D4S 4300K are high-quality xenon automotive bulbs with 15% increased brightness compared to original Osram or Philips bulbs. Designed to replace burnt-out bulbs in vehicles with factory-installed xenon lighting. Available at a price of 35 EUR per piece or 60 EUR for a set of 2 pieces.
We strongly recommend installing xenon bulbs with a color temperature of 4300K (Kelvins). Here are the main arguments in favor of this choice:
- All European car manufacturers equip their vehicles with bulbs of exactly this color temperature at the factory.
- In many European countries, the use of bulbs with a color temperature above 5000K is prohibited.
- The 4300K temperature corresponds to the brightness of morning, pre-noon sunlight, while 5000K is the maximum brightness of summer sun at noon, which distorts the real color of objects, leading to brain strain when assessing dynamic surroundings.
- The human brain most comfortably perceives objects illuminated at night with 4300K light, as in daylight: grass remains green, old asphalt remains gray, new asphalt remains black. Other color temperatures do not convey true colors, causing tension, discomfort, and rapid fatigue.
- Light intensity, measured in lumens, reaches its highest values precisely at a color temperature of 4300K.
For clarity, here is a comparative table of color temperature vs. brightness:
| Bulb Type / Power | Color Temperature | Brightness (Lm) | Light Color |
|---|---|---|---|
| Halogen Bulbs (55W) | 3000K | ~1500 Lm | Yellow |
| Xenon Bulbs (35W) | 4300K | ~3200 Lm | Warm White |
| 5000K | ~3000 Lm | Cool White | |
| 6000K | ~2400 Lm | White with Blue Tint | |
| 7000K | ~1800 Lm | Blue | |
| 8000K | ~1500 Lm | Blue-Blue |
As can be seen from the table, the brightness of xenon bulbs at 4300K is more than twice that of halogen bulbs (increase ≈100%), while power consumption is 26% lower.
Let us also debunk a common myth: some believe that the heating temperature of headlights with xenon bulbs is significantly lower than with halogen bulbs, and therefore the reflectors of xenon optics burn out less. This is not true. Reflectors burn out in both xenon and halogen optics due to long-term use. The difference in heating is negligible: the filament temperature of a halogen bulb (55W) is about 410°C, while that of a xenon arc is 390°C, a difference of only 5%.
Our D4S 4300K bulb provides not only increased brightness and compliance with European standards but also an optimal light spectrum for the eyes, making night driving safer and more comfortable.
