Why are led lights hot?

Heat is created in LED lights when the crystal parts of the diode are affected by small deformities. Since not all of the electricity entering the diode is converted into lights, some of it is exhumed as heat. Yes, new technology LED lighting can and will heat up, but compared to lighting in the past, temperatures are much safer. The heat from the lighting will also warm the surrounding environment, but compared to old incandescent lighting, this ambient heat is greatly reduced when using LED lighting.

This reduction in the temperature of the surrounding área is again another example of savings due to the fact that it will now need less energy to cool the area through the surrounding climate control system. KLUS flexible LED strips can be used alone, but we always recommend combining a KLUS aluminum extrusion to get the most out of your money. LED lights have many benefits, but one of the best is that they generate less heat than standard incandescent lights.


emit only 10% of their energy in the form of heat, while incandescent bulbs release around 90%.

The short answer is that LED lights produce heat but don't get too hot to the touch. Understanding how LED lights produce heat isn't that simple, but we'll explain it in detail below. LEDs provide a perfect solution: they work much cooler and most of their energy consumption is used to produce light rather than heat. This means that they need much less energy to deliver the same level of light, even consuming up to 95% less energy (incandescent).

As you can see in the table below, the typical lifespan of incandescent bulbs is much lower compared to LEDs. In my experience, when showing LED lighting fixtures to end users, they always want to touch the lights to see how hot they heat up. Clearly, the slightly higher purchase cost of LED lights is easily outweighed by the impressive lifespan. There's no doubt that LEDs are much more efficient compared to tungsten bulbs, but they also produce some heat.

Imagine what it would be like to create a home gym and discover that you are sweating under the lights even before you start exercising. As I grew older, my interest grew in lighting design and how light impacts everything around us. Typically, LED lights don't heat up enough to burn their environment, but again this depends heavily on the specific space and the product used. So, instead of having the bare light strip or light strip attached directly to a surface such as cabinets, you can have something that helps absorb heat.

This process is what makes incandescent bulbs work (significantly) warmer than LEDs, and if you leave incandescent or halogen lights on for a long time, they can melt due to the heat produced.
