All, whitewall shots now added.

Thx fernandoz!

@357mag1 - unfortunately my raw files got corrupted so I'm working on recovering the data but basically, given all that resistance introduced with my setup, the S1 never ran in regulation. According to XTAR, the S1 will fall out of regulation at 3.2v, I do recall that when I started the test, it was already at 3.6V and falling and again, never did run in regulation. If I manage to receover the data, I'll post the graph.

Cheers,
Tim

Comparable (@75m which I tested) but different beam profile. The S1 has a very broad hotspot whereas the TN31's is very tight. I posted a vid in the TN31 review but you can watch it here (they are the first two lights up):

If you want a light that will WOW them even before you turn it on this is the one. Even when off people just look at it and wonder :eek:
