Does it mean that the S21d running the 12A driver will be hotter than the 8A previously?
When do we expect the 8A buck driver to be in stock?
Agreed, xhp50.3 HI would be a great choice, especially if some warmer color temps will be available.
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.
17mm 6V 4A 12group could be set to 50% group and used with B35? Or make a 3A version?
If you need a 17mm B35AM driver, I can produce a 17mm 6V 2.2A dedicated driver.
It is more dangerous to use a 4A drive.
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?
yes, thread is suitable ,but the S3 is a little blunish ,the S2+ 18350 tube is a little greenish
Simon Mao: lg.tech:@Simon, any idea when the SFT40 5000-5700K and the new 17mm 6V boost driver will be available?
LUMINUS may not produce 5000-5700k sft40,
I got 17mm 6V 4A driver sample , But I’m not sure which LED to apply it to, what about XHP50.3 HI ?I think XHP50.3-HI is an excellent choice. Will you stock it in multiple CCT’s? I would love to install it in a C8+ in 4000K.
I don’t know why XHP50.3 XHP70.3 has been on the market for so long, but we can only buy white light.
Does it mean that the S21d running the 12A driver will be hotter than the 8A previously?
no ,Affected by voltage and internal resistance, as well as temperature control, the current actually drops very quickly.
When do we expect the 8A buck driver to be in stock?
About one month ,and new version has spring.

Thickness 15-25 microns, hardness about HV400

I’d be interested in lights with 90 cri versions, if available.

Those look like numbers for type III hard anodizing instead of the MAO. Is that correct? I guess the thickness can vary but looks like the standard is from 25 up to 150. HV seems to be 600 on the low end up to around 1400.
thefreeman: Haukkeli:I also like S3 more. To my eye it seems to have even little bit better quality than S2+. Sad there’s only two colors available.
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).
The S2+/S21A is nicer to mod due to the pill design which can be screwed in a bit more or less when you modify the reflector
When I need try different Tir lenses I prefer have host with unscrewable head and integrated shelf similar T2 design.
(I would like if the mcpcb where even more raised to facilitate Led slicing)
The advantages are quick easy Tir Lens change, Led access and more space for larger drivers
than host pill based like S2+ where are necessary more operations and time.
Simon there will be a T2 style light 18650/350 compatible with threads and TIR lens used on S2+?
I don’t consider S3 for their recessed Led inside the head,a bit difficult for modding
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.
Sorry, don’t understand this point. So, currently, Aliexpress has only 12FET+… options available. You say you’re not gonna sell 12FET, so, what does this option actually means then? 8A FET? 8A CC?

I believe another user was asking to buy the parts separately instead of the whole complete light

Awesome, I’m not really so worried about matching colors, I can actually just use a different color for the 18350 tube.

i mean ,i can install 12A fet driver in flashlights ,but i am not allowed to sell the driver seperately
lordlupulin:17mm 6V 4A 12group could be set to 50% group and used with B35? Or make a 3A version?
If you need a 17mm B35AM driver, I can produce a 17mm 6V 2.2A dedicated driver.
It is more dangerous to use a 4A drive.
Yes Please!!!

no ,Affected by voltage and internal resistance, as well as temperature control, the current actually drops very quickly.
Is 8A buck and 12A linear? So 8A more efficiency?

Lot of people would be interesting in this.
Is it possible to use the same 17mm driver but adapt it for 3V and 12V as well?
