How long is the service life of a UFO UFO High Bay Light?
The service life of (UFO High Bay Light) is usually based on the rated service life of the LED light source. It is also affected by product quality, use environment, and maintenance methods. It is generally between 50,000 hours and 100,000 hours. It can be analyzed in detail from the following dimensions:
1. Core influencing factors: quality of light source and driver
LED chip life
The light source of the UFO light uses LED chips. The rated life of high-quality chips (such as Samsung, Nichia, Osram and other brands) is generally above 50,000 hours, and some high-end products can reach 80,000-100,000 hours. The "life" here refers to the time when the brightness of the light source decays to 70% of the initial brightness (industry standard LM-80), not completely extinguished.
Poor-quality chips may accelerate light decay due to insufficient heat dissipation design, and the life may be shortened to 20,000-30,000 hours.
Driver power life
The driver is the "heart" of the LED lamp, responsible for stabilizing the current and voltage. Its life usually determines the overall life of the lamp:
High-quality drivers (such as products with isolated design and over-temperature protection function) can last for more than 50,000 hours;
Poor-quality drivers may fail within 10,000-20,000 hours due to capacitor aging and poor heat dissipation.
2. Influence of the use environment
Temperature
Flying saucer lamps are mostly used in industrial places (factories, warehouses). If the ambient temperature is too high (such as over 40℃), it will accelerate the aging of LED chips and driver power. For example:
In high-temperature workshops (such as foundries), the life of lamps may be shortened by 20%-30% compared to normal temperature environments;
Products with efficient heat dissipation design (such as large-area fins and hollow structures) are more adaptable to high-temperature environments.
Humidity and dust
High humidity environments (such as swimming pools and food processing workshops) may cause internal components to become damp. Products with IP65 or higher protection levels must be selected, otherwise the lifespan may be shortened by more than 30%;
If dusty places (such as cement plants and logistics warehouses) are not cleaned for a long time, the heat sink fins will be covered, affecting the heat dissipation efficiency and indirectly shortening the lifespan.
3. Lifespan conversion in actual use
Calculated based on 12 hours of use per day:
50,000 hours ≈ 11.5 years (50,000÷12÷365≈11.5);
80,000 hours ≈ 18.5 years;
100,000 hours ≈ 23 years.
Note: This is a theoretical value under ideal conditions. The actual lifespan needs to be comprehensively judged in combination with the above factors. For example, in a high temperature and high dust environment, even high-quality products may have a lifespan reduced to 7-10 years.
4. Suggestions for extending lifespan
Choose branded products (such as ZC Lighting) to ensure the quality of LED chips and driver power supplies;
Choose the appropriate protection level according to the environment (IP65 and above are suitable for humid/dusty scenes);
Clean the surface of the lamp and the heat sink fins regularly to avoid dust accumulation affecting heat dissipation;
Avoid excessive voltage fluctuations and use with a voltage stabilizer.
In short, the actual service life of a high-quality UFO lamp can usually reach 8-15 years, which is much higher than traditional metal halide lamps (8,000-10,000 hours, about 2-3 years), which is also one of its core advantages in replacing traditional lamps in industrial lighting.
