So, are the Osram Night Breaker Lasers any good?
Initial thoughts: they are a noticeable improvement over the OEM Osram H4's fitted.
So trying to be objective, they are brighter, they are 'whiter' or less yellow/orange and the beam pattern/spread also appears to be enhanced.
Driving on unlit rural roads I was happy (for the first time) to drive on dipped beam - I could actually see where I was going - where as in the past with the OEM bulbs as soon as I had the opportunity to switch to main beam I did.
The beam pattern seems to be improved and throws more light on the near side verge, kerb etc. much better than the OEM bulbs.
The colour temp of the light remains on the yellow side of white (as opposed to 'blue' or 'cool' white from Xenons and LEDs) but it is still an improvement over the OEM bulbs.
The 'dark patch' 2metres in front of the bonnet remains but I think this is more to do with the physical positioning of the headlights than the bulb performance.
So would I recommend the Osram NBL? Yes absolutely.
Inherently an 'old skool' H4 filament bulb is not likely to approach the performance achieved with more recent Xenon or LED technology
Would I prefer to have the OEM LED headlamps? Yes absolutely.
Hope this helps!
