Product Description
The CYT H4 LED Bulb is a high-performance conversion kit featuring a three-sided COB LED pattern that provides 360-degree light distribution. Designed as a “plug-and-play” replacement, it fits into standard H4 sockets common in bikes like the Royal Enfield Classic, Bullet, and Hero/Honda models.
Built with a Die-Cast Aluminum body and an integrated 12,000 RPM Turbo Cool Fan, the bulb is designed for efficient heat dissipation, preventing the overheating issues common with cheaper LEDs. It features dual-intensity modes (High/Low beam) and emits a crisp 6000K pure white light that mimics daylight, significantly improving the rider’s ability to spot road hazards and pedestrians.
Key Features:
-
Superior Brightness: Produces up to 4500 Lumens, offering a much longer and wider light throw compared to stock halogen bulbs.
-
Dual-Beam Functionality: Integrated high and low beams provide a clear beam pattern without blinding oncoming traffic.
-
Efficient Cooling: Uses a high-speed silent fan and aviation-grade aluminum to maintain low operating temperatures.
-
Instant Start: Features 0.1s instant start-up with no flickering or warm-up time required.
-
Weatherproof: Rated IP68 waterproof, ensuring reliable operation in heavy rain and dusty conditions.
-
