I wonder why it hasn’t replaced the S2+, isn’t a shelf design much better than a pill ? Better thermal conduction to the body, lighter, no brass pill to manufacture (lower cost ?), and with only one retaining ring (no pill retaining ring) there would be no need for reduced driver diameter, so it could be 21mm instead of 17mm, which would simplify greatly the development of a boost driver. Unfortunately it’s still reduced on the S3 (17mm).
It also makes trying different leds and optics easier. S21B has 22mm driver, when S21A has 20mm. At least in that model you can see the benefits of that construction.
i can send some TIR lenses to your for free, just note this in the remarks.
About the 12A FET driver, The manufacturer didn’t want me to sell this driver. You can consider the new version of 8A 12 groups driver.
Too bad about Luminus not producing the SFT40 in lower CCT’s.
As for the 17mm 6V 4A driver (12 modes). The XHP 50.3 HI is exactly what I intend to use, in 5000K with OP reflector. Essentially, that’s my build plan for my upcoming S2+ MAO or Ti in 18350! If I could get that already built by you that would be supper! :sunglasses:
I just looked at the S3 and noticed the new batch also has rectangular threads… Simon, can we use the 18350 rectangular thread tubes from the S2+ with the new batch S3?
Simon, do you know what the coating thickness is on the MAO finish for your lights?
Also, have you noticed or tested thermal performance with the MAO? I’m reading that it can drastically lower thermal conductivity compared to anodizing depending on the thickness and the type of alloy. Of course it’s on the outside from where the heat is generated but just curious.
