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.
Perguntas frequentes
Por que razão as minhas lâmpadas LED fundem tão rapidamente
As lâmpadas LED apresentam uma menor emissão de calor em comparação com outras lâmpadas, mas isto também significa que podem ser mais suscetíveis ao sobreaquecimento. Esta sensibilidade ao sobreaquecimento pode resultar numa vida útil mais curta para as lâmpadas. Para prolongar a vida útil das suas lâmpadas LED, é importante mantê-las frias. Adicionalmente, certifique-se de que as lâmpadas utilizadas possuem o tamanho adequado para o casquilho.
As luzes LED duram mesmo 20 anos
As lâmpadas LED são frequentemente anunciadas como tendo uma vida útil de 5, 10, 17 ou mesmo 20 anos. No entanto, é importante notar que estes números podem por vezes ser enganadores. Por conseguinte, sugerimos que os nossos clientes efetuem os seus próprios cálculos ou nos consultem para determinar uma estimativa mais precisa da vida útil das luzes LED.
As luzes LED duram 10 anos
A maioria das lâmpadas LED tem uma vida útil de aproximadamente 50 000 horas, o que indica que poderá não precisar de comprar lâmpadas LED de substituição durante cerca de 10 anos após a compra inicial. Em contrapartida, as lâmpadas incandescentes e de halogéneo duram tipicamente apenas 1000 a 2000 horas, enquanto os LEDs reguláveis podem durar até 100 000 horas.
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.
O que acontece quando as luzes LED fundem
As lâmpadas LED não se fundem da mesma forma que as lâmpadas convencionais, que deixam de funcionar subitamente quando perdem a alimentação. Em vez disso, as lâmpadas LED deterioram-se gradualmente ao longo do tempo. No decorrer de vários anos, o seu brilho vai diminuindo, um fenómeno conhecido como “depreciação luminosa”. Quando começam a emitir uma luz fraca, é sinal de que chegou o momento de as substituir.
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.
