Bulb Lifespan & Replacement Maintenance
LED (25,000+ Hours)
Operating 5 hours daily, a quality LED bulb lasts over 13 to 15 years before dimming to 70% lumen maintenance (L70).
CFL (8,000 Hours)
Lasts approximately 4 years, but degrades with frequent on/off switching cycles and contains hazardous mercury vapor requiring specialized recycling.
Incandescent (1,000 Hours)
Burns out in just 6 to 7 months of normal household use, requiring 25 bulb replacements over the lifespan of a single LED.
