Many people are unaware, Osram is a leading German manufacturer of electricals and automotive lighting. They are a leading brand in several countries and have a brand history of over 100 years. They are OEM suppliers for many leading automobile brands.
I am using their aftermarket halogen headlamps( Osram Nightbreaker Unlimited) which is brighter than standard 55w halogen headlamps and has a very even beam spread. The bulb has a light blue coating which makes the bulb appear whitish when glowing, but the beam color is yellowish white.
Overall great products and great range.
