Do you wish to have a bright room especially in locations of your house that don’t have natural light? Unfortunately, some lighting options generate heat that can cause problems. Is that the case with LED Lights? Do LED lights produce heat? Let’s address this issue. 

Do LED Lights Produce Heat?

Yes, LED lights produce heat. However, this heat is only a fraction of what incandescent or halogen bulbs produce. LED lights are also more efficient using that energy. The heat at which a LED light will operate depends on the temperature of the room and the fixture you place it in. 

LED bulbs are also cool to the touch since they don’t generate infrared radiation heat. IR radiation heats incandescent lamp surroundings, making them too hot to touch. However, the absence of infrared radiation allows LED light bulbs to be installed in areas where conventional lighting sources can heat and affect delicate products like textiles or food.

Do LED Bulbs Get Hot To The Touch?

Some LED companies claim that LED bulbs do not produce heat. However, that’s not true because any device that uses electricity generates heat, including different types of bulbs. 

Moreover, the temperature at which the casing of the LED functions is determined by room temperature and the fixture. That’s why some LED lamps in your home may appear warmer than others. 

LED lamps also contain substances that convert the high voltage electricity to lower voltage which’s perfect for the LED chips. Because of this, LED light bulbs are very sensitive to heat than other types of lamps. 

What About Bulbs That Carry Warnings?

Some cheaper lamps have instructions that warn you not to use them in an enclosed fixture. If you ignore the warnings and use them, heat can build-up and reduce the lifespan of the lamp’s components. 

This means you should pick a bulb designed for full enclosures if you desire to use fully enclosed fixtures. Generally, LED lights are an ideal option for locations where heat can cause problems because they generate lower heat. 

For example, imagine building your home gym and sweating under the lights even before you begin exercising. That’s why LED bulbs are a better choice since you can illuminate your gym fully without making it hotter than it needs to be.

Incandescent Bulbs vs. LED

It’s important to have some basic understanding of how these two types of bulbs operate. LED bulbs have different elements compared to traditional lamps. They also have diodes that change current into light. 

On the other hand, incandescent lamps generate light by warming up the wire filament . These lamps seem affordable because they are cheap to manufacture, but their shorter lifespans mean you’ll have to replace them more often. 

On the other hand, incandescent bulbs adapt to different currents and outputs since they are available in different voltages. Unfortunately, these incandescent bulbs aren’t as energy-efficient because 90% of the energy consumed is used to produce heat. This comes with a risk of causing fires.

What Are Other Disadvantages of Incandescent Lighting?

Apart from consuming a lot of energy, incandescent bulbs also have shorter operating hours. Since the average lamp lasts 1,200 hours, you will need several bulbs to equal the operating hours of one LED bulb

Clearly, the higher cost of LED bulbs outweighs the shorter lifespan of incandescent lamps. Bear in mind that LED lamps generate less heat and also have greater efficiency than conventional incandescent lighting sources

Which Bulbs Generate the Least and Most Heat?

If you are not yet convinced that LED lighting is the perfect choice for your home, let’s see which lamps generate the least and the highest amount of heat.

  • LED lamps: 20-50%
  • Fluorescent tubes: 20%
  • Fluorescent lamps: 40%
  • Halogen lamps: 80%
  • Incandescent lamps: 85%

As you can see, LED bulbs generate the least heat, making them more efficient than incandescent or halogen light lamps. However, this differs depending on the type of lighting and its energy rating. Although fluorescent lamps do not generate a high amount of heat, most people don’t like them. 

They tend to get cold and cause the flickering effect, which can cause headaches or migraines. Halogens also generate light at 360 degrees, which means they waste energy since they point much light up towards the ceiling. 

What’s the Average Lifespan of Different Bulbs?

Heat can cause your bulbs to wear. For instance, incandescent lighting has a filament that produces light after heating up. Unfortunately, cooling and heating can damage your bulb and impact its lifespan. 

That’s why we want to analyze the amount of heat that’s produced by different types of lamps.

From the above information, the average lifespan of incandescent lamps is lower than LEDs. The reason why LED lighting lasts longer is that it is exposed to low temperatures. On the other hand, the frequent heat of conventional incandescent lamps comprises its lifespan.

What Is the Light Output of Different Lamps?

If a lamp generates less heat, does it mean it generates less light? No. This causes confusion most of the time because lamps have different wattages. You may be wondering how a small wattage bulb can generate the same amount of light as that of a higher wattage incandescent lighting.

Person trying to find out if LED lights produce heat

Incandescent lamps feature a filament that requires more power to heat up so that it generates light. However, LED bulbs have diodes that produce light. This means you can select a lower wattage bulb and still get the same brightness.

For instance, you will need an LED lamp that’s 8-10 watts if you are using a 60 watts incandescent bulb to get the same amount of light.

Which Light Bulbs Produce the Least Heat?

LED bulbs produce less heat compared to incandescent lamps. This means they keep living spaces cool using less energy. 

Do LED Strip Lights Produce Heat?

Yes, LED strip bulbs produce some heat like other lights. However, they don’t get hot to the touch. So you can touch them and not get burnt.


While LED bulbs generate some heat, they are cooler than traditional incandescent lamps. This makes them a greater option for illuminating sensitive objects like artwork that can be damaged by heat.
