This question is ill posed.
Lumen is a unit of measure for how much light comes from the lamp
Watt is a unit of measure for how much energy is used by the lamp
If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb.
I think the relation ship between lumen and watt is something like:
Incandecent bulbs are 15w/lumen
Flourecent bulbs use 40w/lumen
LED bulbs are 70w/lumen
The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter).
Incandescent bulbs have a maximum luminosity of 52 lumens/watt.
Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes)
LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.

What is a lumen?
a measurement of the amount of visible light.AnswerA lumen is the photometric SI unit for luminous flux -i.e. the rate at which an object emits visible light. By 'visible light', we mean electromagnetic energy perceived by the human eye, and the lumen is based on the frequency of green light, to which the human eye is most sensitive.
What SI measurement measures the brightness of a light bulb?
lumen
What LED bulb is equal to 125 incandescent bulb in lumens?
An LED bulb equivalent to a 125 watt incandescent bulb would typically produce around 2000-2200 lumens. It's always best to check the specific product details provided by the manufacturer for the exact lumen output of the LED bulb you are interested in.
What is the function of lumen?
The lumen is the unit of measurement for the total amount of visible light emitted by a light source. It helps to quantify the brightness of a light bulb or luminaire, indicating how much light is produced and reaching a specific area. The higher the lumen value, the brighter the light output.
How many lumens are in a 10w g4 bulb?
It depends on the make !! A cheap one < 100 lumen, a high quality, say Osram 140 lumen
What is the lumen output of a 60W incandescent bulb?
The output of bulbs varies. A typical output of a 60W incandescent bulb is 680 lumens.
What makes a light bulb shine brighter?
Increasing the amount of electrical current flowing through the bulb's filament will make it shine brighter. Additionally, using a higher wattage bulb or a bulb with a higher lumen output will also produce a brighter light.
Does a bulb get brighter the shorter the wire?
The Shorter the wire the brighter the bulb ! Because if it is short then it get brighter and the more batterie the brighter the bulb ! Or the lower voltage the brighter the bulb !
Which bulb is brighter, the incandescent or the LED?
The LED bulb is brighter than the incandescent bulb.
What is the lumen output of a 150W incandescent bulb?
The lumen output of a 150W incandescent bulb is typically around 1600 lumens.
What is the lumen output of a 150W light bulb?
The lumen output of a 150W light bulb is typically around 2600 to 3000 lumens.
What is the lumen output of a 150-watt incandescent bulb?
The lumen output of a 150-watt incandescent bulb is typically around 2,600 lumens.
How many lumen's is a 1003 automotive bulb?
189
What is the lumen output of a 150 watt bulb?
The lumen output of a 150 watt bulb can vary depending on the type of bulb. However, as a general guideline, a 150 watt incandescent bulb typically produces around 2600-2800 lumens.
What is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
What makes a bulb brighter?
more battery's or a better bulb.
