Help with Sunwayman V11r Mod

Hi guys,

im planning to mod my new Sunwayman V11r. The Idea is to put in a Nichia NVSLE21AT LED (sm203) with VR16S1 MCPCB from virence.com. A fellow in TLF germany told me this should work but i have to play safe that the driver of the V11r only run with 2A.

So here are the questions:
1. with how much Ampere does the original diver run
2. does this setup work?
3. do the MCPCB fit into the V11r? I Somewhere read that only 12 mm or less fits.
4. if it doesnt work: anybody has another idea to get a real warm colour in the V11r, preferably with high cri?

Cheers, Michael

1. with how much Ampere does the original diver run

500 lumen maximun ANSI (OTF) = +- 530/540 lumen out of emiter = +- 1400 mA for a XM-L2 U2 Those are some very rough estimates.

2. does this setup work?

I have a Sunwayman V10R (original XM-L T6, the same driver that V11R) with a Nichia 219C 4000K, and it work very well

3. do the MCPCB fit into the V11r? I Somewhere read that only 12 mm or less fits.

Yes, máximun PCB 12,5 mm diameter.

4. if it doesnt work: anybody has another idea to get a real warm colour in the V11r, preferably with high cri?

The main problem is to “crack” the head of the flashlight without damage it.

I have modded several V11R’s and V10R’s. The latest mod I did I went with a LH351D 4000k high Cri in a V10R. I sanded down a 16mm Noctigon board I had that uses a xpg size footprint (3535). Several years ago I had already swapped out the led to a Nichia 219b 4500k high Cri and that was what was in it. I gained about 100 lumens just from switching to the LH351D. Produces, in my opinion a very nice beam.

Might be a option if your interested.

If you have not cracked open the light yet there is several methods used, you can use the search to find them.
This might also help with the packing grease. http://budgetlightforum.com/node/24407

Yes those boards sand down pretty easy with a belt sander. They are also thicker than the original that will need sanded down.
It’s a lot of work but you end up with a copper custom fit PCB board. For the connections just scratch of more of the trace (red masking) revealing the copper underneath.

Mtn also has a 10mm board that could possible work, I have never tried that personally.

It probably will have to be thinned some as it looks thicker than original also.

Question for the sunwayman modders. Are the walls of the battery tube thick enough to machine it to 18350?

I have a V11R on the slowboat and that is one of the mods I have in mind.
