Bulbs for domestic use are available between 3 watts and 100 watts. Bulbs used in large areas such as theatres and street lighting can be up to 2 kilowatts.
AnswerA lamp doesn't 'use' power, it uses energy. Power simply tells you the rate at which it consumes energy. So, you can ask how powerful a lamp is, but you can't ask how much power it uses!

How much power does a 5 watt bulb use?
The bulb uses 5 watts of power.
How much power does a travel humidifier use?
a travel humidifier can use a lot of power. a normal house light bulb uses less power but the travel humidifier can use a maximum of 300 to 500 watts. This can be used to make the place humid.
Can you use an inverter on a 1500 watt sodium bulb?
You can as long as the rating of the inverter supports the 1500 watt power requirement at the operational voltage of the bulb. There may be a surge at start-up of the bulb so that has to be taken into account.
What equation would you use to calculate how much current in AMPs is required to achieve the full 100 to output from a volt bulb?
The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
How much electricity does a scalextric use?
A typical Scalextric set uses about 15-20 watts of electricity when in use. This is equivalent to the power consumption of a small LED light bulb.
How much power does a 5 watt bulb use?

What is the power rating of lights?
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
How much power does a light bulb use when it is turned on?
When a light bulb is turned on, it uses a certain amount of power, measured in watts. The power consumption of a light bulb can vary depending on its wattage, with higher wattage bulbs using more power. For example, a 60-watt bulb uses 60 watts of power when turned on.
What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
How much power does the 3M 2000 Overhead Projector use?
Due to the bright bulb, the 3M 2000 overhead projector can use a substantial amount of power and is not, unfortunately, Energy Star rated.
