【convoy】H4 and B35AM options are updated

Hello everyone,

I’m buying my first true flashlight. The convoy S2+ is the obvious choice.
I’ve been studying, reading and comparing for some time, to decide on SST-40.

This was true, until I recently discovered Simon offers S2+ with LH351D with new 5AMP (non 7185) driver.
I checked specifications along with test here on BLF online - and it seems that 3AMP is maximum with LH351D, unless I want to risk my led to burn.

The question is - how does the 5AMP driver works with LH351D? Doesn’t it destroy the led? Is this driver safe with this led? Or do I need to set the 12group driver to e.g. 0.1% 1% 10% 50% and never put it on 100%?

Please can you explain?

It works fine. Search for ‘lh351d test’ within this forum. It can withstand way higher amperage than 3A.

Yeah, the only thing that I would consider limiting to 3A is Nichia emitters - E21A a lot less, but 219b is about 3A. LH351D, I’d throw 5A at it without blinking.

Last time I selected webmoney as a payment method, it sent me to webmoney website then I closed the page, the order was left ”unpaid” and I could ask Simon for blf discount/consolidate shipping costs

Nice to know workaround, thanks.

This is, what I’ve been refering to: Samsung LH351D 5000k LED output test by Texas_Ace

I’m confused now. Is there anything, that I’m missing here?

That test is what we have to refer to but I've been using a Convoy 4 mode, 6A driver in an S21A for a while and there's been no issue.

In fact, what I've seen in my SP32A, D80v2 and the S21A with a LH351D is no amp reading higher than 5.5A. So, I think that LED will be fine with a good thermal path.

Personally, I'd go with an SST40 unless the hi CRI is all out necessary.

Vietnamese FB group showed S21A colored...

Has anyone else had an issue with the Omten switches squeaking? I have a fairly new S6 and S2+, and both switches squeak on half presses? Anything I can do to quiet them down?

Squeeking on half press is normal because that operation last half a second usualy...

Squeeking while released is bad. Poor conductivity. That problem i have on M21C with xhp35 driver and high power emitter

:heart_eyes:

Sorry, it cannot be used.

It is available now, I will add a link as soon as possible.

the reflector of L21A lightweight version has the same style as C8 reflector , How about this?

Excuse me, do you mean that 2.5A red led driver cannot be used in a S2+ host? It is 17 mm wide, isn’t it? Will it fit into S3 host then? Because I need a small red light, and I have already ordered red osram on a 16 mm board.

Will there be a S2+ with KY CSLNM1.FY?

Waiting for Simon’s answer...Orange S2+ with yellow-orange Osram

And for this setup, a 6×7135 driver would be the best. S2+ body is small, so even 8×7135 is too much - considering, that this LED does not tolerate heat as much, as many others - so it either needs limited power or good heatsinking with a good amount of thermal surface.

Gents, you haven’t done your homeork...

KY CSLNM1.FY uses the same driver as RED Osram which means low Vf of 2.5V.

So my question still is: is 2.5V driver compatible with S2+?

I would be happy with a 4*7135. Really just want to be able to run it as bright as possible without getting too hot for around 10 minutes (for photography lighting).
