Upgrade Factory Halogen Bulbs

Upgrade your factory halogen bulbs to LED bulbs. IPF offers a new entry model series "Effecter LED Head & Fog Lamp Bulbs."
IPF is now offering LED head and fog lamp bulbs as a new addition to its LED products' entry model series "Effecter."

Effecter LED head and fog lamp bulbs are available in two color temperatures of LED light, offering 6500k daylight color and 2600k deep yellow color. IPF's specifically designed deep yellow light color provides improved road visibility in adverse weather conditions.
Incorporated a built-in drive unit in all-in-one body assembly bulbs, Effecter LED bulbs are almost identical size to factory halogen bulbs, made them smaller than existing LED bulb products.
Equipped with a small waterproof electric cooling fan in pursuit of the ultimate balance between brightness, temperature control and cooling performance. Various tests and countermeasures, including waterproof, vibration and shock tests, are carried out to ensure basic reliability as entry model products.

IPF offers basic entry model bulbs for all drivers, ensuring safe and secure visibility when driving at night. Easily upgrade from factory halogen bulbs to the Effecter LED bulbs, offering low power consumption and wide-range illumination.

Identical Size to Factory Halogen Bulbs

New Effecter series' LED bulbs are identical size to factory halogen bulbs, which allows for installation in pop-up headlamps and vehicles where rear of larger IPF LED bulbs tend to come in contact with vehicle parts due to limited clearance.

New Features Added

Incorporates IPF's unique optical technology, ATS – Asymmetrical Top Shade, reduces glare light to oncoming traffic and provides wider beam to pedestrian side for clearer visibility (H4 type).
Increased reliability provided by optimal temperature control through use of a small-sized waterproof electric cooling fan and patented technology, LACH – LED Air-Cooling Hole, for improved heat release (H4 type).

Built-in High Beam Indicator Lighting-up Circuit

Incorporates the built-in high beam indicator lighting-up circuit, which solves an issue of compatibility with some vehicle models using factory halogen bulb. If the circuit is not built in LED bulb, your vehicle's high beam indicator on the dash may not work properly.
*Old model year vehicles (no compatibility with LED bulbs) may additionally need the optional high beam indicator lighting-up circuit. Part number: WA-4.

Various Tests and Measures to Ensure Basic Quality

Pre-production tests were carried out prior to product launch on electrostatic resistance, surge resistance, overvoltage, vibration resistance, continuous lighting, heat resistance, water resistance, dust resistance, etc. Furthermore, waterproof measures were added and released into market. Basic quality as an entry model product is ensured.

///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.
