LED lights are praised for being ecological, less energy-consuming. They have an impressive lifespan, but it seems that the idea that LED lights cause a fire persists in people’s minds. So, Can LED Lights Cause a Fire?

LED Lights: Definition

LEDs are a luminous technology that works using Electroluminescence, a property that certain materials possess that make them emit light when current passes through them.

The mechanism of the LEDs was first discovered in 1907 by British electrical engineer HJ Round who, while experimenting with old glass radii, discovered that silicon carbide crystals emitted light when a certain voltage was applied. No real progress took place with this technology until 1955 when Rubin Braunstein reported that certain diodes emit light in an infrared spectrum when a current passes through them.

The first LED that emitted visible light was created in 1962 and produced red light. As of that moment, the technology began to advance at giant steps, and a unit happened to cost 200 dollars in 1968 to cost 0.5 dollars in the 70s, thanks to the improvements of the manufacturing processes. Today the LED industry has reached gigantic proportions and is expected to reach USD 127.84 billion by 2027.

Why Are LED Lights Better?

Let’s take a look at why LEDs have come to be used suddenly and widely in today’s lighting. We break down the four reasons that explain why there are better options than incandescent bulbs?

  • LEDs Save Energy
  • LEDs Are Safer
  • LEDs Do Not Break Easily
  • LEDs Last Longer

LEDs Saves Energy

We start with the issue of energy saving: LEDs use at least 75% less energy than equivalent incandescent bulbs. A bill of $ 2.74 for the lighting of a Christmas tree during all the holidays with tiny incandescent bulbs comes to be only $ 0.82 if it is compared with similar LED lights. Calculate the cost of a complete set of Christmas lights, and you could save hundreds of dollars over the years.

This saving is also applicable to LEDs that enlighten your home. Acquiring LED lights to replace incandescent bulbs will decrease the amount of light receipt. LEDs are also more efficient than fluorescent lights and are, therefore, a practical option.

LEDs Are Safer

A direct result of the saving in consumption of 75% of LEDs is a decrease in heat emission if we compare them with other light technologies. The larger incandescent bulbs used can reach high temperatures and burn the skin if touched, while the LEDs remain relatively cool to the touch even after long periods of use. This cool feature of LED lights makes it much safer than incandescent bulbs since they can be touched no matter how long they left on.

The most important thing is that since the LEDs are cooler, the danger of fire is less. Although this is relatively rare, the heat produced by larger incandescent bulbs can reach a combustion point and may cause a fire. Decorative LED lights do not get hot enough for this to happen.

LEDs Do Not Break Easily

Incandescent bulbs are composed of fine tungsten filaments through which the current passes, and an evacuated glass ampoule. These two fragile components contribute to the overall fragility of incandescent bulbs, and even a slight impact can break the glass. In contrast, a sudden jolt or strong vibration can break the filament.

On the other hand, LED bulbs are coated with epoxy resin that is stronger than glass, and the same LED assembly is a relatively robust solid-state semiconductor. This composition makes LEDs less prone to breakage, more resistant to shaking of movement and vibration and in general, more durable.

LEDs Last Longer

Even if we don’t consider the durability of their materials, LEDs have a much longer lifespan than incandescent bulbs. The LED lights last 25 times longer. The average lifespan of an incandescent bulb is approximately 1,000 hours. While LEDs can last up to 25,000 hours, at which point their brightness decreases by 70%.

LED lights, in general, are more expensive than incandescent lights and therefore have a higher initial cost. However, this investment is amortized over time by greatly reducing the need to replace the bulbs, as these light up soon and must be replaced, while the LEDs continue to glow.

Can LED Lights Cause a Fire?

Answering the Question: Can LED Lights Cause a Fire?
A less discussed advantage of indoor LED lighting is that the risk of fire can be significantly reduced, by replacing incandescent, fluorescent, halogen or even CFL bulbs with LED lights. Because LED lights consume much less energy and produce much less heat, they are less likely to cause any fire.

The greatest risk of fire caused by ordinary incandescent bulbs, most incandescent bulbs lose 90% of their energy in the form of heat. Therefore, the standard 60 W halogen lamp can produce bright light to fill most rooms, but its temperature is very high. Keeping your hand near the bulb or any light bulb in the accessory is dangerous because it can easily burn your skin and temperature changes can cause the glass of the bulb to break. If the light is not installed correctly and is exposed to any other material, the resulting high heat to lumen ratio can easily cause a fire.

Tip: If you are using an incandescent bulb in your outdoors you should get a separate outlet which will prevent short circuit and fire.
On the other hand, indoor LED lamps consume approximately one-tenth of the electricity at the same light level. All of these indoor and outdoor LED lights generate very little heat, so there is no inherent fire hazard, i.e., there is no risk of burning when the LED is touched.

The interior LED lighting has a unique positioning that is the safest way to illuminate interior spaces, eliminating the risk of damage from lighting; another reason why low-power LED home lighting makes sense.


LEDs are more durable, more efficient, safer and more economical in the long term than any other current light technology. Today they are cheaper and more accessible than ever and represent a shift from established traditional technology to another in a transition of extraordinary speed.

Despite the clear advantages they present, they are not free of potential adverse effects, with the dangers of exposure to blue light being the most important. For this reason, their production is highly regulated by international standards that keep them safe for long-term use.
