【convoy】H4 and B35AM options are updated

I'll post some graphs when mine arrives in a couple of weeks. I generally do runtime graphs on ALL my new lights.

Don't think I've seen Simon list runtimes.

Do we know beam intensity (cd) for S21A yet?

Description of S11 XHP50.2 states “maximum output 3A” and yet it delivers 2400 lumen? Is this correct??

Yep - should be on the money. 6V @ 3A, 18W…

The S21A days max is 6amps, yet the output is slightly less?

SST40, 3V @ 6A. 18W also.

Does this mean the s11 is twice as efficient for 2x the battery life if it runs at half the amps?

It’s the same wattage though - the XHP50.2 is a 6V emitter, so it’ll have a boost driver. Unsure how that affects the efficiency, but the S11 also uses a 26650, so longer runtimes.

Oh… ok. I guess my question is how many Amps does it draw from a cell? About 5-6A?

My (semi-educated) guess is about that, yep. 18w/4.2v = 4.28, throw in some inefficiency, that’ll be ~5-6.

How many amps does the S21A draw since it says 6amps on the website?

Most emitters will go above 3V at 6A, but still, a 10A battery will well and truly be sufficient.

Sorry, I’ll start again. Some other data I’ve come across since.

An XHP50.2 at 3A will have a voltage of around 6.2V, giving 18.6W.
An SST40 at 6A will have a voltage of around 3.4V, giving 20.4W.

If you go by a full battery, then 4.2V:

  • XHP50.2 is pulling 4.42A (without efficiency drops)
  • SST40 is pulling 4.85A (without efficiency drops)

If by a “half empty” battery, then 3.7V (assuming it can maintain full draw, which is more of a buck booster thing):

  • XHP50.2 is pulling 5.02A (without efficiency drops)
  • SST40 is pulling 5.51A (without efficiency drops).

Again - 10A batteries will do this well and truly.

guys ,who can do me a favor?
i want to know the correct diameter of sofirn soshine LISHEN vapcell 21700
I originally planned to buy these batteries directly in China. What I am depressed is that these Chinese-made batteries are not available in China or very expensive.

Really awkward :person_facepalming:

Which Vapcell? There are many. HKJ has all that info on his website.

very helpful ,thanks so much
max 21.7mm

Sofirn 21700 4000mAh 40A that came in Sofirn C8F (bought on last 11.11): 21.6mm (measured at this time)

ok ,thank you :+1:

Yeah, do a 23-click to restore the previous configuration. :person_facepalming:

soshine imr21700 4000mAh

w: 21.5mm
h: 71.0mm

On a side note: Sofirn's new SD05 diving flashlight has an inner diameter of 21.9mm, so it might accept even too big cells like Molicel M50A and Lishen LR2170SC.
