H7 is halogen, as far as light output of halogen, people rave about Osram Nightbreaker series; but you can only get them from UK/overseas (check eBay for seller). I am ordering fog version H3 from UK seller (4-8 days shiiping) to see if all the hoopla is true.

Sorry, didn't realize you are looking for HID, yesy D2S for projector style headlamps or D2R for regular reflector style.
