LB4-FU3 LED Headlight Bulb Kit H4 3000K

[Product Information]
Light bulb color (halogen color) 3000 Kelvin specification LED headlight bulb
■By efficiently releasing the heat generated by the LED, the LED can always be lit at full power!
LEDs are characterized by their extremely high conversion efficiency (the efficiency of converting input power into visible light [electromagnetic waves with wavelengths that can be seen by the human eye]), but even so, if the input power is 100%, more than 70% is converted into heat.
The Cyclone LED series uses a combination of solid aluminum, a heat sink, and a waterproof cooling fan to efficiently dissipate heat and enable full power lighting at all times.

■Waterproof cooling fan
Thermal management is essential for heat-sensitive LEDs.If this heat cannot be dissipated efficiently, the power must be reduced from the start of lighting or from the middle of lighting.
In other words, if you don't have a good thermal management system, you can't get the full potential of LED.

■Adopts a highly durable waterproof fan!
In the Cyclone LED series, Protec also paid attention to the fan which plays an important role in cooling the heat generated by the high power LED efficiently.
The fan used for general electronic equipment is not suitable for motorcycles because the bearing of the rotating part is "metal support type" and durability is low.
The Cyclone LED series uses a "dual axis ball bearing type" bearing with waterproof performance and excellent durability, which is also used for cooling fans of radiators.
It may look small, but it has passed the 20G seismic test for 2 hours!Protech is the only LED bulb for motorcycles that uses a waterproof and durable fan.

■Available color temperatures are 6000K and 3000K
Please select your favorite color from two colors: 6000 Kelvin, which is a typical LED blue-white color, and 3000 Kelvin, which is a classic halogen bulb color.




■Long life!
It has a longer life than HID as well as stock halogen bulbs.

■Power-saving design!
Power consumption is 30W for H4 / H4-R type and 20W for H7 type, so it is more energy saving than general H4 halogen bulb (12V 55 / 60W).

Adoption of reliable CREE's LED!
Durable and reliable CREE XLamp XP-L LEDs are used for the light emitter.

■Hi / Lo switching!
H4 / H4-R type has 3 LEDs for Hi beam and Lo beam respectively and Hi / Lo switching is available.

■Easy to install!
It is easy to wire by replacing the valve coupler.

■Bright and quick lighting!
Unlike HID, it lights up with full power immediately after power-on.Also, the color of the light does not change gradually like HID.

[Questions and Answers about fitment and installation]
Q. Is it possible to combine another manufacturer's LED bulb and Protec's H7 Hi/Lo LED to light two Lo beams?
A. Yes, you can.Please see this blog for an explanation.

Q. There is a fan at the back of the LED bulb, are there any requirements for the installation space?
A. If you have an H4 bulb or an H7 bulb + H4 adapter, you need to have at least 20mm of space behind the headlight harness coupler.

Q. I can't install the fan on my naked bike because the fan hits the headlight case.
A. Drill a hole of 60mm in diameter in the headlight case where the fan will hit.

Q. Is it possible to cool a naked bike without a hole in the headlight case if the fan can turn?
A. If the headlight is installed in a headlight case that does not have a hole and is almost sealed, such as DUCATI or Harley, the heat generated by the LED cannot be exhausted by the fan, so please make a hole in the headlight case for exhausting heat.Two or three holes with a diameter of at least 20mm are required.

Q. Is it possible to install a model that is not listed in the compatibility chart on the Protec website?
A. If we have not confirmed the installation of the product on an actual bike, it is not listed in the compatibility chart, but it may be possible to install it on some bikes.

[Q & A on performance]
Q. What is the lumen rating of Pro-tek's LED bulbs?
A. H4 30w is 2, 940 lumens and H7 20w is 1, 960 lumens.The stock bulb is about 1, 000 lumens at 55w, and 600-700 lumens at 35w, so it is several times brighter.

Q.Which is brighter than HID?
A. General 35w HID is 2, 600-2, 700 lumen, so 30w LED is brighter in lumen value.

Q. What is the difference between lumens, candelas, and kelvins?
A. Lumen is the total amount of light emitted in all directions, and candela is the luminous intensity (the intensity of the light source in one direction).

Q. How long is the lifespan of the product?
A. The CREE LED chip used in Protech is about 20, 000 hours, and the electric fan is about 10, 000 hours.If the light is used for 1 hour each way for commuting 5 days a week or 8 hours for touring on weekends, it will last about 10 years.
*The above times are approximate and may not necessarily match the actual usage conditions.

Q. Isn't the fan easily broken?
A. The electric fan used by Protech is of the same design as the radiator fan, which is waterproof and shockproof.It is similar in shape to a fan used in a computer, but is completely different.

Q. How much power does it save compared to stock valves?
A. The stock bulb for H4 and H7 is 55w, so it saves 25w compared to LED H4, and 35w for H7.In the case of the NinjA1000 with one H7 Lo beam, the power consumption of two LED Lo beams is 15w less than that of one Lo beam with a stock bulb.

Q.Why does the H7 Hi/Lo LED bulb on the Hi beam side produce a Lo beam?
A. When the headlight on the Hi beam side is turned on Lo, the illumination height is the same as that of Lo beam.However, the reflector structure of the Hi side and Lo side headlights is different, so the irradiation angle is the same height as the Lo side due to the characteristics of Hi beam irradiation.






A. The maximum luminous intensity at Hi-beam measured by the inspection machine must be 15, 000 candela or more, the optical axis of the maximum luminous intensity must be within the standard frame, Hi/Lo must be switched by the inspector's eyes, and the emission color must be white.

Q. I received a failing grade in the headlight inspection
If you report LED headlights during the headlight inspection and the inspection machine is not compatible, please retest on an inspection line with a compatible tester.In case of rejection, please check the reason such as faulty optical axis adjustment or insufficient maximum luminous intensity, and adjust the lens.


There have been cases where two-light headlights were rejected because only one side switched to Hi beam.


A. The Lo beam side headlight has a reflector structure that does not produce the same maximum intensity as the Hi beam side headlight.Even if Hi and Lo are actually switched correctly, the standard value of 15, 000 candela is not achieved due to the difference in reflector performance.Please cancel the Hi/Lo switching function of the LED bulb on the Lo beam side when you inspect your bike.

[Q & A on glitches]
Q. The light was white at first, but now it has turned yellow
A. For some reason, the cooling is not working properly and the LED chip is damaged by the heat.

Q. The fan does not work.
A. The fan is always rotating when the power is on.

Q.I installed H7 Hi/Lo, but the two Lo beams do not light up.
A. The brown wire of the controller harness on the Hi beam side may not be connected to the (+) wire on the Lo beam side.
