# Quick Answer: How Many Amps Does A 40 Watt Light Bulb Use?

## How many amps does a 12 volt LED light use?

How much amperage does a 12v LED draw.

For instance, if each strip is rated at 48 watts, then the total draw of each strip would be: 48W / 12V = 4 amps..

## How many amps does a 150 watt light bulb use?

1.36 AmpsCurrent (Amps) drawn would be watts divided by supply voltage. In other words, at 110 volts you’d expect this 150-watt light to draw about 1.36 Amps.

## How many LED lights can I put 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.

## How many light bulbs can I put on a 15 amp circuit?

30 lightsYou can put up to 30 lights (based on 50 watt light) on a 15 amp breaker.

## What is a 40 amp breaker used for?

Double-pole breaker The 15-amp and 20-amp breakers often handle baseboard heaters, 30-amp serve water heaters and electric dryers, 40- and 50-amp are for electric ranges, and the 70-amp could serve a large air conditioner or a subpanel.

## How many amps is a 100 watt bulb?

0.90 AmpsA 100 Watts bulb draws 0.90 Amps.

## How many amps does a 60 watt light bulb use if your house is 120 volts?

In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of 240 Ω.

## How many amps does a light bulb use?

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.

## How can you tell the wattage of a light bulb?

Measure the current (in amperes)using an ammeter, then multiply by the line voltage. The result is the power in watts. Note that this only holds for incandescent or halogen bulbs.

## Can I use 100w bulb instead of 60w?

However, LED’s do not emit dangerous levels of heat. Thus, if your fixture says “not to exceed 60-Watts” but you want to use a 100-Watt equivalent LED bulb, this would be safe to do so. … For a 60-Watt fixture, you could use a 100W, 125W, or even 150W LED equivalent because they all consume under 60-Watts!
