So for your light bar, it would consume one-fifth of the current, i.e. 0.2 amps from a 120 VAC source, or 2 amps from the car battery. Check your light bar specifications, though, because efficiency varies a lot.

## How many amps does a LED light bar use?

55W LED lights are usually in 4-5 amp range. You can also use a high current meter.

## How many amps does a 120 watt LED light bar draw?

watts divided by voltage = amps. IE 120 watts divided by 12 volts = 10 amps. you can use this as a good reference for switching and if you need a relay.

## How many amps does 300 watt LED light bar draw?

So thats 300 watts. 300watts÷12 volts= 25 amps.

## How do I know what AMP my LED is?

A simple formula for calculating amps is to take the watts and divide that by the volts. So, for instance, if the wattage of the lighting fixture you’re working with is 60 and the volts are 12, divide 60 by 12 and you will get five, which are the amps.

## Do LED lights draw less amps?

You’ll find out why LED lights draw less from your battery while providing the same amount – or even more — light than the old incandescent ones. … 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.

## How many amps does a 200 watt LED light draw?

It depends on what voltage you connect it. It is rated to be 200 Watt for a 120 V supply. therefore R = 72 Ohms. I = 1.67 Amps.

## What size fuse do I need for LED light bar?

A 10 amp fuse will protect the circuit. The 16 gauge wire will handle 10 amps in the length of wire that you will be using. The switch is rated for 20 amps. So, the 10 amp fuse will protect the circuit from overload.

## Do I need a relay for an LED light bar?

A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. … If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.

## What gauge wire should I use for LED light bar?

LED Lights are expensive and in all cases should be protected against early burnouts. OPT7 Wiring Harnesses achieve this by using silicon infused 16 American Wire Gauge (AWG) cables that better control against voltage spikes and heat. The last line of defense against is the included relay and fuse.

## How do you aim LED light bars?

To aim LED light pods equipped with a flood beam you can either have them both facing straight forward. Or you can use them as LED ditch lights by having them facing straight but slightly outwards to increase the amount of LED light that is on the side of the road.

## How many amps does a 18w LED draw?

About this item. Light produces 1400 lumens of bright light while drawing only 18 watts @ 1.4 amps. Six 3 watt LEDs producing 233 lumens each and produce a wide 60 degree flood beam.

## How many amps does a 100 watt LED light bulb draw?

At 120 volts, the most common household current in the United States, a 100-watt light bulb draws 0.83 amps. To calculate the amperage of a light bulb, one must divide the number of watts by the volts powering the circuit.

## How many amps does a 100 watt LED light bulb use?

A 100 Watts bulb draws 0.90 Amps.

## How many LED lights can be on a 15 amp circuit?

Breaker Limitations

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. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
