Halogen h4 bulb

Types of Halogen H4 Bulb

The Halogen H4 Bulb is one of the most popular headlight bulbs on the market. It has a dual filament design. A 60/55 watt bulb is used for low and high beams. The 12-volt H4 halogen light bulb is said to be brighter than its predecessors, the H1 and H2. It is available in various types, including the H4 6000K, H4 4300K, H4 5000K, and H4 8000K. The numbers on the H4 bulb represent the color temperature in Kelvin. The higher the number, the whiter and brighter the light. There is also a set of H4 halogen headlights with different color temperatures.

• H4 6000K Bulb: The H4 6000K bulb produces bright and white light. Some models also have an ice blue tint that enhances the bulb's aesthetics.
• H4 4300K Bulb: The H4 4300K bulbs generate bright white light with a slight yellowish tint. They are very bright and improve visibility on the road.
• H4 5000K Bulb: The H4 5000K halogen bulbs are quite rare. They produce bright white light, but not as bright as the 6000K bulbs.
• H4 8000K Bulb: The H4 8000K bulb emits a super bright blue-white light. The visibility is excellent, but it may glare or blind oncoming drivers.

The standard H4 halogen headlight bulb has a power of 60/55 Watts. However, there are other wattage variations for more powerful and brighter lights. Some non-standard H4 halogen bulbs have a power of 75/70W.

Specification and Maintenance of Halogen H4 Bulb

These are some important factors to consider when buying an H4 halogen bulb:

• Wattage

  The wattage of an H4 halogen bulb is 60/55 watts. The bulb has 60 watts for the high beam and 55 watts for the low beam.

• Color temperature

  The color temperature of an H4 halogen bulb is 3200K. This temperature creates a warm white light that is similar to incandescent light bulbs.

• Lifespan

  The average lifespan of an H4 halogen bulb is between 500 and 1000 hours. This is lower than the lifespan of other types of headlight bulbs.

• Socket type

  The socket type of an H4 halogen bulb is P43t. This socket type is used to connect the bulb to the vehicle's electrical system.

• Voltage

  The voltage of an H4 halogen bulb is 12 volts. This voltage is required to power the filament inside the bulb.

It is important to maintain the H4 halogen headlights to ensure optimal light output and longevity. Here are some maintenance tips:

• 1. Regularly clean the headlights to remove dirt, grime, and bugs. This will improve visibility and safety when driving at night.
• 2. Inspect the headlights regularly for early signs of bulb failure, such as dimming lights or uneven light distribution.
• 3. Always handle H4 halogen bulbs with gloves or a clean cloth. This prevents oils from the skin from getting on the bulb's surface. The oils can cause hot spots that shorten the bulb's lifespan.
• 4. Replace bulbs in pairs to maintain balanced lighting. This is because one bulb may be close to failure if another one is.
• 5. Use only H4 halogen bulbs that are compatible with the vehicle. This is important because the bulbs have different wattages and socket configurations.

How to choose halogen h4 bulbs

With lots of choices on the market, it can be daunting to choose the right halogen H4 headlights for one’s needs. Here are some factors to consider while selecting an H4 halogen bulb:

• Brightness

  Normal brightness is 1300lm for low beam and 1300lm for high beam. This is standard for most H4 halogen bulbs. The super brightness option is 1600lm for low beam and 1600lm for high beam. These produce brighter light, which is useful for driving in dark conditions.

• Color temperature

  There are two options to choose from: 3200K or 4000K. The 3200K color temperature produces a warm white light. The 4000K color temperature produces a cool white light. The choice depends on personal preference.

• Rated life

  The lifespan of an H4 halogen bulb is measured in hours. The standard-rated life is 2000 hours. The super-rated life is 3000 hours. This means the super-rated life bulbs will last 1000 hours longer than the standard-rated life bulbs.

• Voltage

  The halogen H4 bulbs have a voltage of either 12V or 24V. The 12V bulbs are used for most cars. The 24V bulbs are used for heavy-duty vehicles.

• Wattage

  The halogen H4 bulbs have a wattage of either 60/55W or 100/60W. The 60/55W bulbs are used for most cars. The 100/60W bulbs are used for heavy-duty vehicles.

How to DIY and replace Halogen H4 Bulb

Q and A

Q1: Are H4 halogen bulbs dual-beam?

A1: Yes, the H4 halogen bulbs are dual-beam. They produce both high and low beam lights. The high beam is brighter and more focused, while the low beam is wider and less intense.

Q2: Can I use an H2 or H7 bulb instead of an H4 bulb?

A2: No, if a vehicle requires an H4 bulb, it should not be replaced with an H2 or H7. The H4 bulb has a different base and wiring configuration compared to the H2 and H7 bulbs. Always use the correct type of bulb for the vehicle to ensure proper fit and functionality.

Q3: What is the average lifespan of an H4 halogen bulb?

A3: The average lifespan of an H4 halogen bulb is between 500 to 1000 hours. However, factors such as frequent on-and-off switching, vibrations, and extreme temperatures can affect the lifespan.

Q4: Are H4 halogen bulbs suitable for all vehicles?

A4: No, not all vehicles are compatible with the H4 halogen bulbs. While many cars, especially older models, use this type of headlight bulb, some newer models or motorcycles may require different types. Always check the vehicle's manual or existing bulb type before purchasing.

Q5: Can H4 halogen bulbs be used for fog lights?

A5: Yes, H4 halogen bulbs can be used for fog lights, provided the fog light housing is compatible with the H4 bulb. However, there are specific bulbs designed for fog lights that produce a more suitable color temperature.
