Dimming after years usually means thermal and driver aging. This maintenance list slows it effectively.
Parking lighting: prioritize uniformity and safety; fixtures need wide temperature tolerance and IP54+; radar/microwave sensors cut energy sharply.
Thermal design drives lumen depreciation: die-cast fins plus thermal compound is proven; keep junction temperature below ~85C, backed by LM-80 reports.
Whole-unit efficacy (lm/W) is the core of energy saving: higher efficacy at the same lux means lower wattage and clearly lower bills.
