Understanding RV Lighting 

Before you consider upgrading your RV lighting, it is essential to understand the numerous types of lighting options available. 

Incandescent Lighting 

Incandescent lighting is the traditional type of light bulb used in RVs for many years. They produce light by heating the filament present inside the bulb. Although they are relatively inexpensive and easy to find, they are not as energy efficient as other types of lighting. Also, they have a shorter lifespan as compared to other lighting options. This means that you will have to replace them more frequently, and they will consume more power. 

Fluorescent Lighting 

Fluorescent lighting is another option that has been used in RVs. These lights work by passing an electric current through a gas, which in turn produces ultraviolet light. This ultraviolet light then stimulates a phosphor coating on the inside of the bulb, producing visible light. Fluorescent lights are more energy-efficient than incandescent lights and have a longer lifespan, but they can be more expensive and may contain harmful chemicals. 

LED Lighting 

LED lighting has become increasingly popular in recent years due to its energy efficiency, long lifespan, and ability to produce bright light. LED stands for light-emitting diode, and they work by passing an electric current through a semiconductor material. This causes the material to emit light. LED lights are highly efficient and can last for up to 50,000 hours. They are also durable and resistant to vibration and shock, which makes them a good choice for RVs.

Voltage Requirements for Each Light

The typical voltage for incandescent lighting in RVs is 12 volts DC (direct current). This is because RVs typically have a 12-volt electrical system. This system is powered by a combination of the RV’s battery and a converter that converts AC (alternating current) power from a shoreline or generator to DC power. Using a 12-volt incandescent light bulb in an RV’s electrical system is a good match. This is because it can be powered by the RV’s battery and doesn’t require additional voltage conversion. 

Correspondingly, fluorescent lights typically use a higher voltage than incandescent lights, usually around 110-120 volts AC. This is because fluorescent lights require a special electronic ballast to regulate the current and start the lamp. Since RVs have a 12-volt electrical system, a separate power converter or inverter is needed. Consequently, it converts the 12-volt DC power to the 110-120 volts of AC power needed to run the fluorescent lights. 

Lastly, LED lights typically operate on 12 to 24 volts DC, which makes them a suitable match for the RV’s electrical system. They don’t require a ballast and are highly energy-efficient, so they draw less power from the RV’s battery. LEDs can be wired directly to the RV’s electrical system and don’t require additional voltage conversion like fluorescent lights. 

However, the voltage rating of LED lights should be checked before purchasing to ensure it is compatible with the RV’s electrical system. In short, the different voltages used for each type of light are mainly because of the way they are constructed, the technology they use, and their compatibility with the RV’s electrical system.

Pros and Cons of Using 120-Volt Fixtures in RVs 

Here are some benefits and drawbacks of using 120-volt fixtures in RVs.

Benefits 

Increased Brightness

One of the main benefits of using 120-volt fixtures in RVs is increased brightness. 120-volt fixtures are typically more powerful than 12-volt fixtures and can produce significantly more light. This can make a big difference in the overall feel of the RV, especially in darker areas like the bathroom or the bedroom. 

Improved Energy Efficiency

Another benefit of 120-volt fixtures is that they are more energy-efficient than traditional 12-volt fixtures. This means they will use less power from the RV’s battery and can help extend the battery life. 

Added Versatility

120-volt fixtures are also more versatile than 12-volt fixtures. They come in a wider variety of styles and designs, making it easier to find one that matches your RV’s interior.

Drawbacks 

Safety Risk

A major drawback of using 120-volt fixtures in RVs is the potential safety risk. 120-volt fixtures use a higher voltage than traditional 12-volt fixtures. As a result, they can be more dangerous if they are not installed or wired correctly. 

Requires An Additional Power Source

Another drawback is that 120-volt fixtures require a separate power converter or inverter. It is mandatory as it converts the 12-volt DC power to the 120-volt AC power needed to run the fixture. Ultimately, it can add extra cost and complexity to the installation process. 

Lower Compatibility

Compatibility is also a concern when using 120-volt fixtures in RVs, as some RVs may not be wired or equipped to handle the higher voltage.

Safety Considerations
