Every time a new headlight lamp comes out on the market, readers send us questions like this: Does the Night Breaker Unlimited really make a difference?

Yes, it does. But even a sophisticated product like this maximum output halogen lamp from Osram cannot bring about a miracle of physics. For this reason, we want to explain here which headlights are most suitable for this newcomer.

Do you get the impression that your light used to be better, for example when your car was new? And does the headlight not have any lenses? In this case, the Night Breaker Unlimited (NBU) is totally in its element. Its technology does best with what are known as reflector systems and clear cover lenses. In this configuration, it can at least bring the gradual loss of light of the headlamps back up to par. In most instances though you can even expect higher performance. The Night Breaker Unlimited’s much colder light enhances this impression even more. This article explains what to consider in evaluating the light.

New headlamps with reflectors also benefit considerably from the technology. But the situation is different with older headlights still equipped with real diffusion lenses, i.e. which do not have a clear cover lens. In these lights, the reflector contributes less to focusing the light on the right spots on the road. But the Night Breaker Unlimited is designed to do just that (for more on this subject, go here). Either way, the new lamp gets closer to the legal limit for luminous flux, meaning ultimately that you do have a slight gain overall.

The situation is similar with projector systems, i.e. lens headlamps. Here the lens and a shutter behind it determine the light distribution, and the NBU cannot fully exploit its capabilities.

High-powered lamps like the Night Breaker Unlimited put up to 100 percent more light at the right spots on the road.

No matter what the scenario, this lamp offers a significantly higher color temperature, which is close to that of xenon light in several models. In other words, if you prefer bluish-white light without compromising on luminous power, then the latest halogen lamp from Osram is your best choice.

It is less recommendable if your car has an above-average operating voltage. Automotive lamps are designed for 13.2 volts. Five percent more cuts the lamp life in half. And for physical reasons this value already is below that of standard lamps. For the latter reason, drivers who always use their low beams during the day can also travel farther with standard or longlife lamps.
