Lifetime - hours (h)

During that lifetime, 80% of the lamps must still be working and emitting 80% of their rated luminous flux.

The lifetime of different types of lighting products, including light bulbs, luminaires, LED lamps, and HID (High-Intensity Discharge) lamps, can vary significantly based on various factors. Here's a general overview of the typical lifetimes for these lighting products:

Incandescent Light Bulbs:

• Incandescent light bulbs have a relatively short lifespan compared to other technologies. They typically last around 1,000 to 2,000 hours.

Compact Fluorescent Lamps (CFLs):

• CFLs are more energy-efficient than incandescent bulbs but have a moderate lifespan. The average lifespan of a CFL is around 8,000 to 10,000 hours.

Light Emitting Diode LED Lamps:

• LED lamps are known for their longevity and energy efficiency. High-quality LED lamps can last anywhere from 25,000 to 50,000 hours or more. Premium LED products might claim lifetimes of up to 100,000 hours.

Luminaires (Light Fixtures):

• The lifespan of luminaires can vary widely based on construction quality and usage. Well-designed and well-constructed luminaires can last for decades, often similar to the lifespan of the light source they house.

High-Intensity Discharge (HID) Lamps:

HID lamps include various types like metal halide, high-pressure sodium, and mercury vapor lamps. Their lifetimes can vary between types:

• Metal Halide Lamps: Typically last around 6,000 to 20,000 hours.
• High-Pressure Sodium Lamps: Generally last around 10,000 to 24,000 hours.
• Mercury Vapor Lamps: Typically last around 10,000 to 24,000 hours.

Fluorescent Tubes (Linear Fluorescent Lamps):

• T8 Fluorescent Tubes: Often last around 10,000 to 24,000 hours.
• T5 Fluorescent Tubes: Generally last around 20,000 to 30,000 hours.
• T12 Fluorescent Tubes: Typically last around 7,000 to 20,000 hours.

It's important to note that the lifetimes mentioned above are approximate averages and can vary based on factors such as operating conditions, usage patterns, and the quality of the specific product. When purchasing lighting products, especially for commercial or critical applications, it's recommended to check the manufacturer's specifications and warranties for accurate information regarding expected lifetimes.
