Why do airport downlight installations require a planning horizon of at least 10 years?
High Maintenance Cost
Replacing airport luminaires involves high-altitude work, flight coordination and safety approvals — far more expensive than the fixture itself.
Stable 10-year operation significantly reduces intervention frequency.
Tenders Require Verifiable Data
Owners and designers increasingly demand long-term aging data at the tender stage, not just manufacturer claims.
LM-80 reports have become an important evaluation factor.
Total Cost of Ownership
Initial purchase price is only the tip of the iceberg. Rapid lumen depreciation and higher failure rates drive up decade-long costs.
Low junction temperature plus long-term validation is key to controlling TCO.
LM-80 Core Verification Data for KWCOB
We publicly release LM-80 data for key power ratings, filling the industry gap in high-power long-term validation:
120 W
Tc 85 ℃ · 6,000 h

Report Issued (2017-19)
These tests were conducted in collaboration with BACL Laboratory (USA) and can be directly referenced in tender documents and technical evaluations.
How KWCOB downlight packaging technology supports a lifespan of over 10 years
Low Junction-Temperature Design
Proprietary kilowatt-class COB packaging combined with phase-change heat dissipation effectively controls junction temperature and slows lumen depreciation — the foundation of decade-long stable output.
Optical-Electrical-Thermal Integration
Deep integration of optics, electronics and thermal management minimises interface thermal resistance and enhances long-term reliability.
Platform-Level Validation
The Ø33 mm platform is validated at higher thermal loads, so real operating powers run with greater margin. DIALux simulations closely match field performance.
