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

After 12 years on the original OSRAM Xenarc D1S bulbs, the Night Breakers were a welcome upgrade. HID bulbs do change colour and get dimmer over time, and it is recommended that these types of bulbs are changed every 3-5 years. So when I did get around the changing the bulbs I noticed that they were significantly brighter than the original bulbs and the colour shift meant I could see more detail on the road too. I should have upgraded sooner. I was able to check the serial numbers on the OSRAM website to verify they were genuine bulbs.

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.

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

I use fro my Audi TTS from 2008, works perfectly, so far so good 😊

Decent replacement bulbs, similar colour temperature to the OEM bi-xenon bulbs fit to my old Audi. It was an absolute mission to fit them in this particular car but that is no reflection on the product itself. Given how difficult it is to access the light cluster to fit them, it’s definitely worth replacing the pair at the same time; if one has gone then the other one is likely to be near the end of its life too. These are pricey bulbs, but again, you don’t want to be repeating the job, so knowing the brand and seeing the decent light output, it’s worth the money, but this is ultimately why I took one star off the review.

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.

These were so bad, not blue as advertised but yellow and damaged my cars lens. After I realized that brightness was poor and the yellow color instead of blue. I decided to give em another chance thought maybe it needs time but the bulbs damaged the lens and bulb compartment and melted down the plastic. Do not buy

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.

Arrived sooner than expected. Great price. Good bulbs to replace existing ones

Improved the light output to my Aston Martin Vantage

OSRAM XENARC NIGHT BREAKER LASER D1S acheté en "occasion"; en pratique scellés cassés. J'avais des doutes sur l’authenticité (de la version night breaker laser) avec un premier test de jour. En photographiant l'autocollant arrière (photo 1), on voit que ce n est pas la même référence et on peut deviner avec les lettres que c'est la bonne version 66140XNN; à côté les bi-xenon d'origine sur ma Mini 2013. Le test photo 2 croisement, et photo 3 croisement + route lèvent le doute et montre le bel éclairage: plus lumineux 3200 lm, même forme de faisceau (est il plus long ?), peut être un rien plus blanc (4500 K T° couleur). Sur Mini, les croisement ont des optiques lenticulaires. L'idéal serait d'avoir les feux routes en bleu car cela fait scintiller les panneaux, en feu de croisement, c'est plus éblouissant. C'est ce que j'ai installé sur ma vieille Corolla, 2 Xenon avec températures de couleur différentes. Sur la Mini, le changement est facile (gants recommandés) 1- retirer le cache (un seul clip en haut) 2- tourner légèrement le boîtier métallique (de 12h à 11h vu de l'arrière) 3- retirer délicatement l'ampoule en évitant tout contact avec en particulier le phare 4- débrancher le connecteur métallique (pas de clip) stocker l'ancienne ampoule (réserve) 5- rebrancher le connecteur 6- replacer délicatement l'ampoule (il y a suffisamment de place pour que ce soit facile) 7- s'assurer du positionnement correct (repère 11h) et tourner jusque 12h on sent bien le verrouillage 8- remettre les caches (attention au positionnement des joints) 9- vérifier la hauteur du flux de lumière sur mur, porte garage etc 10- essai routier Je ne peux parler de la longévité à ce stade. Pour info: on peut sur le site OSRAM (trust package) vérifier les matching number (package avec le code à 7 caractères sur le boîtier et le SN de chaque ampoule) photo 4 & 5; ce sont bien des originales !

Ordered new Osram globes. Received used Philips globes. Disappointed.

Passen, leuchten, sind hell und halten. Super Upgrade zu Standard-Leuchtmitteln
