【convoy】H4 and B35AM options are updated

The inner diameter is now 22mm
the thickness of the walls is 2.3mm

i have few 3V XHP50.2 LED in stock ,
I can also install XHP50.2 as you require.
It’s just that I personally don’t like the uneven light spot of XHP50.2.

The inner diameter is now 22mm

There are many other COB manufacturers that are just as good but cheaper, such as Samsung and Citizen. There are super cheap Getian Opto-Electronics, but less efficient ones. I made a lamp on Citizen CLU048-1212 80CRI 3500k Verison 6 I really liked the light.

In my experience XHP50 is more effective than SST40 and even 3 * XPL. Heats up weaker.

I also prefer the XHP50.2 over the SST40 for output and efficiency. One note though XHP50.2 must be at or below 5700K to reduce that yellow and green color aura. 5000K seems to be the sweet spot with an OP reflector with output about 20% greater than the SST40. If it’s only for throw then the SST40 all the way.

I need a 1500 meters thrower, 4500lm, 3000k, ramping, ipx7/5, usb-c and temp regulation with highest possible sustained lm. 1x21700 or 2x21700. Can pay 120 usd incl. shipping.



You can post WTB...

I have a 5000k xhp50.2 i grabbed from Kaidomain back in 2019 before they sold out and had it in my zoomie for a while before I swapped it into a C8 on a fet driver. I since took it out and it’s now in my parts bin. The Corona is less than the 6500k version, but still there. the tint is better. No way to know when it will be back in stock. I guess it’s going into a lot of industrial products and not many for the general consumer market? Supply/demand maybe. Tyne xhp50.2 is a pretty special emitter though. Besides the sbt90.2 no other 3v emitter can beat it for output without being driven ro death.

Would like to see a dedomed XHP 50.2 3000k-5700k in a thrower, how long it throws compared to SST-40 and NM.1.

The NM1 will outthrow it by far.

Well, I've always been interested in sunlight or blackbody radiator spectrum leds, and leds with those characteristics can be found. I have Guangzhou Juhong Optoelectronics in my favorite stores list for this precise reason (I straight linked to the Plant grow led module -> Sunlight spectrum led).

Take a look at this 10W 1700K CoB:

Driving these leds from li-ion cells requires special boost drivers. The Vf is quite high, consequence of their multiple dies in series arrangement. According to the specified Vf the one above must be 10 or 12S.

I have a 4x LH351B 3000K CRI90 custom made bedroom lamp, and definitively I find it too high CCT for a bedroom lamp. Of course, for comparison purposes I am also using a 25W e14 incandescent bulb powered lamp. I still have a bunch of these old school bulbs, they're a tad dim but quite nice. Their CCT is noticeably warmer than 3000K.

I think XHP35 HI and SST-40 have equal throw. XHP35 gives you more tint options.
I consider to buy Convoy L21A XHP35 4000K over the SST40 5000K version.

Or I will wait for a CSLNM1 with warmer tint.

The xhp35 hi has more tint options. Hard to say whether it will out throw the sst40. It has no dome and pretty high surface luminance. It will make slightly less lumens than a well driven and cooled sst40. The downside is the xhp needs 12v and is only driven to around 2.5A max.

I agree , Anduril & USB-C :+1:

imho : It will be great if convoy make flashlights with Anduril. Maybe even better with Anduril-2 , it seems to have a very useful & practical Simple UI , more solid than “muggle mode” of Anduril-1 , that’s from what I read on
Anduril-2 thread…

Convoy have M21C-U’s UI with ramping mode. I don’t have M21C-U but from what I read here it’s a very good UI.

M21C-U :

If there will be no full-blown Anduril at all, then this new Convoy ramping UI I think is very good and sufficient for most people.

That being said, i do really hope Convoy make flashlight with Anduril.
Maybe the new version of M21C-U : “M21C-U Anduril , and M21C-U Regular” ?
Something like Sofirn SP36 BLF Anduril and Sofirn SP36S.

Same idea as RapidLux’s :

No love for plain ol’ Narsim? My Q8s have it (except momentary mode, which I wish v1.0 had), my GTmicros have it, my ’minis have it, and it’s quite handy.

Even my DC7 has a rudimentary ramping UI that has most of the shortcuts (eg, press’n’hold for moonlight, 2click for turbo, etc.), that’s a sort of lobotomised Narsim. Definitely not it, but has the features that count.

Anduril/Anduril 2 isn’t going to happen based on current history. Simon’s driver manufacturer wants to obfuscate hardware used, and the license for Anduril won’t allow that.
