Gentlemen,
The SSC Z7 has been out a few months now, but not a lot of info is available on them as of yet. To the rescue comes "Crystal" from LightCastle.com who sent me two bare emitters for testing/torture. I must apologize here for the procrastination, for they did arrive a few days before Christmas, but having taken a small sabbatical from the forums here lately, I'm only getting around to posting the info now.
Here you can see the new SSC Z7 on the right, along side an old xre q5 on the left. I wanted to run the test with the emitter mounted on a star to show real world results more closely (although this emitter is begging for a copper mount). Thankfully the pad dimensions are similar enough to the xre that I was able to re-use one of those.
Notice that the SSC on the right does allow for individual addressing of each of the 4 emitters, much like the cree MC-E and P7.
A quick reflow later, we're in business and the testing starts. Something I'm going to start doing with all my tests now is graphing vf at the various levels, which I at least find to be good info especially in DD applications.
Here's the two graphs:
Comparing it to the cree XML-T6, we see that it is a bit more efficient across the board, not to mention outstanding low current output. The SSC Z7 is putting out just over 250L at 600ma. I'm just speculating, but I think this emitter may find a niche in floody 1xAA headlights and small primary flashlights.
As of yet, I cannot comment on tint or beam pattern, because I haven't installed it into a light. I'll update here with thoughts/pics when I do.
As always, thanks for reading,

p.s. - One of these days I will get around to making one HUGE graph and table showing all the emitters I've tested thus far....should make it easier to compare directly one to another without swapping tabs.
p.p.s - Be sure to tell Crystal "thanks" for donating the emitters for testing!
. Those results are in the previous thread.
