Recommended series of halogen lamps: Standard, 100% increment series
 
HELLA is a representative brand of German automotive lighting products, which was the first to launch halogen headlights in 1962, the world's first license for H 4 dual-wire halogen headlamps developed in 1971, and the first generation of xenon lamps in 1992.
 
As a family-owned company, HELLA is a globally listed company with 125 production sites in more than 35 countries and develops and produces vehicle components, lighting technology systems and electronic devices, with a market share of around 12 percent. In addition to Fiat, HELLA supplies a wide range of products to European automakers, and in fiscal 2018, HELLA generated revenues of EUR 3.014 billion.
 
Unlike Osram and Philips, HELLA mainly supplies complete vehicle products in the field of automotive light bulbs, and can only provide a small range of lamp replacement products, only halogen lamps and xenon lamps. For users who want to replace LED headlights, it is recommended to refer to other brands. In the Chinese market, HeLa halogen lamps have two types: standard type and incremental type, which can provide color temperature in the range of 3200K-4000K. In addition, HELLA does not offer UV-resistant coating technology for its halogen lamps, so the lampshades may deteriorate to varying degrees after long-term exposure to halogen lamps. The price of standard halogen lamps is low, only about 30 yuan. The brightening halogen lamp with higher color temperature is priced below 150 yuan for a pair.
 
It is worth reminding that many merchants claim that 4000K is a blue-light type lamp, and even Hella is no exception. In fact, with a color temperature of 4000K, it is far from reaching the spectrum of blue light, not even white light, and the light emitted is the color of yellow light, and the color temperature of at least 6000K is required to emit blue light. Therefore, users need to pay more attention when shopping online. In addition, although the color of blue light is cool, it has low penetration, and the light is scattered seriously in rainy and foggy weather, which may affect driving safety, so it is not recommended for users to choose lights with a color temperature higher than 6000K.
