Product Specifications

The C21W halogen lamp with a rated voltage of 12V, power of 21W and base model SV8.5-8 is a high-brightness lighting source suitable for low-voltage circuits. C21W is the industry's universal specification code. The 12V rated voltage is perfectly compatible with the electrical systems of vehicles such as cars and motorcycles. With a power of 21W, it far exceeds the C5W and C10W halogen lamps in the same base series, featuring significantly enhanced luminous intensity that meets the needs of scenarios with stringent requirements for light brightness.

Its SV8.5-8 plug-in base has an optimized contact design based on the SV8.5, ensuring a more stable connection and less likelihood of poor contact. It is compatible with special lamp holders, allowing for easy installation and disassembly without professional tools. This lamp is widely used in key lighting parts of vehicles, such as brake lights, turn signals and position warning lights.

In addition, this halogen lamp has excellent color rendering with a color temperature close to natural light, which can clearly restore the details of the illuminated area. Moreover, it has controllable cost and high versatility, making it an optimal choice that balances brightness and practicality in low-voltage lighting for transportation vehicles.
