This light bulb replaces a roughly 13W halogen lamp. Energy-saving LED lamp for caravans, boats, motorhomes, etc. Saves up to 89% energy while maintaining the same light intensity! Specifically designed for mobile applications, these LED light bulbs feature an extended operating voltage range compared to standard bulbs, which can handle charging processes and voltage spikes without compromising the functionality and lifespan of the LEDs. Due to the close placement of the SMDs on the PCB, light points are hardly noticeable. Mercury content (mg): 0, ignition time/start time (s): 0.0, luminous flux retention: 0.7.
