Finally the XHP70.2 emerges!

Okay, that makes sense.

Dang, I was hoping a simple LED swap would give a boost to all drivers to a certain degree.

Oh well, we are back to looking at better bins to get higher output in that K60. Or get an L6 with fet and blow that K60 into the weeds. Lol

Well, you can still resistor mod it without going full direct drive. Although you will be “limited” to around ~7-8A, which is about perfect for most situations honestly.

The XHP70.2 should give a bit more output all else being the same and quite a bit more efficient wile doing it vs the last gen xhp70.

I like a P2 5000K upgrade. For that alone. I wanna see what they do in a MT03 - got one on the way.

P2 5000k 70 or 70.2? I have not seen either of these. Only seen the P2 in the cooler tints.

I think Tom have ordered a XHP70.2 from KD :

Interesting, high price and sad it is a 3B instead of a 3D but interesting for sure. What is the obsession with the B and C tints? It seems to be way to hard to find the A and D tints.

nice, looks to be designed to minimize that doughnut-hole syndrome of the past XHP-70. Hope they offer it in high-CRI N/W

I think the FX30 driver (Convoy L6) can be beefed up with a more substantial coil.

Correct. I have the XHP-50 Armytek Viking Pro and you almost can’t see the donut hole. With proper focus, this should be easy to correct—much more now with the .2 versions of these powerhouses!!!

What coil? I don’t think I’ve seen one on there.

The Inductor, the square thing a ma jig!!!

Oh, I got ya. I never knew what that was. I’ve never heard of anyone ever replacing it though.

Got a XHP70.2 today - 5000K P2 3B. Has anyone else rcv'd one yet? Debating where to put it. I'd like to try it in the Convoy L6 I have the TA driver in with the SMI reflector, or would also like to try it the MT07, but don't have a custom driver in it, but do have it resistor modded.

A member sent it to me from overseas, along with a SinkPAD. I'll post some pics.

If you use it with the TA driver, be sure to use very long and very thin wires, 24AWG is the largest I would use.

You will need some extra resistance for sure.

Uhh - what am I not understanding about this new LED? Can it be over amped and fried?

Under UV:

Under UV:

The MCPCB is not a SinkPAD, slightly thinner at 1.52 mm, but the traces are wider by far.

Yep!
Got both of them yesterday…

We don’t have a test of the 70.2 to know for sure but we can assume it is at least the same improvement as the 50.2. In which case we can figure it has a Vf of over 1V lower then the old 70.

Seeing as the old 70 could pull 12A a full 1V lower Vf could easily see these 70.2’s pulling upwards of 15-20A+ depending on the cells used. Even if that didn’t pop it you can bet it won’t be making peak lumens up there. I figure it should be around 10A for max lumens, so you want a fair amount of resistance to drop the power that much.

End point is that it running it in DD with low resistance is not a wise idea.

Ahh, ok. Cool KB1428 got some too. Hhmm, Could try it in the MT07 then - that's not DD FET, just little bump over stock.

Heres' that un-labeled MCPCB close-up. You should be able to see the traces:

Oh yeah, it needs regulation or wimpy batteries!

Well it will take just over 20 amps and live, didn’t turn blue, I don’t know for how long, I didn’t want to push it any farther!!! :smiley:

2S2P 8.37v

On 2S Laptop Sanyo REDs it pulled 6amps, 8.38v I have never seen them RED’s pull more than 8amps testing quads?

instead using thin wires it may be useful to add a resistor to limit the current
