Ah, although I prefer the more neutral tint of the PM1, I am impressed with the NM1 due to running at only 5A compared to 8A. Convoy’s 8A driver uses a timer instead of a thermal limit which can be a bit of an issue. I haven’t run a runtime test yet, but I expect it to get toasty. The NM1 on the 5A gets roughly 3 minutes before settling at 40% with still over 1000m.
The L21A gets a much, much longer run at the 5A though.
One slight concern is Convoy’s 5A driver seems to be running at 5.7A, instead of the rated 5A. The old version had a R1010 sense resistor and the new one has an R1020. I tried measuring amps at across the LED wires, but ended up shorting it out and frying the driver lol. I doubt it’ll be over 5A though, and if it is I think it’ll still be okay
How did you order the S16 with SFT40? I could not find any link in Simon‘s webshop. Is it a custom built version? I would be interested in buying it, too. :-)
May not be exactly related… But it seems there are sometimes slight changes in Convoy’s driver.
In particular, I’ve ordered the Convoy S2+ SST40 at different times.
The earliest S2+ SST40 (“5A driver”), I measure around 4.4A at max brightness (tailcap current, using UT210E ammeter)
(the driver-head spring is thinner and is spring-bypassed)
The next revision S2+ SST40 (still “5A driver”), I measure around 4.8A at max brightness
(the driver-head spring is more straight cylindrical shape, thicker than the first version, not spring-bypassed)
The latest S2+ SST40 (still called “5A driver”, I think), I’m measuring 5.2-5.3A at max brightness.
(the driver-head spring is sort of “trapezoidal” shape, similar thickness as the second version, not spring-bypassed)
Since I don’t have a light integrating device, I just use a lux meter and ceiling bounce in a small enclosed room to check the ceiling bounce lux. And the tailcap current does correlate to the lux. (All of these are the S2+ SST40 “4-mode” driver)
yup, that's the way it works with Simon, he's really good about it. When SFT40 is back I'll prob pickup that s16 or the m2, or maybe the m4. Thanks for sharing id30209
I have been very interest in Simon making a light like you explain there:
single 21700 host with head as big as L6 (or even a little larger) Honestly I would say make it a single 26650 with 21700 capability, so it looks more proportional. I like the "L21c" or even a "L6s" or "L7s" for "short". Oh, and of course for it to run the osram led's
It’s difficult to order this model. I’m considering getting GETIAN to produce similar LEDs.
The structure is the same, and I am asking about the parameters of the chip.
