| Lumens | Incandescent light bulb (watts) | Fluorescent / LED (watts) |
|---|---|---|
| 375 lm | 25 W | 6.23 W |
| 600 lm | 40 W | 10 W |

What is the lumens of LED lights?
In simple terms, Lumens (denoted by lm) are a measure of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear. We have all bought 50W or 60W conventional bulbs or spotlights in the past expecting a certain level of brightness.
1
How many lumens is 3 watts?
A 3-watt LED bulb may produce anywhere between 240 to 320 lumens of illumination. Lumens is a measure of light. 'Lumens per watt' is the measure to identify how much light is produced for the energy or wattage drawn. Accordingly, the minimum efficiency of a 3 Watt LED bulb will be 80 lumens/watt.
2
How many watts does a 100 watt LED use?
The term “60-watt equal” has little to do with any kind of wattage correlation; a 60W equal LED may use as little as 8 watts to operate. It simply means that the bulb, whether CFL or LED, is able to produce as much light as a 60-watt incandescent.

WHAT LED bulb equals 60 watts?
LED Light Bulbs - 60 Watt Equal. With an efficiency up to 80% higher than similar output incandescents, it is certainly safe to say that LED light bulbs like the 60-watt equivalent use less energy than similar incandescent bulbs. You can be sure this is the case thanks to the "60 Watt Equal" in the bulb's name.

How many candle watts are in a lumen?
So, that one candlepower equivalent equals 12.57 lumens. And for you figuring out LED equivalents, first you must know how many lumens your LED's each produce. Then divide that value by 12.57 and you have candlepower of the LED. You don't have foot-candles, remember foot-candles are illuminance.
5
What is a lux compared to a lumen?
Lux is a unit of light measurement where the area is also taken into account. 1 lux equals 1 Lumen/m2, in other words - light intensity in a specific area. Lux is used to measure the amount of light output in a given area - one lux is equal to one lumen per square meter.
6
How many lumens do we get from the sun?
Well, direct outside daylight in the summertime averages somewhere in the neighbourhood of 10,000 foot candles. This is equal to 10,000 lumens per square foot. If you compare this to the output of our thousand watt metal halide bulb earlier, we can see that the sun does a pretty good job.
7
How bright is 1600 lumens?
The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens. Replace a 75W bulb with an LED bulb that gives you about 1100 lumens.

What is the definition of luminous flux?
Luminous flux is the quantity of the energy of the light emitted per second in all directions. The unit of luminous flux is lumen (lm). One lumen is the luminous flux of the uniform point light source that has luminous intensity of 1 candela and is contained in one unit of spatial angle (or 1 steradian).
9
What is the equivalent wattage for LED bulbs?
(The point, after all, is that they draw less energy.) For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts. But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.

What is 400 lumens in Watts?
Lumens and Useful Lumens
| Old Watts | Approx Lumens |

| 40 W | 440 - 460 lamp |
| 50 W | 330 - 400 spotlight 350-450 Useful Lumens (spotlight) |
| 60 W | 800 - 850 lamp |
| 75W | 1000-1100 lamp |

How many watts is 5000 lumens?
For the average living room of 250 square feet, you'll need 5,000 lumens as your primary light source (20 lumens x 250 square feet), equivalent to about five 100 watt incandescent light bulbs, five 23 watt CFLs, or eight 10 watt LED light bulbs.
14
How bright is a lumen?
The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
15
What is a CFL light bulb?
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs.
16
How many lumens is one watt?
An LED bulb can give you as many as 100 lumens per watt as compared to an incandescent bulb that will produce only 12-17 lumens per watt.
