In order to have a better view, I had previously installed the Osram Night Breaker Plus bulbs in the car. Which a whiter light than standard bulbs have brought, but I wanted to now even a slightly bluish or cold white light that looks not only looks good, it also provides a good view. Because of Renzesionen I decided for Philips Blue Vision Ultra. (+) The light is very bright (+), It has a slightly bluish tinge on the road, as indicated (+) There are 2 parking light bulbs here that also have a cool white (by the beautiful light is not "ruined" by the sidelights (+) Is the luminous efficiency both in width and length of the forth really very good (similar to Osram bulbs) (+) You look from a distance at the lights (> 20-30 m), it looks Xenon actually very similar (+) Great strength: light (yield and optical) in the dark, best results on the highway without streetlights
(-) If you look from a few meters on the lights, it affects not bluish, but still whiter than standard bulbs (-) At dusk the lights do not look quite as good as in the dark. I can also make no statement about the durability.
Conclusion: The Philips bulbs keep in any case what they promise and see besides a good light yield very chic (although it obviously does not reach Xenon). A strong buy recommendation for anyone who wants to have the good mix of high visibility and thus high safety and visually nice, cold white and slightly bluish light. TOP !!
