Clear answer
Clear answer, explained.
Instead of failing suddenly, LEDs gradually lose brightness over time, typically reaching end-of-life at L70 (70% of original brightness) . The actual lifespan depends on factors such as operating hours, ambient temperature, fixture quality, and driver performance. In commercial environments with long operating hours, LEDs can still provide many years of reliable service with minimal maintenance.
Key points
What this means in practice.
- Typical lifespan: 50,000–100,000 hours
- Equivalent to 5–15 years in commercial settings
- Gradual light reduction rather than sudden failure
- Longer lifespan than fluorescent or metal halide lighting
- Reduced maintenance and replacement costs
- Performance depends on environment and product quality
When this applies
Best-fit environments.
- Offices, retail spaces, and warehouses
- Industrial and commercial facilities with long operating hours
- Buildings replacing fluorescent or
- HID lighting
