The durability of halogen bulbs leaves a lot to be desired. Because they are at the basic level a simple incandescent bulb, they too have a thin wire filament and fragile glass bulb used in their construction. 

This means that the bulb is sensitive to rough handling, and a halogen bulb exposed to frequent vibration can experience premature failure due to the wire filament becoming fatigued and breaking.

Filament breakage is more common when the lamp us exposed to vibration while in operation due to the heated filament being less resilient and more easily separated from its anchor contacts. 

Additionally, halogen bulbs are extremely sensitive to wetness, which can present a serious problem for lamps installed on boats. 

Should a fixture housing seal fail, or water somehow otherwise enter into the lamp and contact the bulb, the bulb will normally simply heat up and then quickly fail.

Halogen boat lights have remained popular primarily due to their cheapness. 

Like their basic incandescent brethren, the halogen bulb is very simple in design and cheap to manufacture, and so it costs less at purchase. 

So, despite its relatively short lifespan, poor durability, and high heat, the halogen has remained a favorite because it can produce a lot of light for little initial money.

LED Boat Lights-

LED boat lights although not perfect have at this time pretty well solved the majority of issues associated with standard incandescent boat lighting. 

Costing more than halogen lamps, the initial cost of LEDs continues to drive some potential buyers away, but a look at the benefits reveals how this initial cost is in reality deceptive, and how LEDs can actually be more cost effective in the long run.

LEDs are a solid state form of lighting that does not rely on a wire filament or glass bulb to produce light. 

Rather than heating a filament to cause ljusskyltar it to glow and emit light, and LED passes current through a piece of sem-conducting material, which in turn causes the material to radiate photons, or as they are more commonly known, visible light.

This process does produce some heat, but very little, and since it is so efficient little energy is wasted as heat and is instead radiated as light energy. 

In other words, and LED fixture will not present a burn or fire hazard due to its operating heat, making it an ideal candidate for installation into cabins as overhead lighting.

LED lighting is known primarily for two things, one of which is their extremely long operating life. A typical LED light in the 40 watt range will have a rated operating life of about 50,000-60,000 hours. 

Like incandescent lamps, as power goes up, the rated life of LEDs tends to drop, however, this drop is not as drastic with other forms of lighting, and LED fixtures up to 300 watts still tend to have lifespans approaching 50,000 hours or more. 

This long life means an LED will last several years before it requires replacing, doing much to help offset its higher initial costs.
