Thanks to the existence of “XHP70 drivers” it is possible to get some stock drivers configured for up to 4.8 - 5A driving current in ∅22mm size. User Windforce did some testing over a Manta Ray XHP70 driver bought from AliExpress, see Testing boost drivers' thread.
Of course ;-) I found rock-bottom price seller for the Manta Ray XHP50/XHP70 drivers:
djozz thanks for the testing. Since the die is closer in size to XHP-35, it would be nice to see testing at 12V, with a chart comparing XHP-50.2 also at 12V, and XHP-35, which is only available in 12V. That way, we could see where the SST-70 really falls between those two regarding output, voltage, and current. Is there any chance of that happening?
No
I do not have enough energy/time/dedication etc. to do all that. Even if I would promise it I will probably keep doing fun stuff first and this will end up nowhere (I have broken a few promises in the past, could not get myself doing it).
We need a HKJ of led testing for that, who is never tired of doing vast amounts of tests. Me I just pick out a promising led every now and then.
Well, thanks for taking the time to give an honest and respectful answer. And thanks again for the testing you’ve already done, both on this and other LEDs.
I would love such a never-tired led tester on BLF who has all the fancy equipment and produces new led-tests weekly of every led that hits the market. We are really blessed with HKJ, who is around this forum for longer than I and has done soooo much work over the years.
I did a fraction of what djozz and maukka do for some LH351D LEDs and could barely bring myself to do it. It’s so tedious but it really is helpful and referenced for years
A curio of this emitter: all dies are unequal. Upper and lower dies are different, being each side a mirror reflection of the other. Comparatively the XHP50A die is composed of 4 equal (XP-G2?) dies laid each at a different cardinal angle: 0°, 90°, 180°, 270°.
I didn't mean it to be interpreted that way Agro, so I edited my post. Each side is a mirror reflection of the other, plus above and below are different.
A unique footprint which allows to know at which angle of rotation is the emitter when zoomed in an aspheric build. O:)
I removed “early” from the title and the OP because with a flashlight mod already shown and KD having stock, the SST-70 seems so much around that I guess that I tested a normal production sample.
