LED bulb Masuma, H15 5/18W 6000K 3000Lm PGJ23t-1, L635

Specifications:

Exact OEM Fitment

Masuma LED headlight bulbs are designed to precisely match the dimensions of standard OEM halogen bulbs, ensuring straightforward installation without modifications.

Maximum Brightness

LED bulbs significantly outperform conventional halogen counterparts, delivering up to 60% more light output. This results in brighter, clearer, and more uniform road illumination, improving both driving comfort and safety at night.

Proper Light Distribution

Masuma LED bulbs use modern SMD (Surface Mounted Device) chips, offering several key advantages:

• High luminous efficiency: 50–100 lumens per watt with lower power consumption, reducing load on the alternator.
• Wide beam angle: ensures even light distribution.
• Vibration resistance: SMD chips are soldered directly onto the board, providing excellent durability under constant vehicle vibration.

Cool White Light

With a color temperature of 6000K, the light closely resembles natural daylight and reduces eye strain. The human eye is more sensitive to cooler light in low-light conditions, improving visibility of the road, lane markings, and signage, and making nighttime driving more comfortable.

Sealed Housing

The bulbs feature an IP65 protection rating, ensuring high resistance to dust and moisture. This guarantees reliable operation even in harsh environmental conditions.

Active Cooling

All Masuma LED bulbs are equipped with an active cooling system, including:

• an aluminum housing with an advanced heat sink,
• a built-in low-noise fan,
• a thermal interface layer between the LEDs and the heat sink.

Long Service Life

Efficient cooling prevents overheating — the main cause of LED degradation. As a result, Masuma LED bulbs provide consistent light output throughout their entire service life of up to 50,000 hours.

CAN Bus Compatibility

All bulbs feature a built-in CAN bus decoder to prevent “check light” errors and flickering in vehicles with onboard diagnostics systems.

Please note: 100% compatibility is not guaranteed, as the integrated module may not work with all vehicle ECUs. In rare cases, incorrect operation may occur. This is not considered a warranty issue; however, the bulbs can be returned if they are not compatible with your vehicle.
