Most boaters who install LEDs onboard their vessel and find they last for a very short period of time made the mistake of assuming that all LED lights are the same, and so purchased the cheapest LEDs they could that looked as if they would install easily. However, these LEDs were not intended for marine applications, and thus lack the electronics needed to manage voltage levels fed to the LEDs neonskyltar themselves. With LEDs, these electronic regulating systems are known as Drivers, and they perform a host of functions depending upon the application the LED is destined to for. LED drivers can regulate current, allowing an LED light fixture to operate over a wide range of electrical voltages. Some LED marine lights can be simply wired directly into a boat's electrical system regardless of whether that boat as a 12 volt, 24 volt, or even 36 Volt electrical system, because the included drivers automatically sense the current fed to the device and convert it to the proper levels for the LED neonskyltar. These drivers constantly monitor the voltages, and regardless of whether the voltage fed into the device spikes to high levels or drops too low, they maintain the actual voltages fed to the LED at a constant level.
Many LED drivers used in fixtures destined for marine use can also serve to add other functions to the fixture. Drivers can be programmed from the factory to allow the user to connect external dimmer switches, which allows the user to dim or brighten the LEDs much the same as they would an incandescent bulb. These neonskyltar drivers can also be configured to allow external controllers to be connected to the light, allowing operators to cause the light to flash or strobe like a signal light. Although these electronic drivers do add to the cost of an LED marine fixture, they added benefits in features and long LED life do much to offset the added cost.
