Since the 1990s, xenon bulbs have become increasingly common among car manufacturers. Initially reserved for high-end cars, they now equip many vehicles. There are different types of xenon bulbs with specific characteristics that will need to be checked when replacing them. Here is a guide to help you choose the model perfectly suited to your vehicle and the brand that will meet all your expectations.
What are the different types of xenon bulbs?
When you are looking for a xenon bulb for your headlight you have to choose between many models. Beyond the brand you choose, there is a precise nomenclature that helps you navigate.
First, you will always find a D which stands for "Discharge", recalling the operating principle of these Xenon bulbs which are discharge lamps. Then, there is a number ranging from 1 to 8 indicating whether the base is separate or integrated, as well as its reference. Finally, a last letter indicates whether the bulb is intended for a reflector or projector headlight. The gas pressure inside the bulb can also vary from one model to another. In all cases, strict regulations must be observed for insurance purposes, and we invite you to check which model is recommended by the manufacturer, or even to contact a professional who can guide you.
| Category | Base Reference | Voltage / Power | Headlight type | Base |
|---|---|---|---|---|
| D1R | PK32d-3 | 85 V / 35 W | Reflector | Integrated |
| D1S | PK32d-2 | 85 V / 35 W | Projector | Integrated |
| D2R | P32d-3 | 85 V / 35 W | Reflector | Separate |
| D2S | P32d-2 | 85 V / 35 W | Projector | Separate |
| D3R | PK32d-6 | 42 V / 35 W | Reflector | Integrated |
| D3S | PK32d-5 | 42 V / 35 W | Projector | Integrated |
| D4R | P32d-6 | 42 V / 35 W | Reflector | Separate |
| D4S | P32d-5 | 42 V / 35 W | Projector | Separate |
| D5S | PK32d-7 | 12 V / 25 W | Projector | Integrated |
| D6S | P32d-1 | 42 V / 25 W | Projector | Integrated |
| D7S | PK32d-1 | 42 V / 25 W | Projector | Integrated |
| D8S | PK32d-1 | 12 V / 25 W | Projector | Integrated |
Beyond these characteristics, xenon bulbs differ in their color temperature, which generally ranges from 4300K to 6000K (white light with some blue nuances).
Compared to conventional bulbs, xenon bulbs offer:
- a lifespan 3 to 5 times longer
- illumination 3 to 5 times greater at equivalent power
- lower power consumption and heat dissipation
Why choose Bosma xenon bulbs?
While many renowned manufacturers offer a wide range of xenon bulbs, the question of selecting more affordable products like those offered by Bosma is legitimate.
Bosma is a brand little known to the general public but which is a reference for many professionals. It offers xenon bulbs that can perfectly replace those produced by other manufacturers such as General Electric, Philips, or Osram.
Bosma manufactures the most popular categories of xenon bulbs, namely from D1 to D4, in versions for projector (S) and reflector (R) headlights.
In addition, Bosma systematically offers two color temperature options, with 4300K or 6000K, as you prefer. Depending on your preference, you can therefore choose a more or less white light.
Like other manufacturers, Bosma subjects its bulbs to advanced tests and meets all existing standards, including the very strict ECE - R37. Compliance with these standards ensures sufficient power to illuminate your surroundings in low beams (at least 30 meters) and high beams (at least 100 meters).
If your xenon bulbs do not comply with these standards, you risk not being covered by your insurance in the event of an accident. Similarly, if the bulbs are improperly installed (incorrect orientation or inclination), they could, for example, dazzle other drivers and engage your responsibility, in addition to exposing you to a fine in the event of a check.
In the same vein, we recommend always changing the xenon bulbs in both your headlights at the same time because the color temperature can change over time. This difference can be annoying as it will alter your perception of your surroundings.
In conclusion, choosing Bosma xenon bulbs will allow you to meet the strictest standards while managing your budget.
