What is Rated Life
Rated life, in the context of the lighting industry, is the estimated duration or lifespan of a lighting fixture before its light output significantly diminishes. It is a measure of how long a piece of lighting equipment is expected to last under normal use conditions as defined by the manufacturer. The rated life is an important factor to consider when selecting lighting fixtures as it indicates the reliability and longevity of the product.

For LED luminaires, the rated life is typically measured in hours and represents the duration for which the fixture can reliably produce light. This means that the user can expect the LED luminaire to maintain its light output for the specified rated life period. In the case of traditional light bulbs, such as incandescent or fluorescent bulbs, the Average Rated Life (ARL) is used as a measure. ARL is determined by testing a batch of bulbs and measuring the time it takes for half of them to fail. For example, if a bulb has an ARL of 1,000 hours, it means that in a test of 100 bulbs, 50 of them failed when the test reached 1,000 hours. Most LEDs have a significantly longer ARL, typically around 50,000 hours, with some brands, like Litetronics LEDs, having an ARL of 100,000 hours.
The conditions of normal use, as defined by the manufacturer determine the rated life. ARL tests are typically conducted under conditions that are expected to be encountered in customer applications. However, if a bulb is used in an environment that is unusually hot or cold, exposed to wet or hazardous materials, or located near vibrating machinery or any other “abnormal” situation, it may not reach its ARL. The way an LED light is used also affects its rated life. For example, frequently turning a bulb on and off can reduce its ARL. However, LED bulbs are generally less affected by on/off cycles compared to older types of fixtures like fluorescents, compact fluorescent bulbs, and HID bulbs. In general, a bulb that is turned on and off once a day will have a much longer ARL than one that is cycled multiple times throughout the day.

Perguntas Frequentes
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.
How Long Do LED Ceiling Lights Last
While incandescent bulbs have a lifespan of approximately 1,000 hours, LED ceiling lights are known to last for 50,000 hours or even longer. This extended lifespan can potentially translate into several decades of use at the same rate.
Por Que Minhas Lâmpadas LED Queimam Tão Rápido
As lâmpadas LED têm uma emissão de calor menor em comparação com outras lâmpadas, mas isso também significa que elas podem ser mais suscetíveis ao superaquecimento. Essa sensibilidade ao superaquecimento pode resultar em uma vida útil mais curta para as lâmpadas. Para prolongar a vida útil das suas lâmpadas LED, é importante mantê-las resfriadas. Além disso, certifique-se de que as lâmpadas utilizadas sejam do tamanho adequado para o soquete.
As luzes LED realmente duram 20 anos
As lâmpadas LED são frequentemente anunciadas com uma vida útil de 5, 10, 17 ou até 20 anos. No entanto, é importante notar que esses números às vezes podem ser enganosos. Portanto, sugerimos que nossos clientes façam seus próprios cálculos ou consultem-nos para determinar uma estimativa mais precisa da vida útil das luzes LED.
Qual é a lâmpada de maior durabilidade que você pode comprar
As lâmpadas LED são conhecidas por sua longa vida útil em comparação com as lâmpadas incandescentes. Além de sua longevidade, as lâmpadas LED são eficientes em termos de energia e geram menos calor. Vale notar que as lâmpadas LED são compatíveis com interruptores dimmer, oferecendo flexibilidade nas opções de iluminação.
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.
As luzes LED duram 10 anos
A maioria das lâmpadas LED tem uma vida útil de aproximadamente 50.000 horas, o que indica que você pode não precisar comprar lâmpadas LED de reposição por cerca de 10 anos após a compra inicial. Em contraste, as lâmpadas incandescentes e halógenas geralmente duram apenas de 1.000 a 2.000 horas, enquanto os LEDs dimerizáveis podem durar até 100.000 horas.
