A lumen is a measure of how much total light a bulb produces. Incandescent (1156) bulbs spray their light through almost 360 degrees and lamp housings designed for them rely on that. Most LED lamps put all their light out in a narrow cone and work poorly with standard 1156 housings. However, there are LED assemblies that have their light-producing chips arranged around a sphere and they work well in standard housings.
The LEDs you see on commercial vehicles are mounted in housings designed for their narrow cone output, that's why they look bright.
A standard 1156 bulb puts out about 400 lumens when new. As of January 2010, I haven't found an LED replacement that puts out any more, and most are only 50 lumens or so, not enough for a standard 1156 housing.
To confirm the above: From Bosch Automotive Handbook7th ed. a 1156 (BA15S) Stop/Turn 21W bulb puts out 460 lumens. For a 5W Side marker / Tail BA15S it is 50 lumens (strangely low, I know) and 10W Tail light 125 lumens.
If replacing with a warm white LED, then that is how many lumens you need to match the brightness (as well as light direction being good). BUT, if using a Red LED for a brake light or an Amber LED for Turn signals, then less lumens are needed. This is because the Red lens of a brake light filters out all the blue, yellow, green, etc out of white light, but filters nothing from a Red LED. The question now is: What is the percentage of "Red" in the light output of a "White" incandescent bulb?

A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
How do you know which LED bulb will replace a common Bulb?
Check the lumens of the common bulb and match it with the equivalent lumens of the LED bulb. Also, consider the color temperature and base type of the common bulb to find a suitable LED replacement. Make sure to check the size and shape of the LED bulb to ensure it fits in the fixture.
How many lumens in a g9 bulb?
A typical G9 bulb has a brightness ranging from 200 to 400 lumens, depending on the specific model and wattage of the bulb.
How many lumens in a 1141 bulb?
A 1141 bulb typically produces around 185 lumens.
How many watts is a 1141 auto bulb?
A 1141 auto bulb typically consumes around 18-21 watts of power.
How many lumens for an led replacement vs stock 1157 bulb?
A 150 lumen red LED will be as bright if the tail light lens is red. A 220 red led will be brighter than a regular 1157. The colored lens will make a white led bulb not as brighter due the filtering affect it has on the light wave lengths. A white LED replacement would have to be 400 lumens to equal the 1157's brightness.
How many lumens are in a 1000 watt incondescent light bulb?
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.

How many lumens are produced by a 150 watt bulb?
A 150 watt bulb typically produces around 2600 to 2800 lumens.
What is the maximum number of lumens produced by a 150 watt light bulb?
The maximum number of lumens produced by a 150 watt light bulb is typically around 2600 to 3000 lumens.
How bright is an led bulb marked 100 lumen?
Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts. The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.
Is a 35 lumens bulb as bright as a 60 watts bulb?
Well friend, lumens and watts measure different things. Lumens tell us how bright a bulb is, while watts tell us how much energy it uses. A 35 lumens bulb may not be as bright as a 60 watts bulb, but it can still light up a room beautifully in its own gentle way. Just remember, every light has its own special glow that can bring warmth and comfort to any space.
