What is Long Life
“Long Life” in the lighting industry refers to the extended lifespan of LED light fixtures compared to traditional incandescent bulbs. LED light fixtures have been tested to last as long as 100,000 hours, which is significantly longer than the approximately 1,000 hours of lifespan for incandescent bulbs. On average, LED light bulbs can last for at least 20 years without needing to be changed.
The extended lifespan of LED light fixtures brings several advantages. Firstly, it reduces the need for frequent bulb replacements, saving both time and money. With LED lights lasting for such a long time, maintenance workers can focus on other tasks instead of constantly changing bulbs. Additionally, the longevity of LED fixtures makes them a cost-effective investment.

There are factors that can affect the actual lifespan of LED fixtures:
Heat is one of the greatest enemies of LED bulbs. Unlike incandescent bulbs, which become stronger as they heat up, LED bulbs are susceptible to heat. If the heat is not properly dissipated through a well-designed heatsink, the LED circuits can be damaged, leading to a shorter lifespan. In some cases, LED bulbs can die in as little as one year if the heatsink is not effective. Some commercial and industrial LED bulbs incorporate small fans, similar to computer fans, to draw cool air through the lamp and prevent overheating.

The environment in which the LED bulb is placed can also affect its lifespan. If the bulb is exposed to a hot and humid environment or is installed in an enclosed area, heat can build up and reduce its life expectancy. To address this, special LED lights are designed for use in inhospitable environments, and vapor tight fixtures are recommended. It is worth noting that most LED bulbs purchased from reputable manufacturers have been tested and approved for use in enclosed environments, minimizing any negative impact on their lifespan.
Another factor that used to affect the lifespan of LED bulbs is the capacitor. However, substantial improvements have been made in capacitor technology over the past decade. Most LED bulbs now last at least as long as the estimated lifespan printed on the LED box. As LED bulbs age, they do not usually fail suddenly but instead gradually produce less light. Manufacturers have determined that the point at which the dimming becomes noticeable is at around 70% of the original lumens. This is why many LED bulbs receive an L70 rating, indicating that after a certain number of hours of use (e.g., 25,000 hours), the bulb will only be producing 70% of its original light.
常見問題
為什麼我的 LED 燈泡燒得這麼快
與其他燈泡相比，LED 燈泡的發熱量較低，但這亦意味著它們更容易受到過熱影響。對過熱敏感可能會導致燈泡的使用壽命縮短。為延長 LED 燈泡的壽命，保持其冷卻至關重要。此外，請確保所使用的燈泡尺寸與燈具完美配合。
LED 燈真的可以使用 20 年嗎
LED 燈泡在宣傳中往往標榜具有 5 年、10 年、17 年甚至 20 年的使用壽命。然而，需要注意的是，這些數字有時可能會產生誤導。因此，我們建議客戶自行計算，或向我們諮詢，以確定更準確的 LED 燈使用壽命估算。
Do LED Lights Last 10 Years
Most LED bulbs have a lifespan of approximately 50,000 hours, indicating that you might not need to purchase replacement LED bulbs for around 10 years after your initial purchase. In contrast, incandescent and halogen bulbs typically last for only 1000 – 2000 hours, while dimmable LEDs can last for up to 100,000 hours.
How Long Do Cheap LED Lights Last
As previously stated, when used correctly, cheap LED lights can last for approximately 30,000 to 50,000 hours, which is significantly longer than the average lifespan of an incandescent light bulb, which is only around 1,000 hours.
What Happens When LED Lights Burn Out
LED bulbs do not burn out in the same way as regular bulbs, where they suddenly stop working when they lose power. Instead, LED bulbs gradually deteriorate over time. Over the course of several years, their brightness diminishes, a phenomenon referred to as “luminous decay.” When they start emitting a faint light, it indicates that it is time to replace them.
Can You Overuse LED Lights
It is important to note that LED light therapy has an excellent safety record. In fact, there is no risk of overusing LED lights. Overuse will not result in any harm or damage to the skin. However, it is worth mentioning that overusing LED lights will not expedite the desired results either. For optimal outcomes, it is recommended to use LED light therapy at least three to five times a week for a duration of four to five weeks.
