# How much power does a LED light bar use?

Contents

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 watts is a good LED light bar?

Lumens vs Watts, which is more important?

Lighting Type Watts Efficiency
Incandescent Bulb 60 Poor
CFL 14 Good
6″ LED bar 36 Excellent

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

IE 120 watts divided by 12 volts = 10 amps.

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

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

## How many amps does a 288 watt light bar pull?

Shouldn’t that fuse blow as soon as I flip the switch? Or is it more likely I ended up with a 288 watt light bar (96 3 watt LEDs) that pulls 24 amps…

## What is the most powerful LED light bar?

Even today when you look at who uses the best, newest, highest-binned LED chips, nobody uses anything better than Vision X. That’s why the brightest light bar in the world, the Vision X XIL-PX9010, goes for over \$2,000 online!

## How many LEDs can a 12V battery power?

So, a 12V battery wired to four 3V LEDs in series would distribute 3V to each of the LEDs. But that same 12V battery wired to four 3V LEDs in parallel would deliver the full 12V to each LED – enough to burn out the LEDs for sure! Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply.

## Do LED light bars need a relay?

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.

## Do LED lights pull more 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 is rated to be 200 Watt for a 120 V supply. therefore R = 72 Ohms. I = 1.67 Amps.

High Intensity LED Light Bar – 36, 3-Watt LEDs – 8208 Lumen – 9 Amp Draw (-Flood-Black).

## How many amps does a 30 watt LED bulb draw?

A 12V/30 watt supply translates into a maximum of 2.5 amps of current drain (12V x 2.5A = 30 watts). How many amps does a 4 foot LED light draw? The Feit 4′ LED shop lights draw about 0.3amps each according to the manufacturer.

## How many amps do 12 volt LED lights draw?

For example, a 120V LED system will pull 1 Amp in a 120 Watt system, while a 12V LED system will need to pull 10 Amps to power the same 120 Watt system.

## 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.

## How many amps is a light bar?

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.

## 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.
