## Convert watts to lumens: We make all the light

The lumen (lm) is the unit measuring the luminous flux. The lumen value indicates the amount of light actually emitted by the bulb. The term lumen comes from Latin and means light.

*“The lumen remains the determining value of the brightness of a light bulb. “*

It’s a safe bet that it will not be very clear if we persist in considering the wattage value of a luminaire at the time of purchase. In these times of modern LED lighting technologies, what really matters is the value in lumens – a concept that describes the brightness of a bulb much better than the good old watt.

**How to convert watts to lumens**

For those who are still struggling to no longer count in watts, it is possible to convert the data expressed in watts into lumens. How to shed light on this point? This is where a simple rule comes into play:

Number of traditional watts x 10 = value in lumens

Lumens indicate brightness more accurately than watts.

To determine the exact lumen (lumen) to replace your old 60 watt incandescent bulb or other bulbs, use this watt-lumen converter.

### Select your bulb model:

15 watts

25 watts

40 watts

60 watts

75 watts

100 watts

Paulmann LED bulbs save at least 80% of the power consumption of a traditional incandescent bulb. They comply with energy efficiency classes A, A + or A ++.

**What is the difference between omnidirectional and reflectors?**

The lumen (lm) is the unit of measurement of luminous flux emanating from a 360 ° illuminating lamp, whether it is omnidirectional (with incandescent bulb) or reflectors.

However, the basics of calculating the brightness of omnidirectional and reflectors are different:

**Omnidirectional lumens**

The lumen (lm) is the unit of measurement of the luminous flux emanating from a lamp illuminating at 360 °.

### The lumens of the reflectors

- All reflectors with a beam angle of 90 ° max. are characterized by a luminous flux of 90 ° and are therefore comparable. The brightness is measured at a 90 ° angle even if the effective radiation angle is smaller.
- All reflectors with a beam angle of up to 120 ° are characterized by a luminous flux of 120 ° and are therefore comparable. These bulbs are not suitable for mood lighting.
- All light bulbs with less than 80% of their total luminous flux in a beam angle of 120 ° fall into the category of “non-directional light” or “free-diffusion light” and are characterized by luminous flux expressed in lumens (lm) which diffuses in the complete perimeter of 360 ° around the bulb.

**Watts are almost meaningless**

The wattage data found today on modern light bulbs are much lower than conventional incandescent light bulbs. For this reason, the technical descriptions on the packaging often only display values between 5 and 10 watts. This is primarily due to the fact that modern lighting technologies consume significantly less energy. This is why the number of watts of modern bulbs does not mean anything more about their brightness.

Think carefully about the use of each of your rooms, the atmosphere you want to create and the amount needed for it.
