What Is the Lifespan of Tp-Link Kasa Light Bulbs?

Tp Link Kasa Light Bulbs

TP-Link Kasa Light Bulbs have an expected lifetime of 25,000 hours based on lab testing. You can expect to run these bulbs for up to 22 years with an average daily usage of 3 hours.

This is approximately five times longer than a CFL and 25 times more than that of an incandescent.

Here is the thing; what makes TP-Link Light Bulbs a smart investment for the long run is their durable construction. You can enjoy long-lasting illumination without the hassle of frequently replacing the bulbs.

Factors Affecting the Lifespan of Kasa Light Bulbs

In reality, the expected lifespan of a TP-Link Kasa Light Bulb would be less than 22 years as some factors may affect its life. Let us walk you through some factors that determine how long your smart light bulb lasts.

1. Usage Frequency

Usage Frequency

Did you know that the more you switch the light on these bulbs, the less they are likely to serve you? Well, the bulbs are actually designed to provide tremendous longevity, though excessive or frequent usage can immensely shorten their life.

This relates to how long they stay on when turned on (for instance, if you leave them on longer during nighttime than during the day). Or, it could be how often you turn your smart bulbs on and off every day.

2. Duration You Leave the Lights On

Duration refers to the number of hours you use your bulb each day could make a great difference. If the bulb is on for longer hours daily without being turned off, it will wear off more quickly as compared to a bulb that gets turned off regularly.

3. Operating Conditions

Installing your light bulb in a suitable environment matters a lot! High humidity or hot conditions without airflow can increase the rate at which the bulb components degrade. Another thing you should know is that very cold temperatures may also impact the bulb's performance in the long haul.

4. Voltage Fluctuations

As a rule of thumb, smart light bulbs typically require a stable power supply in order to function properly. But why exactly is this crucial?

Normally, the stable power connection safeguards the internal electronic components of the bulb. So, if there are power surges and power fluctuations in the voltage, it may pose a risk of premature failure or damage and reduce the lifespan of the bulb.

5. Dimming and Control Methods

Dimming and Control Methods

The TP-Link Kasa Light Bulbs have dimming capabilities and are often controlled by animation methods like voice assistants or phone apps.

These animations usually require additional circuitry, which may generate extra heat and potentially shorten the lifespan of your bulb. If you use the dimming feature more frequently, it is best that you know this feature may shorten the lifespan of your bulb.

7 Ways to Make TP-Link Kasa Light Bulbs Last Longer

Ways to Make TP-Link Kasa Light Bulbs Last Longer

Everybody would like their TP-Link Kasa Smart Bulb to last at least as long as its manufacturer claims it will. If you are curious about how to keep your smart bulb last longer, follow closely as we explain how this is possible.

1. Proper Usage

Since the on-and-off cycles can affect the lifespan of your bulb, you should be mindful of how frequently you use the bulb.

Additionally, re­member to switch off the bulbs when you’re not using them to avoid extended periods of lighting. Consider using smart timers, switches, or other automation features to schedule the bulb. This means that they will power down even if you forget to turn them off.

2. Proper Installation and Maintenance

You should install Kasa light bulbs in areas without extreme temperatures, humidity, or moisture. When installing, be gentle to avoid damaging its internal components.

Additionally, these bulbs require regular maintenance. We recommend that you regularly clean the­ bulbs to remove any dirt or dust that may have settled on their surfaces. The­ buildup of dust can affect heat dissipation and pote­ntially impact the bulb's long-term functionality.

Don’t worry, TP-Link usually issues guidelines on how to install and maintain their smart bulbs. Ensure you follow the guidelines to get the best out of your bulb and potentially increase its lifespan.

3. Cooling and Ventilation

It goes without saying that proper airflow can optimize the bulb’s longevity. Kasa light bulbs generate or produce heat constantly whenever they are in use. If the bulb is in use for longer periods without breaks, it gets hotter, and this might break its elements.

To prevent overheating, it's important to ensure­ that the light bulb has proper ventilation for airflow. The­ best approach is to install the bulb in an area that allows enough space for air circulation.

4. Pay Attention to Power Stability

As we mentioned earlier, the Kasa Light Bulbs require a constant power supply to function properly. So ensure you use a stable power source, voltage stabilizers, or surge protectors to prevent power fluctuations that might damage or shorten the lifespan of the light bulb.

5. Keep Firmware Updated

TP-Link occasionally releases firmware updates to improve the performance of the Kasa light bulb. The firmware may also clear bugs and errors that might have accumulated in the bulb. To extend your bulb’s lifespan, make sure you install these updates whenever they are released.

You can check if your Kasa Light requires a software update by opening the Kasa App, going to “Settings”, and then selecting “Firmware Update.”

6. Choose the Right Brightness Level

Very bright and excessive color temperatures can make the bulb generate more heat, which may reduce its lifespan.

For this reason, try setting the bulb’s brightness level and color temperature to suitable levels. You can even set the bulb to automatically adjust both the temperature and brightness.

7. Check Your WiFi Frequency

Check Your WiFi Frequency

Not so many people know that using the wrong WiFi band or one that isn’t strong enough or fast enough can potentially damage Kasa Light Bulbs over time.

Before setting up a Kasa light bulb, check that your WiFi is stable and compatible with your bulb. Your WiFi could be weak or not strong enough to support the camera, or it could have another band apart from the recommended 2.4 GHz.

Signs It Is Time to Replace Your Kasa Light Bulbs

Of course, TP-Link Kasa Light Bulbs usually have long lifespans, but you should replace them when they have been in use for far too long. Here are some signs that show it is time to change them:

  • Exceeded Lifespan: In case the bulb exceeds the estimated lifespan of 15 – 22 years, it is time to replace it; otherwise, it will start malfunctioning.
  • Unresponsive Malfunctioning: If your bulb becomes unresponsive, especially when connecting to your home system, the bulb might be faulty. You can try troubleshooting the bulb, and if the issue persists, it is best to replace it.
  • Inconsistent Lighting: The bulb experiencing inconsistent lighting or flickering could signify a faulty bulb system. This could be due to the wear and tear caused by continued usage. Replacing the bulb is often the best option in such cases.
  • Color Shift: Kasa Smart Bulbs with color-changing abilities may start experiencing color shifts over the course of their use. If the bulb starts losing its ability to maintain accurate and vibrant colors, it could be time to change the bulb.
  • Dimming Light Output: If your Kasa light bulb is not as bright as it used to be, it could signify that the bulb is reaching its endpoint. The bulbs usually start gradually dimming their light output due to their degrading components.
