For many, many years, we calculated how bright a light bulb was going to be by checking out their wattage. Nowadays, however, we measure their brightness with something called Lumens. If you’re not already au fait with this new measurement, and are finding it difficult to choose the correct LED bulb take a look at this LED Monkey blog…

So What Are Lumens?

As we’ve already said, most people, when asked about a light bulb’s brightness, will say something like 50 or 100 Watts, not realising that Watts are a measure of power consumption and NOT brightness.

Since the advent of low energy LED Lighting, however, the number of Watts has ceased to be an accurate representation of a bulb’s brightness, because they consume so few of them yet are able to produce just as much light!

For example, a 6-Watt LED light bulb is often capable of producing as much brightness (or as many Lumens) as an incandescent bulb that consumes up to ten times that number of Watts.

This means that not only does this bulb emit the same amount of light as the old-fashioned bulb, it uses 80 - 90% less power to achieve this!

Therefore, using the word “Watts” to describe how bright a bulb is can be both misleading and inaccurate. Lumens are a measure of light, while “Watts” denotes the amount of energy the bulb requires to create it.

Generally Speaking

A simple way to approach this new situation would be to opt for the light bulbs that produce the greatest number of Lumens for the smallest number of Watts consumed.

When you follow this simple rule-of-thumb, you’ll not only be able to purchase exactly the right LED bulbs, you’ll also notice how much your electricity bills fall!

Switching an incandescent bulb for an LED

As we said, replacing your old incandescent light bulbs with energy-efficient LEDs throughout your home will reduce your lighting energy-consumption by up to 90%, so the only way your electricity bills can really go is DOWN!

Easy-to-Follow Rough Guide

Here’s a very rough guide to Wattage/Lumen equivalency:

  • 25W = 230 - 270Lm
  • 40W = 440 - 460Lm
  • 60W = 800 - 850Lm
  • 75W = 1000 -1200Lm
  • 100W = 1500 - 1600Lm
  • 150W = 2500 - 2600Lm
