Why Is My Led Light Bulb Smoking? (Reasons and Solutions)

Since LED light bulbs are long-lasting and energy-efficient, people nowadays choose them for their homes, workplaces, gardens, playgrounds, or anything that requires light. In addition, LED light bulbs have come a long way from the early stage, and there are different types of bulbs in the market now. But the thing is that you can face various issues with LED light bulbs like other bulbs as well. Anytime you find smoke coming from your LED light Bulb and think it is a fire hazard. 

So, knowing why your LED light bulb is smoking is essential. Most of the time, this occurs due to the need for a more professional installation of your bulb. If the LED light bulb is cheap and of low quality, you can often see smoke coming from your light.

On the contrary, sometimes, when the LED light bulb has not had enough large heat sinks, then the problem can arise. In this article, I will briefly explore some possible reasons for smoking LED light bulbs smoking. 

Why Is My Led Light Bulb Smoking

What Are the Reasons Why My Led Lightbulb Smoking?

Though LED lights are generally very reliable, they can start to smoke if you can’t use them correctly. Since there can be various reasons behind the issue, you must first find out the exact one.

Reason 1: Because of the Improper Cooling System

In most cases, your LED bulb light can smoke if it can’t be cooled properly. So, the actual thing that happens behind the improper cooling procedure is the need for proper air circulation or the lack of enough large heat sinks. 

However, you must remember one question: Is your LED light bulb smoking a replacement for different kinds of the bulb like a 50W halogen downlight?

When Led light manufacturers cut corners, they may use lower-quality materials that can break down easily and even start to smoke when used. That’s why it is common to find the electrolytic capacitors across the rectifier circuit underrated after opening the smoking LED light bulb. 

However, poor-quality LED light bulbs manufactured for export could be better. Again, before being branded for the target market’s voltage, the producers made the lights using budget manufacturing processes. So, you must purchase high-quality LED light bulbs from a reputed brand.   

Reason 5. Because of Improper Installation

Improper installation is another reason get an LED light bulb smoking. If you can’t screw your LED light bulb in tight enough, it can start to smoke. On the contrary, when the LED light bulb comes into contact with any flammable materials, the light can start to smoke too. So, while your LEDs are generally reliable and safe, you should use the light properly to avoid any potential issues.

Frequently Asked Questions

Why Do LED Light Bulbs Get Hot?

LED light bulbs get hot, and it is very natural. It would help if you didn’t worry about the thing because LED light bulbs get hot due to the internal components that create the light. However, the base of your LED light bulb acts as a heat sink, allowing your bulb’s surface to maintain a perfect temperature. But here, if the components cannot adequately ventilate, they can produce more temperature output. 

How Long Should My LED Light Bulb Last?

The average lifespan of your LED is often rated up to 50,000 hours. However, this is about 50 times longer than a conventional incandescent and even 30 to 25 times longer than a traditional halogen. On the contrary, LED light bulbs are 8 to 10 times longer than a typical CFL. Again, if you use an LED light bulb 12 hours a day, it is rated t 50,000 hours, which means it will last more than 11 years. 

Is a Burnt LED Light Bulb Toxic?

In general, red LED light bulbs contain eight times the lead found in a yellow LED. But when the lead gets converted to smoke, it turns into a neurotoxin and exhibits significant noncancer and cancer-causing properties because of the high content of arsenic and lead. So, a burnt LED light bulb is toxic. 


It is important to figure out the reason for getting your LED light bulb smoking because the issue can get out of control, and you may have a serious fire hazard.
