Xenon HID upgrade bulbs are becoming increasingly popular with drivers seeking optimum performance and styling for their cars. OSRAM have developed Xenarc Cool Blue Intense, a range of xenon HID upgrade bulbs which offer a more distinctive and stylish look in comparison to standard xenon HID bulbs. The up to 6000K colour temperature delivers a crisp, ice white/blue light.

(Please note – due to xenon technology, HID bulbs will achieve their optimum Kelvin rating after a short amount of use. Please allow approximately 20 hours for them to reach their true colour.)

Great replacment


Bought to replace an old set of Philips HIDs in my Lexus GS350, good brightness- Not Incredible but noticeably brighter than the old ones also not really blue at all but a nice crisp white what is what I thaught they would be anyway. All up good for the price you pay

Excellent product!


Bought the OSRAM Xenarc Cool Blue Intense D4S Bulbs in October and had them fitted to my 2013 Lexus IS300h F-Sport last week. They look awesome on my vehicle and are a massive improvement on the weak and yellowish beam which the car had! Highly recommend this product as well as PowerBulbs who were very helpful when I contacted them for advice.

Good product. Quick service delivery to Australia. Product genuine.

No hint of Blue.


Vehicle tested: 2014 Lexus IS350 F SPORT AWD Bulb size: D4S Bulbs cast a pretty decent white light, but look like a 4500k or so. I have a set of Xenarc Originals and they look exactly the same. Despite the name saying "blue" there is not even the slightest hint of it. I suggest just buying the Originals, or if you want something higher than 5000k another brand. overall satisfied with PowerBulbs and unfortunately i will just stick with these bulbs due to costs. Side note, shipping to Canada is super fast (free option was about 5 business days)

Super quick delivery


just received in 6 days. Excellent product and lightning delivery. Bluish white at start up and then settle up around 4800k might need a break up time lets see.

Very slow shipping to US


Ordered the bulbs 2/22 and received on 3/8 (15days). If you're in US, recommended to buy express shipping at additional cost. Otherwise, the bulbs looks like Genuine.

Osram Xenarc CBI D4S


The lamps are much brighter than OME-Philips(4300k) with pure white color-5000k plus as advertised. Best price and fast delivery though more importantly it's authentic Osram product. Thanks Powerbulbs.

Super Bright/Lots of light output


2011 Lexus IS350 F Sport I was getting bored of the factory 4300K HIDs. Long story short, I bought from a different vendor, a pair of expensive 5000K HID bulbs. They turned out to be more of a 6000K compared to other 5000K. They wanted me to jump through hoops because they said their product are accurately rated at 5000K. Just say I will never buy from them ever again. Then I saw these, Osram Xenarc CBI. Powerbulbs.com always has the BEST price and BEST deals and superb customer service. As for these are bright, even brighter than the other car guys and their 35w/55w 5000K HIDs. I can see further ahead on the road, off to the side of the road. Just say I feel much safer driving at night with these amazing HIDs. I would highly recommend them to anyone. I would definitely buy them again.
