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

A 100 Watts bulb draws **0.90 Amps**.

## How many amps do LED work lights draw?

LED lights by their nature are low voltage but also relatively low current making them lower in power and more efficient that traditional incandescent bulbs and halogen downlights. Generally we are talking about **between 100 to 750 milli-amps** depending on the forward voltage required to turn on the LED.

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

Registered. Very simple as stated in this thread. watts divided by voltage = amps. IE 120 watts divided by 12 volts = **10 amps**.

## How many amps does a 50 watt LED light use?

A 50 watt bulb should pull about **4 Amps** from the transformer secondary.

## How many LEDs can be on a 20 amp circuit?

Up to **40 lights** can be put on a 20 Amp breaker.

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

It depends on the voltage you connect it to. For a 120 V supply, it is rated to be 200 Watt. R is 72 Ohms. I have **1.67 Amps**.

## How many amps does a 300w LED light use?

120 Volts x **2.5 Amps** = 300 watts (same thing)

## How much power does an LED bar use?

So how many watts does a good light bar have? Even though there are quite a few different factors that go into it, a good LED light bar should have a **minimum of 120 watts**, although 240 watts would be better in most situations. If you want to go overboard though, you can go all the way up to 800 watts or more.

## What size fuse do I need for a 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.
