Headlamp bulbs are now changed to Osram Night Breaker Laser 60/55w ones.
Low beam Lumens have increased considerably. Low beam Kelvin seems to be similar.
High beam Lumens are almost same as earlier, but Kelvin have increased considerably. High beam is slightly bluish now.
With recent rains in Delhi and around, low beam worked brilliantly but the high beam as expected performed very badly due to high Kelvin i.e., bluish color.
I had used these earlier in WagonR, so am aware of the low life of filament and poor high beam quality. I have a spare Philips Xtreme Vision with me, and was using that in my right side headlight for last 15 days. The overall difference is negligible, and like earlier it got proved again that ONBs are very good in low beams but have a shorter life time with poor high beam quality. Whereas, PXVs are same in low beam as standard halogens from Osram/Philips; but quite better in high beam than ONBs and standard halogens. Plus, these PXVs are having a very long life in comparison to ONBs. Although not as long as standard OEM halogens, which are immortal!
Conclusion:
No need to replace from OEM halogens until you are ready to sacrifice your peace of mind. If you really want brighter lights to assist you in night driving, either go with PXVs or upgrade your bulb wattage to 100/90w with proper relay and wiring upgrade thrown in.
I'll be soon posting a video of ONB Lasers in action. Stay tuned.
