Is the H11 bulb high or low?

The H11 bulb is a low-beam headlight bulb, typically used in the low beam headlight position of many vehicles. It is a halogen bulb that provides a moderate amount of illumination compared to high-beam headlights.


What is the H11 Bulb?


The H11 is a type of automotive headlight bulb that is commonly used in the low-beam position of many cars, trucks, and SUVs. It is a halogen bulb, meaning it uses a filament heated by an electrical current to produce light. Halogen bulbs are known for providing a brighter, whiter light compared to traditional incandescent bulbs.


The H11 bulb is considered a "low-beam" headlight, which means it provides a more focused, downward-angled beam of light to illuminate the road directly in front of the vehicle. This is in contrast to "high-beam" headlights, which cast a wider, brighter beam to provide longer-distance illumination.


Characteristics of the H11 Bulb



  • Wattage: The H11 bulb typically has a wattage of 55W, though some higher-performance versions may be 60W or 65W.

  • Voltage: H11 bulbs operate on a 12V electrical system, which is standard for most passenger vehicles.

  • Beam Pattern: The H11 produces a focused, downward-angled low-beam pattern to illuminate the road directly in front of the vehicle.

  • Color Temperature: H11 bulbs have a color temperature around 3,000-4,000 Kelvin, providing a whiter, more natural-looking light compared to older halogen bulbs.


In summary, the H11 is a common low-beam headlight bulb used in many modern vehicles, providing a moderate level of illumination for driving at night or in low-light conditions.
