2pcsPack 35W 3000LM 6500K IP68 Waterproof Car LED Headlight Bulb Features: 1. It uses 16 double-sided ZES-3570 lamp beads, which are brighter than the original halogen bulbs and have a stable light decay. 2. Double-effect integrated heat dissipation, built-in heat dissipation system, equipped with hydraulic fan, the speed can reach 15000RMP, fast heat dissipation, stable fan and long life. 3. Easy to install, plug and play; the surface of the lamp body is sandblasted to improve the mechanical performance of the lamp body, prevent rust and corrosion, greatly increase the contact area between the lamp body and the outside world, and accelerate the heat dissipation of the lamp body. 4. The lamp bead substrate is composed of an ultra-thick aluminum substrate, which has better thermal conductivity and achieves double-sided thermal conductivity. The substrate is closely combined with the aluminum lamp body and fully contacted, which can quickly and efficiently transfer the temperature of the lamp bead to the bottom fan, greatly improving the heat dissipation effect. 5. Built-in temperature control intelligent drive, can identify the temperature of the lamp body and share the heat; avoid the risk of burning the lamp, reduce the temperature of the headlight and extend the life. 6. The use of high-power modules can better adapt to the changes in the instantaneous starting voltage of the car, completely isolate the interference of electromagnetic waves on the car audio and driving computer, making the headlight products more stable and more efficient.
