Super Bright H4 LED Fog Light Bulb 12V 20W Zinc Alloy Kit
Construction and Thermal Management
This H4 LED fog light uses a zinc alloy housing instead of the more common aluminum designs. Zinc alloy offers good vibration resistance, which is relevant for components mounted low on the vehicle where road shock is more pronounced. The material also aids heat dissipation: the housing draws warmth away from the internal driver circuit, allowing steady operation without active fan cooling. Rated lifespan is quoted at approximately 50,000 hours under normal use.
Specifications
| Housing Material | Zinc alloy (corrosion-resistant treatment) |
| LED Chip | 3570 high-density array |
| Color Temperature | 6000K white (3000K amber or 3500K warm white available) |
| Power Draw | 20W actual operating wattage |
| Lumen Output | 2600LM |

Beam Control and Road Performance
A vertical metal ridge is positioned next to the 3570 chip to cut off upward light scatter. In foggy or snowy conditions, uncontrolled light can reflect off moisture particles and reduce usable vision. This shield directs the majority of the 2600LM output toward the road surface and shoulders, helping the driver see lane markings and curb edges while keeping glare away from oncoming traffic. The beam pattern works with the vehicle's existing reflector housing, so no optical modifications are required.
Application and Color Options
This H4 LED fog light is suitable for replacing older halogen bulbs in front bumper positions. It is offered in three color temperatures: 6000K white for a clean modern appearance, 3500K warm white, and 3000K amber-gold for regions with frequent heavy rain or dust. The choice of spectrum allows drivers to match the light to their typical weather conditions without changing the hardware itself.
Socket Variants and Ordering
Although the current version uses an H4 base, the same housing and chip layout can be produced with other common socket types, including H1, H3, H7, 9005, 9006, H8, and H11. This allows retailers to stock one product family across multiple fitments. Custom color temperatures and printed packaging are available for bulk orders, with minimum quantities kept practical for smaller online sellers. Direct factory sourcing eliminates distributor markups, and logo laser-printing or box design services can be arranged at the time of order.
