Simon, hope you did not order a large batch of the SST-20 FB4 tint bin. Once you get some Cree 5D tint emitters and compare it with the SST-20 FB4 tint bin, you will understand why the FB4 is not very good looking.
Until you shine on skin or wood etcetera…
That’s when CRI and R9 values come into play.

Dont worry ,friend,not everyone hates FB4,
and i will add FA1 or FA4 in my store ,i just supply one more choice for buyer

… I am worried that the copper surface is easily oxidized.
I see no problem with it, copper barely oxidizes at low temperatures. On the other hand, standard rosin flux comes in super handy to remove its oxidation while still hot when hot air soldering or reflowing, for example.

Great to hear Simon, definitely interested in FA1 or FA4 when it becomes available.
I dunno what CRI the XPL HI 5D's are, but wow, the more I look at them and compare to other LED's if one LED to one LED lights or triple to triple, everything else is blahhh. I assume they are in the 70's for CRI - not sure if anyone tested them, but Richard at MtnE and Hank at IOS don't list the CRI for them. XPL-HI's still seem pricey though, where others now are like 1/2 the price.
Almost all the available Cree 5D tint are 70 CRI. I wish they had some 90 CRI version. The E21A 4000k and 219b 4000k 9080 looks similar to Cree 5D tint but with better color rendering and lower output. I suspect the SST20 FA1 tint bin will look about the same as Cree 5A or 5D tint.
Simon any chance you will consider making the pills out of copper instead of brass for better heat sinking and heat transfer?
I am worried that the copper surface is easily oxidized.
Why worry about oxidation when it is not visible? It will not affect thermal performance. I bought a light from Enogear that had a copper pill. It has amazing thermal performance.
In this flashlight the copper has only thermal purpose. But in an S2+ the pill transfers current from body to driver. So oxidation is not good for electrical contacts.
With such a huge contact area, I doubt any oxidation will affect current. I have been using copper triple emitter pills in the S2+ for so long and measured no change in output.
… Why worry about oxidation when it is not visible? It will not affect thermal performance. I bought a light from Enogear that had a copper pill. It has amazing thermal performance.
Tactical forward switch?
Oxidation is not a problem and is anyway easily solved.
The actual problem for Simon Mao is probably finding a reliable source at a fair price for copper machined parts. We need to admit this may come at a premium pricetag, but it is doable.
Copper is mine! Copper divine!

I’m new to BLF, so I have some questions prior to ordering the S2+ SST20:
From reading posts, it looks like most everyone owns a S2 and if I’m correct its because Simon supports moding by making hosts, reflectors, drivers, etc available at Ali?
Can anyone explain the four color choices — 7135×3, 7153×4, 7135×6, 7135×8?
Is the head glued in finished S2+? I’d like to use this light to learn from, so I want to be able to easily open the head and look at how a driver is installed, etc.
How do I get the 15 percent discount, do I PM Simon here with my order number?
And, final question on a battery for this light, from reading other posts an unprotected NCR18650GA should work great for this light, thoughts?

Hi CMU_84!
Those are not “colour choices” but choices about the driver and the number of 7135 chips you can “have” on the driver. More chips mean more power, more output on top levels (100%), but also more more heat when using the flashlight for longer times.

The head is not glued. Depending on the number of 7135 chips you want in your flashlight’s driver, the driver may be soldered to the pill (6 or 8*7135) or it may be held with a retaining ring (4*7135). So, you can unscrew the pill and de-solder the driver or simply unscrew it to access the driver and start modding

Yes, but you also have others with high capacity, such as Samsung 35E, Sanyo NCR18650GA .

I would buy a new piil, driver, led and led plate for any modding I would do, but I would like to be able to open the pill that comes with the S2+, so that I could examine and learn. And, I would like to retain the shipped pill, so that I could use the light i.e. no de-soldering.
I know this may be a question for Simon, but replies are welcome from all members, what is the largest number of 7135 chips I could order on the driver and the driver is held by a retaining ring?
I do not think that a copper pill will do much over the current brass pill at the 3A max current that the S2+ comes with. And it is more expensive to produce. Providing a copper pill will mainly cater tbe BLF modders that overdrive the S2+.

Thanks for offering the new emitter options. The S2+ was always a good budget light, but XM-L2s aren’t exactly pretty. I maintain a popular recommendation list and I was happy to be able to add the S2+/SST-20.
FA1/4 bins for the SST-20 would be most welcome. I’ve been using FB4 from Kaidomain, and the tint is OK, but could be improved. I can add to what others have said about the 219C as well: it’s fine at 2.8A. It’s fine much higher than that, actually and can take more current without failing than the SST-20 can. (7A is fatal to an SST-20.)
I’d really like to see an official listing for the C8+ with the SST-20 and 7135×8 driver. I know it’s possible to custom order it that way, but I want to add it to my list, and it’s much easier to provide a direct link than explain a custom ordering process.
