LED bulbs quickly became the most popular choice for homes and businesses thanks to their energy efficiency and versatility—ranging from standard bulbs and LED strips to full-fledged ceiling fixtures.
Before the advent of LEDs, incandescent bulbs had largely been replaced by fluorescent lamps. Despite their higher efficiency, fluorescent lighting had serious drawbacks: a decline in brightness over time and the need for special disposal due to the presence of hazardous materials, such as mercury.
Today, incandescent bulbs are obsolete. Their average lifespan was only about 1,000 hours—a standard established as far back as the 1930s. As for the lifespan of modern LED bulbs, the packaging often bears the inscription “10,000-30,000 hours.”
Nominal service life of LED Bulbs
Manufacturers typically claim that LED bulbs have a lifespan of about 10,000 hours, which is quite a long time. However, in reality, this figure can vary significantly. The key factor is build quality; some bulbs may start to flicker after just a month of use due to overheating, or the bulb may simply stop working. This is due to the quality of the materials used in the bulbs, but it’s only natural—after all, even incandescent bulbs, despite decades of production, could last only a few hundred hours or, conversely, several thousand.
LED lamps in our time
LED bulbs are known for their longevity, but let’s now look at their brightness. Early LED bulbs suffered from the degradation of organic materials, causing their brightness to decline after a few hundred hours of use.
Modern LEDs have improved in this regard. I haven’t come across any bulbs lately where the brightness noticeably decreased after a few hundred hours of operation—or even 1,000. LEDs have become much more reliable and have undoubtedly replaced incandescent and fluorescent bulbs.
