In terms of illumination, heat is a wasteful bi-product, so it's a good job that LEDs produce so little of it. Read this fun LED Monkey blog and discover how Bunnies Prove That LEDs Are Less Wasteful Than Incandescents.

How Much Less Heat Do LEDs Generate?

Given the Heat = Waste formula, it’s easy to work out how little LED bulbs generate compared to other light sources.

Indeed, when you discover that LEDs consume up to 85% less electricity than their more traditional counterparts, it’s not a massive stretch to work out that they produce up to 85% less heat.

But you don’t have to believe us. Indeed, one notable LED lighting manufacturer conducted a test involving a 65-Watt Incandescent Bulb, an equivalently bright 12-Watt LED and two chocolate bunnies!

In the video below, you'll see two identical chocolate bunnies. After being placed into a test chamber, they each endured the heat of a different type of bulb for 90 minutes.

After this time had elapsed, the chocolate bunny under the incandescent bulb has completely melted. This is because the incandescent bulb wastes around 85% of its energy producing heat. Unfortunately for incandescent bulb-users, only 15% remains to create light.

Obviously, with all this energy being expended on heat, the air around the bulb warms up considerably.

A particularly wasteful use of the incandescent’s resources, this is one of the reasons the manufacture and sale of this type of bulb was recently halted.

A Sensible Use of Energy

On the other hand, you’ll notice that the chocolate bunny beneath the LED light bulb barely even breaks a sweat. This is because, unlike incandescents, LEDs expend the vast majority of their energy on the job in hand – producing light.

As such, they waste very little energy heating the air around them.

The constituent parts of an LED light bulb

They achieve this by employing an extremely effective heat sink. This serves to direct the tiny amount of heat they do produce away from their components.

Because of this, LEDs are a lot more efficient than their traditional counterparts and a great deal safer, too!

But this amazing energy-saving feature isn’t the only knock-on effect of LEDs heat-frugality.

Reducing their heat also ensures that they achieve a very long and productive lifespan. In fact, we expect our LED bulbs to last upwards of 50,000 hours. If they’re switched on for 8 hours every day, this translates to around 17.2 years!

This experiment, although quite light-hearted, does serve to illustrate why LEDs are now starting to dominate the domestic lighting market. And, it provides a great reason for you to make the change to LED.
