Duffy, the one you linked to has 3x7135 driver... not bad, but the weakest of all Convoys.
If you insist on ordering from US, then get it from mtn electronics...http://www.mtnelectronics.com/index.php?route=product/product&path=80&product_id=582
This one is 6x7135, and you can choose your preferred tint color. I prefer 3B (neutral white) personally. In addition to tint color choice, they have other body colors available, too.
Also, these have the older XML2 LED which has a floody beam pattern, and old UI (2 groups only). If you prefer more of a hot spot/more throwy beam pattern then you want the XPL HI LED. There is also a new biscotti UI (12 modes) with many more different output options available if you order from Convoy China directly.
Ive got two S2+ lights... one has xml2, and the other has xpl hi led... they are quite different, so it really depends on what you want. The xml2 is nice for walking at night or for indoors to light up a wide area at a shorter distance. The xpl hi can reach a lot further due to a more pronounced hotspot. Both are very nice lights.
