OSRAM XENARC COOL BLUE INTENSE D1S, +150% more brightness, up to 6,200K, xenon headlight lamp, LED look, duo box (2 lamps), 66140CBN-HCB

When you first install them yes they do look yellow (as many people have commented), but they improve significantly after 15-20 hours of use. Sadly Osram do not state this on the packaging as far as I can see so the confusion isn’t surprising. I’d say they’re a definite improvement on the first generation and would recommend them, you just need to give them time to burn in.

Very easy to install and good brightness. However, not noticeably brighter (or more blue) than BMW F32 M Sport OEM bulbs. In any event - perfectly decent bulbs, brightness and colour.

Replaced my 6year old osram original bulbs with the cool blue intense gen 2 and difference was immediately obvious. So much easier to drive at night now. As you can see the light is quite noticably blue, it just needs to be run in for a few hours to reach the final colour. Note - Amazon says its not compatible with 520D F10, however it is. Great upgrade.

Very bright bulbs, great replacement value for my oem bulbs giving a premium look

Do the job but not as bright as expected

T Those bulbs make significant difference, Highly recommended to anyone, all bulbs burn out and loose brightness,, when u change in those u will notice difference, just don’t touch the bulb while fitting, get mechanic to fit them u will notice this time of year when it’s day getting dark sooner

Bought this next generation to replace my old bulb which is the first generation. The second gen should be better than the first gen in terms of colour temperature and brightness. However, it is very disappointing to see than gen 2 is even more yellow compared to gen 1 (see attached). It claims gen 2 should have 6200k but when comparing with my gen 1 bulb which should be around 6000k, it is very yellow. I am also not convinced by “150%” brightness shown on the box as it is more or less same as my old gen 1 bulb. Very disappointing as all my cars use Osram but this new one doesn’t perform what it says on the tin.

Working fine

Se ven en color cálido, espero que con el uso alcancen los 6200k que indica la caja, llegaron antes de lo previsto en la app. En comparación con la iluminación que traía el auto con los xenon originales mejoro la iluminación, adjunto el antes y después. Instalados en Ibiza FR 2015

اصلي كما في الوصف أنا راضي وراح اطلب مره أخرى لسيارتي الثانيه

Great bulbs. The brightest DOT/ECE-compliant xenon bulbs available, as far as I'm aware. Crisp white output.

Rendu confirme et qualité Osram

Las compré tras fundirse la original ya que era la que llevaba. Da una luz muy muy buena, tras unos años parece que ha perdido algo de potencia pero nada significativo. La calidad y consistencia de la luz son muy buenas. Bajo mi punto de vista un poco mas blanca la luz estaría mejor.
