A cheerful Hello everyone, I'd like to make it clear with this shit client recessions in the field Osram. I think as a foreman in the field of electrical engineering I like operation requires enough experience with lighting technology in the home. The fact is, in my test of a Honda (H4) and Volvo (H7), I can say: 1. Standard Osram lamp / parking light / H4 / H7 enough to drive thus *** star 2. Osram Night Breaker H4 / H7 absolutely an increase therefore here **** star 3. Osram Cool Blue Intense / parking light / H4 / H7 can vote only with ********* Stars. When I read the crap here the Cool Blue is not at all blue, no it is not. There are possibly inserted in the Lamp shares the blue light spectrum. The Cole Blue Put together by other spectral colors. The spectral color is the pure light of a wavelength. The impression of white light is obtained from the mixture of pure light of different wavelengths. Using an optical prism or a fine grid, white light can be broken down into the individual wavelength components. Each wavelength component is then seen as pure light in the respective spectral color. Therefore, friends buy the blue light and none inside my tip is driving bus and train because you have no longer the problem.
