Do Smart Light Bulbs Burn Out? An Important Thing to Know

While regular bulbs burn out over time, you can use smart light bulbs for years without encountering any issues with them. It can make you think about the lifespan of smart light bulbs or whether they burn out like regular bulbs or not.

The most accurate answer to this question is Yes, smart light bulbs burn out but not like regular bulbs. While Incandescent light bulb burns out and gets unusable completely, smart light bulbs do not really burn out instead they get faded over use.

In this article, we will explain how smart light bulbs burn out, their total lifespan, factors that affect their lifespan, and much more. So, without any further ado, let’s get started.

Are Smart Light Bulbs Burn Out? 

Let’s start with the question of whether smart light bulbs burn out or not.

The phrase “Burn Out” is commonly used to describe a light bulb that is no longer able to function. However, it is not an accurate term when referring to smart bulbs.

It’s because smart bulbs do not burn out suddenly like traditional bulbs. Instead, they gradually lose their brightness, or lumens, until they can no longer effectively provide the desired lighting output.

However, the lifespan of a smart light bulb may be lower than ordinary LED bulb but still, it is efficient to use it for your smart home. Let’s learn about the lifespan of a smart bulb in more detail below.

For How Long Does a Smart Light Bulb Last?

The lifespan of a smart light bulb is about 25,000 hours. Though some brands advertise that their smart light can last up to 25 years, it is simply misleading as how many years it will run until it burns out completely depends on the number of hours it was being used.

You can calculate the lifespan of your smart light bulb using a simple formula. Here it is –

Actual lifespan in year = (life expectancy in year x estimated hours in daily use) ÷ actual hours of daily use.

For example, if the lifespan for your smart light is 25 years, the estimated use is 8 hours daily and the actual is 9 hours daily, then the actual lifespan for your light will be around 22 years.

However, the lifespan of a smart light may vary for different brands. Here is the estimated lifespan for different brands:

Smart Lighting BrandExpected Lifespan (hours)
Philips Hue25,000
Nanoleaf Essentials25,000
IKEA Tradfri25,000
TP-Link Kasa25,000
Eufy LumosLess than 20,000
Hive Active25,000
Xiaomi Mi Yeelight25,000

Here, you can see from the table above that the average lifespan for smart light bulbs is 25000 hours. After this, the lights will fade and dim which refers to the term “Burn Out”.

Factors That Make Smart Bulbs Burn Out Quickly

As now you know smart light bulbs burn out after a certain time, let’s learn the factors that reduce the lifespan of the smart bulb and make them burn out quickly.

  1. High Temperature.
  2. High Number of Usage Hours.
  3. High Voltage.

While it is obvious that the number of usage hours reduces the lifespan of a smart bulb, the high voltage can create high temperature and a high temperature is the main factor to make the smart bulb burn out quickly.

So, do not use the smart light when it isn’t necessary, or use the motion sensor feature of the light to make it last longer. You can also ensure accurate voltage and proper air ventilation in the room to avoid temperature and increase the lifespan of the smart light bulb.

Frequently Asked Questions and Answers (FAQs)

Why Has My Smart Bulb Stopped Working?

To conclude, every electronic device has an end so with the smart light bulb. Although they do not burn out like regular bulbs, they lose their lumens over time, and in the end, they become too dim to meet your requirement. It is called “Lumen depreciation” which results in the individual diodes in the LEDs losing function one by one. We hope, now you have no confusion regarding this topic after reading this article.
