Philips Diamond Vision H1 (Twin)


Why buy me?

If you’re looking for headlight bulbs that offer a bright white light, look no further. These Philips Diamond Vision H1 bulbs are the perfect option and are the closest styling match to HID Xenon bulbs. The deep blue coating on these Diamond Vision bulbs creates the ultimate white light with a slight blue tint.

Features and benefits

  • The colour temperature of these bulbs is 5000K
  • The colour and brightness of the headlights in the visual is not an actual representation of Philips headlights
  • The whitest upgrade available
  • The Philips Diamond Vision bulb does not offer a greater light output but provides a white light for enhanced styling
  • Philips Diamond Vision H1 Bulbs are not road legal in the EU

PLEASE NOTE: The standard unit for colour temperature is Kelvin (K). Brightness is measured in lumen. Standard halogen bulbs produce yellow light at 3200K. Xenon HID technology produces white light at 4200K. The colour temperature for bluish white light is 5000K. The colour and brightness of the headlights in the visual is not an actual representation of Philips headlights. The Philips Diamond Vision range is not road legal in the UK. Philips Diamond Vision car bulbs do not comply with ECE R37 regulations and are not road legal.

3Headlight H1 bulbs

The H1 bulbs gave a nice white light but not a bright beam. Not good in rain or poor visibility.

5Good white light.

These bulbs are very nice. They produce a nice white light which is very bright. They are fitted to my main beams on my bi-xenon bulbs so I can't really comment on how effective they are on there own but combined with my xenons on full beam they illuminate the road really well. I would recommend.

5Philips Diamond Vision

I am satisfied with the Philips Diamond Vision bulbs. I don't need to spend hundreds to convert to HD and have a similar HID effect on the low beam. I was worried about the glaring but it turns out the low beam light is pointing downward enough it does not blind the other drivers.

5The Go To bulb supplier

I use PowerBulbs for all my bulb requirements and have never once been disappointed with either product quality or speed of service.
