4/11/19 Important UPDATE! Cree XHP50.2 Three Volt!! Convoy C8+ 3000 Lumen

~~X3~~:

Agro:

I’d like to see it in some small lights, all the way down to 10180.

Well, this LED is justified when you reach 8+ Amps… So it doesn’t really make sense.
If you want a 10180 hotrod light, an SST40 is enough

Nah, lower Vf of XHP50.2 will overdrive the cell more resulting in significantly more power. From djozz SST-40 has 3V at 2A while XHP50.2 has 3V at 4A (calculated down from 6V).
A tad higher efficacy won’t hurt either. At 1A SST-40 does about 500 lm while XHP50.2 about 550.

Excellent,Evolving,Educational,Entertaining and Enjoyable!

I have some on the way from Cutter to go in an S2+.

nkresho · 2019-04-06T00:53:04.000Z

s2+ needs some current limiting to be “useful”, IMHO. Way too hot, way too quick. It’s similar to a triple XPL build, fet driven, in the same host.

Not that I say don’t do it, i’m not taking mine apart, but… I promptly put it in the box next to my triple s2+ and triple s6, which never get used.

Nice mod, thanks for sharing, I wonder how would that look on the new FT03…

Do you have any other tail switch recommendations that will work for a longer life span? A drop in type.

16mm Complete Reverse Clicky Bypassed Switch --- C8 / S2+ / E2L

If you want a true drop in no soldering required then get the above. It’s basically the same thing but it has a genuine Omten switch (a non-convoy C8 clone may not) and it’s bypassed already so no spring problems.

Do you have a recomendation that requires assembly that would be better?

contactcr · 2019-04-06T03:57:03.000Z

Not really. Myself and other modders use Omten switches bypassed at high current often without much trouble.

cabfrank · 2019-04-06T07:17:00.000Z

I really want one in an Eagle Eye X6 host, but I know it would get very hot.

You can put high current over those switches for a while(not sure if genuine otman es better than factory c8+ or not), and the bypass does help (keeps the spring from loosing is stretch). Most of the time when your running this light it would not be at 13.5 amps, and when it was, only in short bursts. So if your not depending on that light for life or death it might be worth a shot. I don’t know of a better “easy” switch option this small. Making a switch out of a Judco like DellSuperman does for surefire would be the closest thing I can think of.

I have some springs from BlueSwordM that I could put on it. May handle the current for a little longer. Your right, I wouldn’t be running this on high too often. So it should be ok.

BlueSwordM · 2019-04-06T15:29:07.000Z

The springs are not the limiting factor here, but the switch.
Even if you were to put dual BeCu springs on the PCB, the

You could try and bypass the switch itself with some 24/22AWG wire, but you would lose selection outside of turning the tailcap.

That’s the only other way, other than building a FET switch.

contactcr · 2019-04-06T15:30:42.000Z

One thing to be careful of when u swap the spring is getting the switch too hot. It will melt if u heat the board too much.

You can desolder the switch before if you want to be extra careful or put metal clips on the switch legs to soak some heat

Hmm interesting, I never had must interest in the XHP50 before because it seemed inefficient.

How does this new 3v XHP50.2 compare to say an equivalent XP-L2?

BlueSwordM · 2019-04-06T16:59:10.000Z

It’s basically 4x XP-G3s on a single substrate.

So it’s about equivalent to 2x-3x very high binned XP-L2s.

Seems like they aren’t using very highly binned XP-G3s though.

Seems like it’s the XHP70.2 getting all the good dies.

Lightbringer · 2019-04-06T19:49:04.000Z

Nice, but I so want one of those switches!

CRX · 2019-04-06T20:43:49.000Z

Need to figure a way to make it click on.

Impressive. What’s the main downside (if any?) compared to the XP-L2 or G2 then? Less efficient?

BlueSwordM · 2019-04-07T23:33:44.000Z

Well:

1. Basically a smaller XP-L2.
2. Compared to the XP-G2, it has less throw/lumen.
3. Tint is disgusting, with a rainbow beam.

LarryLumens · 2019-04-08T01:36:44.000Z

Does anyone know how many lumens the new Convoy C8+ with SST40 is pushing? It is as bright as my Sofirn C8f but flood vs throw can trick the eye.

Impressive. I think my favourite is the 50.2 dome on.
