What is Rated Lamp Life
Rated lamp life refers to the estimated operational lifespan of a specific type of lamp or light source. It is a reliability property that indicates how long a lamp is expected to function before it fails or depreciates in performance. The Rated Lamp Life is typically expressed in hours and is determined by the manufacturer. The rated lamp life is commonly a statistically-determined estimate of the median operational life of the lamp. This means that it is based on data and analysis of a large sample of lamps to determine the average lifespan. The specific conditions under which the lamps are tested and the failure criteria used can vary depending on the type of lamp.
Please note that the rated lamp life is different from the Lumen-maintenance life. The Lumen-maintenance life measures the elapsed operating time at which a specified percentage of lumen depreciation or maintenance is reached. In contrast, the rated lamp life focuses on the overall operational lifespan of the lamp. Factors such as heat, vibrations, and cycling patterns can affect the rated lamp life of different types of lamps. For example, LED lamps have proven to be more durable in environments with vibrations compared to incandescent, fluorescent, and HID lamps. Additionally, cycling the lamp on and off can have a negative impact on the overall lamp life of fluorescent sources, while LED and incandescent lighting are not significantly affected by cycling.

常見問題
What Style of Lamp Gives the Most Light
If you are looking for a floor lamp that can provide ample lighting to your entire room, then you should opt for a lamp with LED bulbs. These bulbs emit the highest number of lumens per watt, making them the brightest option available.
What Are the 4 Categories of Lighting
There are four primary categories of lighting – ambient, task, accent, and decorative.
Why LED Is Better Than Bulb
Not only are LED holiday lights more energy-efficient, but they also offer several advantages over traditional bulbs. One major advantage is their safety feature – LEDs emit less heat, reducing the risk of fire or burns. Additionally, LEDs are more durable as they are constructed with epoxy lenses instead of fragile glass, making them less prone to breakage.
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。
Why Do LED Bulbs Not Last Long
Unlike traditional incandescent light bulbs, LED bulbs do not generate light through heat. This characteristic contributes to their high energy efficiency. However, one drawback is that LED bulbs can be susceptible to overheating, which may lead to premature burnout.
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 Much Does It Cost to Leave LEDs on for a Year
CFL: Leaving 10 CFLs on for one hour per day when they’re not needed will result in an additional $6 added to your annual lighting expenses. On the other hand, if you leave 10 LEDs on for one hour per day when they’re not needed, it will only add an extra $5 to your lighting bills each year.
調光器會縮短 LED 燈泡的壽命嗎
使用調光器來調節 LED 燈泡的亮度，實際上可以延長其使用壽命。通常情況下，不具備調光功能的 LED 燈泡可使用約 40,000 小時。然而，透過使用調光開關調暗光線，您可以有效提高其平均額定壽命（ARL）。
What Does T8 Mean in Lighting
The term “T8” in lighting refers to the designation used in fluorescent lamp nomenclature. The letter “T” signifies that the lamp has a tubular shape. The number following the “T” indicates the diameter of the lamp in eighths of an inch.
