De la stanga la dreapta: philips normal, philips blue vision, philips power2night si philips x-treme_power...
Cand o sa vina timpul cred ca o sa ma tenteze x-treme power...
Ce parere aveti?
Hi all,
as I have the pleasure to currently drive at night with the Philips X-Treme Power in H7 version (which I got as a birthday gift from shomoyoque), I wanted to comment on them, and also on some other light bulbs I have experience with.
I own a Skoda Fabia, 2005 model, which has a powerful, yet geometrically a bit "challenging" light, meaning the light beams lack a bit of precision and hence are difficult to adjust, but once this is achieved the light is very powerful for H7 lamps.
I drive a lot on unlit country roads, with a lot of animal crossings (deers, boars, foxes), so I have to rely a lot on my view, that's why I also have untinted windows. Additionally for security reasons I always drive with headlights switched on, at all daytimes. In summer, when I am not driving in the dark, I use Philips or Osram Standard (in Germany around 7-9 EUR per bulb), in order not to waste the expensive special bulbs for nothing.
The switch from Osram Standard to the Philips X-Tremes at first was disappointing. The light colour is the same, hence if you do not have a direct comparison, you won't see a difference. Ok, I fitted one standard back in, and left the X-Treme in the other lamp. Hey, from a first eyesight the X-Tremes looked approx. 50% brighter. Good.
Off to the highways (3 lanes usually). Impressive performance. A Golf V with halogen light passes me, and its light looks a lot weaker. A Mercedes W211 with Xenon light passes, and the X-Tremes can easily compete with the brightness of its Xenon. Of course, the beam of the Xenon lamp is a lot more blueish.
On the really dark country roads the X-Tremes are a killer. The beam is strong and very wide. The geometry of the filament is so precise that adjusting the lights was a sheer pleasure. Result: reflexion poles on the right border are fully lit even in 150 m distance! Especially on wet roads the performance is impressive. The green strips on the left and right of the roads are nicely lit, so crossing animals can be seen early, a lot earlier than with standard lamps.
Ok, enough cheering. After all in Germany these bulbs cost EUR 45 per pair, and one should expect a performance like this. Thumbs up.
Other bulbs I had tested:
Philips Premium: same as Osram or Philips Standard in H7. Reason: the Premium technology already is the standard for H7. Only H1, H3 and H4 lamps profit from the higher inner gas pressure of the Premium's technology. Filament's geometry is a bit unprecise.
Osram Standard: performance like the Philips Premium (due to the aforementioned reason), but a better geometry. Pretty good standard light for a good price (EUR 7-9 per piece, but difficult to obtain some in aftermarket shops)
Philips Blue Vision: Good and white light. Performance similar to standard bulbs, but a lot more white-ish. Colour somewhat between real Xenon and halogen lights. Yet on wet roads, due to higher refraction of the stronger blue part of the light spectrum (caused by the shorter wavelength) visibility quickly deteriorates, but this is an issue it shares with real Xenon. Nice optical effect with only few drawbacks, ok for those who do not like the yellowish halogen light, but for a high price (in Germany 39 EUR per pair).
Osram Cool Blue: stronger than the Philips Blue Vision, with a similar colouring. Same drawbacks on wet surfaces. An even better buy for those who like the white-effect. In Germany sold for EUR 25 per bulb (

doamne!)
My résumé:
If you want power, the Philips X-Treme Power are a good buy. Currently it can't get stronger in H7 in a legal and quality way. The Osram and Philips blue bulbs are ok, but have only standard performance for a high price, but of course the white eye-candy sight
Just out this winter are the Osram Nightbreaker, which with their +90% performance are said to outcompete the Philips X-Treme Power (+80%), but this still has to be proven. Yet the Osram bulbs often outperform the corresponding Philips products in tests, even if only by a hairbreadth.
Sorry for the lengthy text in English (my Romanian just suxx), but I wanted to go into deep a bit.
By the way, the owner of the shop, who provided me with the pics above, admitted that they were obtained using the H4 versions of the bulbs, so they cannot be directly compared with the H7 version, but the result comes close.
And thanks to Mishu/shomoyoque who has provided the object of this test
Greetings,
