Show original supplier description
The Colight Y16 Series H4 LED headlight bulbs represent a significant advancement in mini projector bulb technology, offering a breakthrough in both power and performance. Each bulb delivers an impressive 72W and 11,440 lumens on low beam, and ramps up to 144W and 15,840 lumens on high beam, providing exceptional visibility for nighttime driving. Cooling efficiency is paramount with such high power output. The Y16 bulbs utilize an advanced dual copper pipe design in conjunction with dual ball-bearing fans for robust heat dissipation. This system effectively manages heat, reducing light decay and extending the lifespan of the bulbs to over 50,000 hours. The operating temperature range is -40°C to +80°C, ensuring reliable performance in various conditions. Featuring a built-in mini projector, these bulbs produce a sharp, well-defined low-beam cutoff line that enhances road illumination without blinding other drivers. The headlights operate at a 6000K white light color temperature and are compatible with both 12V and 24V systems. A built-in CANBUS driver is included to prevent common electrical issues like flickering or dashboard error messages in modern vehicles. Installation is designed to be plug-and-play, directly fitting into existing H4 sockets. However, these bulbs are only compatible with H4 headlight housings that do not currently have projectors, and require a socket diameter greater than 1.5 inches for a proper fit.
