LED Billboard Lifespan in Australia: L70 Ratings, Driver IC & PSU Replacement (7–15 Years)

Outdoor LED billboards in Australia are commonly rated at 50,000–100,000 hours (about 7–15 years at 18 hours/day). In practice, the commercial-life trigger is typically driver IC and power supply (PSU) degradation appearing between years 5 and 7, not LED die failure. Key Lifespan Figures Manufacturer L70 ratings (the point where average brightness reaches 70% of as-installed) are the basis for the 50,000–100,000 hour specification. Example operating assumption: 18 hours/day is typical for outdoo
