The most compelling advantage of using PowerLine® LED lamps is a predictable life. LEDs are solid-state devices and, by definition, control current without heated filaments. When used within its design parameters, a PowerLine® LED lamp will operate upwards of 100,000 hours (or 10 years). Furthermore, LED lifetime is not shortened by turning the lamp on and off.
The life of an incandescent bulb is unpredictable - subject to catastrophic failure due to shock, vibration, or cold filament inrush current. Initial powering of a control panel with numerous incandescent bulbs will generally result in several failures.
