It depends on how many Milliamp you push the 1w led. Most 1w leds are not 1w of power but less, so that they dont burn out fast. So the answer would not be 1w but truely less than 1w.

How do the types of light bulbs compare?
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
What is a lumen How does it relate to watts?
A lumen is a unit of luminous flux, which is the amount of light emitted per unit time. A watt is a unit of power (such as electrical power), which is the amount of energy consumed per unit time. Light bulbs have ratings in watts, which measures how much electricity they use, and lumens, which measures how much light they give off. For the same kind of bulb (incandescent, fluorescent, LED, etc.), a bulb with a higher wattage will produce more lumens. However, a 10-watt LED or compact fluorescent bulb may produce more lumens than a 40-watt incandescent bulb.
What is The electrical power used by light bulbs measured in?
Electrical power is measured in watts (W), just like any other type of power.Power is the rate at which energy is used. Energy is measured in joules (J), though utility bills usually measure energy using kilowatt-hours (kW·h) instead. 1 kW·h = 3,600,000 J.
How much does a 9 watt led light bulb cost to run?
The average for america is about 18 cents per kilo-watt hour, 0.18, multiplied by the 9 watts it consumes, 0.009 because we are using KILO-watt hours, to give you a grand total of: 0.162 Cents per hour to run
How bright is 950 lumens?
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
A LED light of 3 watts gives off the same amount of light as an incandescent bulb of 45 watts This means that the LED light.?
A 3 watt led light is not the same as a 45 watt bulb. A led light is a lot brighter.
What is the highest watt led light torch available?
The general amount of watts for an LED light torch is 3 watts.
How many watt does an exit light use?
If the exit fixture uses a LED lamp it will have a 1 to 3 watt rating. If it is a incandescent bulb, each lamp will draw about 25 watts each.
How many lumen will a 100 watt incandescent bulb produce?
Incandescent Watts...... . ..CFL Watt range... . . ... .. Lumen Range 406075100150 8 - 1013 - 1818 - 2223 - 2834 - 42 450890121017502780
Why is a 5 watt bulb brighter than a 25 watt bulb?
It depends on the type of bulb. Incandescent bulbs convert about 90% of the energy into heat and and only 10% is put off as light. LEDs, for instance, are much more efficient, converting almost 90% of the input energy to light. So, a 5 watt LED will convert about 4.5 watts to light, while a 25 watt incandescent will only convert 2.5 watts into light.
How many amps does it takes to light up a led 100 watt?
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
How many lumens do you need to replace a 400 watt halogen with a led flood light?
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
Which type of light bulbs use ¼ of the energy used by incandescent bulbs?
Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.
How many watts does a 15 inch LED monitor use?
An Energy Star 15" monitor will use around 12 watts operating and around 1 watt or less in sleep mode.
Which light bulb has fewer watts?
LED.
How do the types of light bulbs compare?
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
What is the unit of a light bulb?
The power a light bulb consumes is measured in watts. Light output is often described in terms of watts, as wattage was the only measurement distinguishing different light bulbs in the years before CFL bulbs were commonplace.Light output may also be described in 'candlepower', although this unit of measurement is obsolete and was replaced by the 'candela' in 1948. 'Lumens' are the standard of light measurement in terms of what the human eye can perceive, and you may see these on light bulb packaging occasionally as well.Incandescent light bulbs are generally measured in watts, indicating the power consumed by the bulb.The amount of light of light produced is measured in lumens. Fluorescent bulbs produce more lumens per watt than incandescent. LED lights produce more lumens per watt than florescents.Watts.Watts
