I was having a hell of a time matching the Kelvin between my oem headlight and aftermarket mini H3C
HID bulbs, so I decided to sell a little blood, and buy some Philips Ultinons. OK, I had to sell most of
my blood.
Ultinons are pretty much the Rolls Royce of HID bulbs. I picked up a set of D1S and rebased H3 Ultinons...
both in 6000k. The output on these bulbs is whiter with a slight hint of blue. OEM HID bulbs have more
yellow in them. Moreso, the drop in lumens on these Ultinons is negligible compared to OEM bulbs.
I fired them up earlier today, and the fogs seem to have 95% the color produced by the main headlights
(the Philips dealer told me there would be a slight variance based on the ballasts/ and projector optics.
Anyways here's some pics of the bulbs. I'll get some wall / night shots this week.
