Three bulb types are available to match different needs: halogen, xenon HID, and LED. - Halogen: economical option with lower brightness and shorter lifespan. - Xenon HID: high brightness with lower power consumption, but higher cost and a longer warm-up time. - LED: fast response, low energy use, long life, and increasingly the mainstream choice. Key benefits - Flexible options to balance brightness, efficiency, and durability in a single product. - Clear trade-offs so you can choose the right bulb for the application. - Long-term value through improved efficiency or extended life depending on the option chosen. 2-3 practical use scenarios - Automotive headlights: select LED for longevity and instant-on performance, HID for maximum brightness, or halogen for budget-friendly replacements. - Outdoor lighting: LED for efficient, long-lasting area lighting; HID for very bright outdoor illumination where power is available; halogen as a lower-cost alternative. - Indoor/showroom lighting: LED for quick response and long life in display or task lighting environments. Designed to provide function, performance, and options without compromising reliability.
