What are Lumens in lighting

To purchase a flashlight for personal use, it is mandatory to know What are lumens in lighting first.


Myth: Higher watt in a bulb means brighter light.

Fact: Watt indicates power/energy consumption.


I would like first to clear the most common fact that we get wrong.

We've bought 50W or 60W bulbs in our Easter years. We incorrectly linked the power consumption to the light output. The watt is the unit of the use of energy.

This will change today. Here is when we need to start thinking about lumens. Think lumens as the way to measure how bright we want the light to be. The more, the better. Lumens equal to the brightness.

Quick Fact: If you want more brightness, choose the higher lumens.

Era of Lumen

Old school is always good but in today’s world we always go for something which gives us more.

It is simple; we want more and more lumens mean brighter light. The future is shiny. If you think old is gold, then we still got your back.

The following lumens to watts comparison chart is here to help with that. This chart will work as a ready reference for you like a lumens to watts calculator.

For example, how many lumens in a 60 watt bulb? the answer will be 900 lumens.

Lumens (lm)

Incandescent light bulb watts (W)

Fluorescent / LED watts (W)

375 lm

25 W

6.23 W

600 lm

900 lm

60 W

15 W

1125 lm

Lumens to Watts Comparison Chart


Better than remembering those rocket science formulas. The following image will give a better understanding of how many lumens is bright.

While shopping, there are no guidebooks on how many lumens on needs to consider.

It will depend on the size of the room and its purpose. And also your need for the brightness of the light. Personally, I like a dimmer gaming room. It depends on the position of the light.

The fact that we grow old too comes into consideration. With age, our eyesight becomes weaker for which we will require more light to be able to see clearer. Thus more lumens will be needed.

Let there be light but just enough

Besides, there are still some basic guidelines for all. The following table will help with that.

Using lumens to save energy

We all know now that watt is the power consumption unit. Lumens are the output of light.

In this present world crisis, we need to save energy.

All we need to search for the bulb with the right lumens, and select the lowest wattage. More watts indicate more power consumption.

With new energy efficient LED lights, we no longer need to rely on WATT to buy them.

Choosing the right color for your bulb or flashlight will help in its brightness.

Most of us grew up with the soft yellow emitting incandescent light. Today many colors are available from warmer to the cooler. If you want a dimmer color, you should go for some fancy colors like red or green.

But we all like to head to the light (like in the movies) we advise to go for the white light output. But again the choice of the light color will depend on the rooms you need it for or even for Halloween to Christmas decorations.

Color of the light output

Measurement of Light color

The measurement is done on the Kelvin scale. This is a popular tools for measuring lumen brightness scale. The lower Kelvin is the light will be warmer. Yellowish in color. But as we go high up the scale the color will be cooler. Sort of like the clear blue sky.

Here is to help with the visualization.

kelvin color temperature scale

All electric light sources are that a flashlight or a lamp loses their lumen over time. Same goes for incandescent lights or LEDs.

Technically, the term used to describe this is Lumens depreciation.

We prefer calling it the aging process. Incandescent lights lose about 10%-15%of lumens in their lifespan of 1000 hours. LEDs depreciate more than 20%, but they do have an average life expectancy of 20000 hours.

Lumens life

That’s all the glowing facts friends! Hope you got some idea on what are lumens in lighting now. Do remember about lumens next time when you shop for LEDs or flashlight. And go for less watt level bulbs but with your required lumens. Our earth, our responsibility to protect it.
