Had 4pcs 30Q discharge to 0v and left like that for 4 days, no hope whatsoever in reviving that low.
That’s quite possibly correct what Barkuti says but it’s a different story if a light has parasitic drain in an e-switch. That’s different altogether though, only a protected cell will stop that issue
0V for 4 days Sammie 30Qs? Well, you can make a test. Recharge them in some safe place to some not too high voltage, observe their self-discharge over a lenghty amount of time, even properly test their internal resistance. If cells still behave normally they could be used. But this is just because of “science”, in practical terms all of the involved effort is worth way more money than the price of a new pack.
I got the accessory sample for lighted switch ,
But there are two shortcomings, the tail is not waterproof, the flashlight loses its inverted function.
Wow, is there a chance to see the Convoys S11 and M3 with this emitter?
By the way, can you make a long back cover for the 21700 batteries for the Convoys S11? 26650 already withdraw from the market, to buy them all the more difficult and expensive.
Comparison of the S2+ KY CSLNM1.FY
All taken on my phone, with fixed white balance to daylight.
KY CSLNM1.FY (S2+) - note the broad spectrum has some colour rendering
SST-20 2700k (S2+) - high-CRI
XP-E2 Amber (KDLITKER E6) - monochromatic
Overall impressions of the S2+ with KY CSLNM1.FY - “beautiful” golden/orange beam, with some colour rendering. Warmer than the 2700k SST-20, but not as warm as the XP-E2 Amber. 5A driver is completely over the top for this emitter, and it gets too hot within a few minutes even on 35% output, thus I’ll need to use it on 10% or 20% for night photography. This emitter would better suit a 3 or 4*7135 S2+.
While I understand there are no 2700K SST-20 tests afaik, the 3000K and 4000K high-CRI tested emitters peaked at 6 and 7A respectively, both with quite high Vf at these currents. So, 5A can be considered fine. With a full battery or close you will be driving the 2700K SST-20 close to maximum performance, but as I say still fine. Concerning the temperature thing, it basically is the same with any other emitter. Tip: you can reduce the amount of dissipated heat by charging your batteries to a slightly lower voltage (3.9 - 4V). This also enhances their lifespan.
30% is 1.5A, should be fine. The drivers also feature temperature protection anyway. If I were to have it, I wouldn't complain at all. Just learn to use it wisely and properly, and enjoy.
The post was discussing the KY CSLNM1.FY. The mention of the SST-20 was just a comparison.
Also, for my photography, I need constant brightness as otherwise I would have to change the exposure for each photo, thus I need to brightness levels that won’t trigger the temperature control.
The CSLNM1.FY is a phosphor converted emitter, this means it must behave like the CSLNM1.TG standard white flat.
Now I understand your issue, the @#$% aggressive temperature protection. The solution is here: Convoy 17/22 mm SST40 Driver temperature protection removal. It involves removing the onboard surface mount NTC resistor. Once located, push it by one side with a hot soldering iron tip until it launches. Salute once done, LoL!
