Hi I am looking at replaceing my D1S HID Xenon bulbs, insurance job! What is the bluest bulb you have as my other bulbs were very blue and aftermarket bulbs. This is going into a 135iBMW?
The highest temperature bulb we offer is up to 7000K; Osram Cool Blue Boost, which is identica to CBA.
It's not necessarily blue but strong white with a bit of blueish hue effect. If you want significantly blue, you might want to look for 8000K or even higher, which we do not recommend using for safety concern.

Really nice white color.
I'm not too far from HID Concept, and called and picked up a pair of Osram Cool Blue Advance. I actually was just going to buy OEM D1S, but at their warehouse, the guy put the OEM bulb against the CBA, and I was sold on CBA's color. Definitely whiter than the OEM bulb and has a brighter hotspot. Spent a bit more than I was going to, but worth the money.
Very nice white lights. Glad I got Osram cool blue advance
I purchased Osram Cool Blue Advance D1S for my Audi from HID Concept and am pretty satisfied with the light output. Excellent price too.
Excellent white color and nice and bright. Fits nicely for my 2007 Cadillac Escalade
I love Osram Cool Blue Advance color. Nice and crisp white color. The only thing I regret is that free shipping was US post office and not as fast as I wanted to get the products. Next time, I'm going UPS
Just got my hands on Osram Cool Blue Advance. I was going to get Cool Blue Hyper, but Mike at HID CONCEPT told me about this new bulbs. The light output is tremendous. Love it!
