Thanx for the info.
Glad to see interest in this emitter.
I've still been wrapped up making mistakes with less expensive leds and haven't touched the -50 since that post. But what did I buy an evaluation led for but to mess around with?

I fried my xp-e 7C last weekend :-( Don't think I want to risk frying one of these :sigh:

Hello everybody, I was thinking in buy some of this Leds, the question is;
Wich one to buy?
Bin Code
Color
Vf
Lumens
Wich one is better to make mods? With star or without star?
I think the 5700K option will be a good choice...
I am looking for the brighter one, but I dont know about the bin codes.
Help please...

Well I have great news: there aren't any bins to choose from! You've already decided to try the -50, so chose emitter or star and you're set.
Yup, Photon Fanatic has some in the market place for ya, order tonight and you might get them on Friday.

Owing to more recent posts in this thread, and the imminent arrival of a high-output driver (details to follow if things work out), I put my plans on hold and tried out the ssr-50.
I had a hard time deciding between bicycle light and hand torch. In the mail today I recieved a blank DX p60 drop-in, and found my ssr-50 star didn't fit. Bike it was.
I'd prepared a heatsink with wire attachments some time ago, and artic epoxied the emitter in place. I had a set of all-weather wire connectors with a 15amp inline switch set aside for the -90 but used tonight instead. The wire, nice thick copper strands, is oversized for the little ssr-50 star.
1) These things are SOB's to solder. I am so very glad of all the practice I'd been getting. Perhaps it was an error to attach the heat-sink first, I could put the tinned tip on the solder pad and it wouldn't even flash-boil the rosen. I had to turn my iron up 50 degrees just to tin the contact pad (I wanted to build it up a bit owing to oversized wiring). The thermal clearing ability of the luminus heat speader is very evident, it's far beyond the cree, seoul, and lux boards I've used. I totally understand the problems Nailbender was writing about now. I'm glad I didn't try doing this before.
All set up, flick the switch, nothing.😕
Seriously, WTF?
Trouble shooting complete, the wet connect has an end reversed. The black wire at the battery ends as the red wire at the led, the black wire at the led ends as the red wire at the battery. I'm considering sending it back and asking for contribution to reverse polaritied ssr-50, but now that I've got it installed, is it worth it?
Interesting point from this though, the -50 still works. It took a full direct drive hit from an AW IMR 18650 (and 4s Eneloop during trouble shooting) with the wires crossed, no apparent ill effects. Again, glad it's an 'evaluation' piece.
When I did get it going, lovecpf
Wow. It lights up my back-yard and this is only DD off a single AM IMR 18650. Going to compare it to an Auraura AK P7 DD solarforce 18650 right now when I take out the garbage.
Pics tomorrow night if I'm lucky.

Some measurements from last nights demo.
Dm measures aw IMR 18650 at 3.95v (no load) before the ssr-50 subject to reverse polarity, no visible effect (damaging or otherwise)
After moderate use, imr (no load) 3.81, under load voltage at the emitter leads ranging between 3.28 - 3.32 (direct drive).
After taking out the garbage (maybe 10 minutes of use), voltage at the emitter again ~3.2X (load), up disassembly IMR reads 3.76v (no load).
Took a few quick pics when I got home from work today, uploading them now I see unfortunately the setting sun messed the lighting.
The cover is off so that emitter is visible, and I've run the wiring around to get the in-line switch in the pic.

FYI, avnet is showing the GH102 in stock. It's not the GJ, but a big step up from GF.
Their website is a bit squirrelly, so here is a direct link
SST-50-W65S-F21-GH102
https://avnetexpress.avnet.com/store/em/EMController/_/A-9026214/An-0?action=part
I bought two for no damn good reason. Will probably just resell them if they show up.

Thanks for the announcement. I got the two right after you as it said 18 available when I ordered. Strangely enough I got an email saying my order had shipped the same day but at 1:30am. They sure do work late there.

I took a long shot and also ordered a premium bin (gh) high cri (83) warm tint (3000k) along with the bin you'd linked. Previous posts said avenet contacted them with alternatives, I'll see what happens.
Luminus lists up to 93 cri, with very comperable output at the highest flux bins. Now it may be a year before these emerge, if ever, when they do a high cri neutral (4000k) tint could make an excellent replacement for my dive light.

I did promise these beamshots a while back, but it's been a challenge (to say the least) to get the emitter mounted and the DC-DC driver sourced and tested. The copper bar was special order, the machining was custom, the DC-DC converter was special order - and the first one was defective - had to reorder....
[Thanks to Troutie, who made this all possible by machining the copper heatsink for the 2C Mag].
The beamshots were taken using the flashlights and reflectors pictured below:
The SST-50 was run at 5A in each of the various reflectors:
Distance to the plant and hotspot in the pictures is about 10m. The camera settings indicated were chosen so the pictures would look the way my eyes see everything.
If you would like to know more about the 10A DC-DC buck converter used to power the LED, look here: http://www.candlepowerforums.com/vb/showthread.php?p=3089789#post3089789

:twothumbs Phew it all fit together I was wondering when the light would be up and working .
Looks good how hot does it get and how quick .

Yes, it gets hot. Especially if you don't hold it while it's running.
BTW, further to some extended runtime tests that I've done, I'm no longer going to use voltage regulation due to the neg temp coeff of the LED. I'll be using some Shark Bucks instead.
Also done some more beamshots and ceiling bounce tests.
The Tri Seoul P4 came in at 71 Lux, and the SST-50 produced 115 Lux (62% increase). Remember, the absolute readings mean nothing here, it's the difference we're looking for. I used a meterman LM631 for the test.
At 6A I got 122 Lux (72% increase on the P4's and a 6% increase on the 5A reading - or to look at it another way, 6% increase for another 20% increase in electrical power....still want to overdrive these?)
Distance to the Tree is about 25m. Tri P4 @ 980 mA first, the the SST-50 @ 5A.
The SST-50 does look brighter to the eye. I think it's a combination of higher colour temp, and more side spill.

Has the SST-50 been tested with McR reflectors yet?
McR-20, McXR17, McXR19... Anyone? Do they need modification?

I've not tried any Mcr reflectors, but I have tried an IMS 20mm from the shoppe. Loads of artefacts. There was a hot spot, but it was not well defined.
Something else I noticed. Quite a bit of light was escaping from the bottom of the reflector. I've only been using reflectors that have been designed for MCE's (& Crees ?)till now. I've noticed that the hole in the reflector is just big enough to fit over the clear dome of the SST-50. A fair amount of the led light is probably wasted this way because the LED sends out light from the very edge of the dome (see luminous intensity distribution on the spec sheet). You've then got the thickness of the reflector bottom before the clear dome part makes it into the actual reflector.
If people want to get the very most out of this LED, I think the opening of std MCE reflectors is going to have to be expanded to let the LED sit slightly higher.

Has someone married a pwm controller to this led? It would be cool to see how low current you could get and still have the ability to blind the wife for a good period to make your get away, once she found the receipt.
