There are a lot of Chinese fakes available in market. Please double check and confirm that the bulbs are genuine before you buy. Here is my little knowledge on identifying a fake. (I went to 6 accessories showroom 2 weeks back looking for the bulb. Below points are conclusions made with my own experience and with inputs some genuine showroom people I can believe)
1. Base: Color of the base will will have a very slight copperish tint while fakes will have a bluish iron tint.
2. Embossing: Original bulbs has base type, volts, wattage and country of manufacturing embossed starting with Philips. I identified fake ones just by checking these embossing. None of them has this and some had some data printed in black color.
3. Xtreme Vision bulbs imported to India are Either made in Germany or Poland. Origin country is always embossed on the base of the bulb. Fake ones will not have these.
4. There is a blue ring just below the reflective tip. Fake ones will have this just painted.
5. Always buy these kinds of electrical components from any reputed dealers.
Above are just my observations. I am no expert in auto parts or electricals. But i keenly observe everything before I buy. Experts can correct me if I am wrong.
Thanks hobeezz for those wonderful pointers. They are definitely to look out for while buying a new EV bulb. Although I have been using these bulbs for few years now, I never bothered to look for all of them except only the hologram (which can be duplicated easily). Good to realize that I was lucky enough not to have been duped all these years partly because I always bought these from a Philips authorized distributor in Bangalore.
Here is my little bit on both the bulbs being compared here.
I have been using both Philips Extreme Vision (previously Xtreme power) and Osram Night Breaker plus (previously Night Breaker) on my cars & bikes for past five years (no relays & wiring harnesses for me). I would like to share my personal experience with both bulbs which might be of help to fellow members... Osram Nightbreaker Plus:
These bulbs are brighter & whiter compared to stock bulbs. Although they claim a 40m longer beam and 100% more light on road in reality I feel the improvement is not more than 35-40%. They throw a more bluish light (color temp 3900K) compared to their Philips counterpart. Their life also seems to be shorter compared to the Philips ones. Cost also is marginally lower than the Philips ones. I had started off with Rs 650 a pair and now I believe they cost anywhere between 900 to 1100. With their chrome tip these bulbs however look very stylish when your headlight is off (of course if you have a transparent lens). Philips Extreme Vision:
Same amount of throw and light as compared to NB Plus. The light is more whitish (read less bluish - color temp 3500K) compared to the NB Plus. Gives better visibility in rains and fog. Longevity is more compared to the NB Plus. Cost is marginally higher - around 1150-1200 for a pair.
Currently I have Extreme Vision installed both for my Headlamps (H4) & Fog lights (HB4 9006). Given an option I would personally prefer the Philips Extreme Vision, reason being they don't blow out easily and they have a lower color temperature - better for bad weather. Why didn't I go for a 90/100 setup?
To be very frank, I am scared & apprehensive. Scared that the heat would damage my lens and assembly. Moreover (being from the electrical background) I believe higher power would draw more current through the electrical system (8.33 amps vs 5 amps) which I feel might be detrimental to the car's electrical system in the long run. Our cars are built for a 55/60 kind of assembly. If the electrical system can support 90/100 setup, the manufacturers themselves would have installed 90/100 bulbs. Today's cars are so highly dependent on the electrical system & electronics; the last thing I would like to do is fiddle with the electrical system. This is just my reasoning; I would prefer to leave this to the experts though.
Whichever bulb you choose, just make sure you always keep a working spare bulb of the same variant always with you. These are kind of premium products and very few people stock them. You might not be able to find one in some remote town (or even city) when on a long drive away from home.
Another point almost always missed out is the head-light alignment. I would recommend getting the alignment checked and adjusted through a qualified professional at least once every six months. Most of the 'less & pathetic light' issues get addressed considerably after getting proper alignment done. I know of a friend complaining about the pathetic light from his Figo headlamps for almost a year until one day I got his headlamps aligned at a service center. Now he is pretty happy even on the stock bulbs...
