LED bulbs are a far more cost-efficient, environmentally-friendly option than traditional incandescent bulbs. With a life expectancy of 20 years or more (25x longer than incandescent), the energy savings from LED bulbs will more than make up for the higher initial purchase price. However, if your LED bulbs burn out quickly, those cost savings are lost.

To understand why people may experience premature LED failure and how to make our LED bulbs last longer, I spoke with Martin Cross, Director at INUI, a UK company specializing in the design, research and manufacture of LED lighting.

According to Cross, there are three critical components of an LED bulb: the LED chip, the LED driver (AC to DC converter) and the heat-sink. When manufacturers skimp on costs for any (or all) of these pieces, it can lead to early failure of the bulb. Cheap LED chips are more susceptible to overheating, which can “greatly shorten the life of the chip." The LED driver must supply a very stable current, or it can cause the LED chip to burn out; Cross says that low cost power supplies may have very few safety features within the electronic circuitry designed to supply stable voltage and current to the LED chip. And if a company uses cheap, thin metal that has poor heat conducting qualities for its heat-sink, it won’t do its job of keeping the chip cool.

So, if you want to make your LED bulbs last longer, here are three steps you can take to get the most out of your investment:

  1. Avoid cheap, no-name LED bulbs. Low cost may indicate that the manufacturer cut corners on components, making the bulb less able to withstand heat or current issues. If you’re not familiar with LED brands, check reviews before you buy.
  2. Don’t use LED bulbs in enclosed fixtures or recessed cans. When LED bulbs are ued in enclosed fixtures and recessed can, excess heat can build up, unless the bulb is specifically rated for that purpose. You can find enclosed fixture rated bulbs on Home Depot or Amazon.
  3. Use dimmable LED bulbs and dimmers designed for LED bulbs. Dimmers that aren’t designed for LED bulbs may not supply the correct current, which can cause flickering, damage the circuitry and shorten the life of your bulbs. Always use a dimmer that is made for LEDs. Similarly, if you are using a LED-compatible dimmer, always use LED bulbs that indicate “dimmable” in the description to avoid circuitry damage.
