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 SI measurement measures the brightness of a light bulb?
lumen
Which bulb is brighter 168 or 194?
168
How many lumen in a 2.3w led bulb?
The brightness of an LED bulb is usually measured in lumens. However, the number of lumens produced by a 2.3W LED bulb will vary depending on the specific type and model of the bulb. It is best to check the manufacturer's specifications or packaging for the lumen output of the specific bulb you are referring to.
Is 650 lumen's bright?
A 50 watt incandescent bulb is about 650 lumens.
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.
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 !
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.
How many lumen's is a 1003 automotive bulb?
189
What makes a bulb brighter?
more battery's or a better bulb.
If you have brighter bulbs will the battery last longer or will it run down quickly?
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
What happens to a bulb when you move it closer to a battery on a circuit?
The bulb will get brighter
What SI measurement measures the brightness of a light bulb?
lumen
What kind of battery makes a bulb shine brighter?
Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.
What effect did the light bulb have?
A brighter future!
How do you make a bulb brighter?
change the battery
