【convoy】H4 and B35AM options are updated

Available now ,but there is only 4modes currently ,the 12groups driver is still in production

Hi Simon, T3 is still advertised as (pre sale) $999 listing. When will 4 mode T3 listing be advertised?

Also Simon, I would appreciate your opinion on Acupuncture?

Oh, stop needling him…

I’ll take another picture later and correct the price.

I’m confused. Are you asking me a medical question?

Not medical. Just your opinion on if you’ve had it done, or think it’s beneficial for ailments? Such as for Pain relief

Sorry, I don’t know anything about acupuncture.
I only experienced cupping cup and scrape therapy.

Have you thought about developing flashlights with dual diodes and dual batteries? For example 2*LH351D/2*14500 or 2*50XHP/2*21700 and many other options.
I have already seen many such inexpensive flashlights on Aliexpress, apparently there are factories that can make such cases from aluminum at an affordable cost.


Does L21B KW CSLNM1.TG come with a 5A 17mm 12 group driver?

I think I received one with a 6A 20mm 12 group driver.

Measured 6.5A on 100% which is a bit high for CSLNM1’s max 5A.

Hope you don’t mind, Tim, but that’s one of the best focused Osrams I’ve ever seen. Did it come from Simon that way, or did you adjust it?

It came focused like that from Convoy. I ordered the L21B KW CSLNM1.TG from Convoy store on AE a few weeks ago. :+1:

It looks like the beam throws further than my Manker MC13 White and it has a much more focused pencil beam.

I need to figure out how to use maukka calibration lights and a UNI-T 383S to measure how far it can throw. :person_facepalming:

You don’t need calibration lights to measure throw.

Just take a Lux reading from a measured distance, around 6-10m is usually good. Then enter your numbers into this - Lux to candela (cd) conversion calculator

Well, the below example is same light same distance, both lux meters are brand new. I have measured against the Extech another 6 light meters (less and more expensive) and all are measuring minimum 20% higher, nevertheless none of them measured as high as the Uni-T. And the funny thing is, that the laboratories I managed to find are proofing the lux meters, but only with standard light source (not LED) only up to 1000 lux, while the Ex-tech only has data for LED. Measuring lumens is easy with Maukka lights, but throw is confusing for me with such differences. Any ideas how can I narrow down the results?

:

I got the same L21B (CSLNM1.TG, 12-group driver) and the driver looks similar to the one in your picture.

Using UT210E clamp meter, and with a fully-charged 21700 battery, I measured up to 5.4Amps tailcap current (not 6 Amps).
I'm not sure if this is the 5Amp or 6Amp driver. The box label indicates "5A 12-group" though.

Beamshot of the Convoy L21B (Osram CSLNM1) (5 Amp driver? - although I measured around 5.4 Amps max tailcap current when using a full charge battery)

for reference, this is the how the scene looks during daytime

distance as measured by Google Maps

Thanks!

I measured this with my UNI-T 383S:
1488 x10 lux L21B CSLNM1 at 6m = 535680 cd
Throw: sqrt(535680 cd x 4) = 1463m

And Manker for reference;
4831 lux MC13 White at 6m = 173916 cd
Throw: sqrt(173916 cd x 4) = 834m

Distance and height could be off by +/- 10cm when placing the flashlight at one end of the room and taking the measurement. I used Max mode and moved the beam across the sensor.

The distance is critical and does vary the numbers quite a bit. I get 155,800cd from my MC13. So yours is either performing really well, or your numbers a little high (or mine low)

I’m using a Vapcell M11 18350 charged to 4.20V

I was holding the flashlight on top of two boxes. :person_facepalming:

Simon, can you tell us when the 12 mode driver will land for the T3… will be waiting for that one.

As far as I know, the Convoy L21, be it B or A, uses a ∅22mm driver. Then, the ∅22mm “SST40” drivers (12-groups, 2-modes, 4-modes) claim up to 6A of output current, i.e. they should limit current exactly to a maximum of 6A.

We already know there have been some shenanigans involving the aforementioned driver family. However, d_t_a claims that his L21B only goes up to 5.4A, which is abnormal to say the least… ¯\_(ツ)_/¯
