Market-leading IPF LED headlamp bulb series has evolved as the F series. Designed to fit a wide range of vehicles with limited installation clearance.
IPF offers downsized space-saving H11 and HB3/4 type LED bulbs incorporating great new technologies including high-efficiency cooling performance of LEDs.
The new F series LED bulbs are developed to provide all time high lighting performance.


• Designed to deliver minimum bulb size and utmost light output
• Downsized LED bulb body allows installation in limited clearance
• Compatible with a wide range of vehicles using headlamp protective cover
• Maximized light output giving of IPF's accumulated knowledge and key technologies
• Enhanced lumen maintenance so as to maintain LED bulb's initial light output and brightness
• Offering a proper beam pattern and bright illumination

Improved Compatibility

New F series' downsized body LED bulbs allow installation in limited clearance and vehicles with headlamp protective cover.
Improved compatibility offers an additional option to many users.

* In some cases (vehicles), LED bulb's drive unit needs to be placed outside of the headlamp unit. In that case, refer to the installation manual and make a hole in the cover or headlamp unit. Also pass the LED bulb's harness through the cover or unit and waterproof it.
• This product is designed for headlamp bulb upgrade
• Misuse may result in technical malfunction

Developed Optimum LED Light Distribution

Downsized body LED bulb, with its high intensity far-reaching strong light and built in small-sized cooling fan, has been further developed with a number of new technologies, including improved lumen maintenance while ensuring greater reliability. IPF's new F series bulbs deliver perfect light distribution for safer and more comfortable night driving.

Improved Road Visibility

Replicates halogen bulb filament, providing 6500k true white daylight color. Improved road visibility ensures safety night-time driving.

Three Key Technologies

IPF brought the all-new three technologies into the F series LED bulbs. Enhanced heat release design to offer the best and brightest
lighting performance. The thinner LED bulb body, the better light pattern can be made. The thicker LED bulb, the better heat release
efficiency can be achieved. IPF's performance LED bulbs can balance excellent light distribution characteristics with outstanding
brightness. 4600 lumen in total flux (conventional ratio128% UP) is a sizable improvement in lighting performance.

• IPF's performance LED bulbs feature the most efficient method for heat release
• Adopts our patent technology, "Dual CPS"
• Advanced manufacturing technology "Post Structure" provides high-spec copper substrate
• "Dual CPS" delivers thin structure of LED bulb body and conducts heat given off from LED circuits to the heatsink

Technology 2 "Highly efficient Heat Conduction & Release Design"
• Highly heat-conductive aluminum die-cast alloy LED body
• Proven reliable heatsink using extruded aluminum alloy A6063
• Optimized heatsink shape ensures enhanced heat release efficiency

Technology 3 "Top Performance large-sized Electric Cooling Fan"
• Optimized heatsink incorporating large-sized cooling fan
• Increased wind power and reduced wind noise by fluid analysis
• Large volume of air delivered ensures the LED bulb runs cooler

///Term description///
Lumen It is the unit of the optical energy generated from an electric bulb.
When numerical value is large, the brightness of the bulb become brighter.
Candela Measure the brightest point numerically when a head lamp is equipment.
kelvin Kelvin temperature is a numerical measurement that describes the color appearance of the light produced by the lamp and the color appearance of the lamp itself,
expressed on the Kelvin (K) scale.

Light source
Halogen Halogen light bulbs are a special type of incandescent light bulb.
They are filled with halogen gas, have a tungsten filament, and are enclosed in quartz glass.
It is intend to be out of date, but still bright and gentle light in the eyes.
H.I.D High Intensity Discharge, it the new replacement technology for halogen headlights.
Brightness is the biggest advantage of an HID conversion. Not only will you be able to see farther and better at night, but other drivers will be able to see as well.
Its estimated that an HID conversion kit will increase your brightness from a halogen set up as much as 300%.
LED LED lighting is a lamp or other light that uses light-emitting diodes (LEDs) as a source of illumination.
LEDs are more expensive than traditional bulbs. They are heat sensitive, so if they are not used with a steady and consistent current, they can stop working or fade quicker.
These lights are also usually best used in directional lighting rather than room lighting, although some changes in design may improve this.
