What they say about CoolBlue vs BlueVision;
Osram Cool Blue
Overall beam: 149.6
An excellent beam pattern with plenty of light at 75m, and more closer to the car. However, three geometric fails cannot be excused, even if it's the sort of problem we'd expect from an OE bulb maker. Not rated
Philips Blue Vision
Overall beam: 149.3
Yet again, Philips is our pick of the blue bulbs It was less 'white' than its rivals, which may explain the better result. It really scores at 75m where its superiority is clear.
