Osram Silverstar is a great choice (not the Sylvania Silverstar).
Sounds great and thanks for the link - according to Daniel Sterns Lighting, there is functionally no difference between the endorsed brands (see * quote below) It also seems you can call them and order a lamp which I plan on doing tomorrow. Thanks gain 2cati for the help - love the scientific approach to things - especially when it comes to lighting (I have a photographic background)
*- About H4 +50 Bulb Brands:
The H4 +50 bulbs from the big four reputable European bulb makers (Philips VisionPlus, Osram SilverStar, Narva RangePower+50, Tungsram Megalicht) are functionally identical. When we pick ten samples of each and put each one through photometric, optical comparator and life tests, there's a very narrow range of performance and life differences, and those differences are randomized among the four brands.
