I am interested in 1 FW3T stonewashed
Possible interest. I personally like bead blasted titanium, what’s the difference between stonewashed and bead blasted finishes?
I want 1 FW3T stonewashed 100%! ( SST20 4000k) …
Yes, why ? I always thought the coolest running led was the XP-L…
In for 1, 100%!
I want 1 or maybe 2 FW3T stonewashed 100%
I am interested in one. I don’t have a titanium light.
Will buy one light 100% - SST20 4000K
Thanks!
I “may” be interested in one… but not sure. Maybe if I know the exact final prize
I am interested in 1 FW3T stonewashed SST20 OSRAM
Neal had written about the SST20 - maybe a missunderstanding
they will test the full Ti of course and maybe dactivate the FET if needed too

That should be great option for modders, 219B for example
The SST-20 5000k/6500k is the most efficient in a light like the FW3A.

Actually I think XPL HI is the most efficient (in terms of lumens per watt). It produces more lumens and less heat than even the cool white SST-20.
The cool white SST-20 is throwier though. In terms of lux per watt it might be more efficient.
No, it’s actually more efficient.
See the title, it is another test. do I really need to explain this everytime? I abuse an LED and see what it does, same as all the rest of my victims subjects. Thanks to CRX for donation. Well, you have seen the XP-L HD test, so here is the HI. It tracks exactly the same as expected, just less output from the lower bin. I could have kept pushing it harder but I saw no reason to blow it. The numbers could be a tad low in the high end as my heatsink fan is messed up and I had to rig something …
I got this emitter from Kaidomain on a 20 mm MCPCB. [image] Mounted on a CPU heatsink with a nice splash of thermal paste and over the top 16 AWG wires.

Exact order and bin code: SST-20-WCS-A120-L2651 VK BA Where SST-20=self explanatory W=white LED C=cool white S=CRI 70 A=solder pad configuration (3.25 x 3.25 mm) 120=viewing angle, 120° L2=flux bin rated at 85°C, 530-560 lm at 1500 mA VK=fo…
Up until 5A, the SST-20 is more efficient than the XP-L HI.
Is it possible to buy a non stonewashed FW3Ti?
Interested in one with HiCRI Samsung LH351D
No, it’s actually more efficient.
Luminus SST-20-W 6500 K CRI70 color and output test
Up until 5A, the SST-20 is more efficient than the XP-L HI.
Surprising result. I had a lot of respect for SST-20 and now I have even more.
Note that TA has tested V2 bin while the top one from Hank is V4 and normally V3.
Also, TA lumens may be significantly different from maukka ones, either higher or lower.
Assuming TA lm = maukka lm V4 would be more efficient in FW3T Turbo. But without this assumption it’s not so sure…
I think it would be interesting to compile some direct comparisons…
