I would not get them just because the temperature rating is wrong. The hotest HIDs you can get right now are 6000K, I think, and those are made by a reputable company, Philips.
Think physics...there is no way 55w=100w unless it is indeed 100w. If PIAA has managed to increase power output with 1/2 the power input then this is revolutionary for the planets energy needs.
Anything over 5,800k will reduce vision in HID systems. The Philips Ultinon is indeed 5,800k but marketed as '6,000k cool power xenon.'
