Here's some more info to confuse you!
D2S is always better to go with than H1. H1 is an aftermarket invention more or less and D2S is an OEM equipment bulb. The advantages of the D2S are insane. Widely available OEM ballasts and bulbs much better than Morimoto, although morimoto are very good, top of the line aftermarket equipment. IMO the 3" D2S also takes up the space of our headlight much better, the mini H1's tend to have smaller shrouds and look like of like chameleon eyes to me...
This is a killer chart made by a prolific retrofitter, Cesar of Lightworkz Global. His company is one of the best if not the best on the market and he's known for giving dubious amounts of advice and information out for free to anyone who asks even if it's not in his best business interest. This details the different projectors at the bottom, and well as different bulb and blast combinations, this is about as scientific as someone can get with this kind of testing and he is as mentioned a very trustworthy source and has no conflict of interest with regards to the sales of any of the products (he only installs).
