Clear answer
Clear answer, explained.
Instead of failing suddenly, LEDs gradually decline in brightness over time, usually rated to L70 (70% of original light output) . The actual lifespan depends on factors such as operating hours, ambient temperature, fixture quality, and environmental conditions (e.g. dust, vibration, humidity). In 24/7 industrial environments, fixtures still provide many years of reliable performance with significantly less maintenance than traditional lighting systems.
Key points
What this means in practice.
- Typical lifespan: 50,000–100,000+ hours
- Equivalent to 5–15+ years depending on usage
- Gradual light reduction (L70), not sudden failure
- Longer lifespan than metal halide or fluorescent systems
- Reduced maintenance and replacement frequency
- Performance influenced by environment and installation quality
When this applies
Best-fit environments.
- Warehouses and distribution centres
- Manufacturing and industrial facilities
- High-bay and ultra-high-bay environments
- Facilities operating extended or 24/7 hours
