Solder some braid on the driver spring and that amperage will come up well over 4 amps. Mine has approached 5 amps and some crap started to smoke up off the dome of the LED, Smoking seemed to stop after a short time so I really think it was just some dirt/etc. I have since used a battery with more resistance to lower the power a tad to be safe.
Eventually it will get a Copper Sinkpad and new emitter.

Solder braid is made of copper, here’s a how-to:

I’ve ordered one of these, you know, because I do not have enough C8s already Wink

Welcome the night.

Copper,

I just found it a bit disappointing because I was expecting 4A+ stock.

Edit: relic beat me by seconds! Silly

Sorry, I don’t have a picture of it installed.
Look here for details on spring braiding ;

As somebody said, “Damn you guys are quick!” Smile Thanks for the responses.

Asked about the braiding thinking that no delicate soldering is required, thus even I can do it, my first ever modding. Cursory reading of the linked posts confirms that (even though tad more involved than I first visualized). Will order the braid first and mull over the soldering. Again, thanks for the ‘damn quick’ responses!

dang.. that desoldering stuff from radio shack is mad expensive.. you can get 2 of those for half price from fasttech.
but then again.. you get it right away though Silly

The only way to do a great work is to love what you do.

I got my light today. It looks really bright.

I was surprised to see it has next mode memory. Others here were saying it always should start on high. IMHO, next mode memory is the worst kind of them all.

I checked mine, and thought you performed some sort of bad juju curse upon it because it too was showing next mode memory.

But a few more tests later I found that the reset to high is approximately 8 seconds once turned off (Which is very slow compared to my other lights, normally it is around 2-4 seconds).

That’s great! I checked mine again after seeing your comment, and you are absolutely right. It acts like a next-mode memory when you don’t wait before switching it on again, but turns on high if you wait long enough.

I am really impressed with both the throw and very useful spill.

Does this light have a low voltage cutoff or a low voltage warning? Doesn’t seem to be indicated anywhere.

Thanks.

From green protected panasonic ncr18650b my light measures as follows
High: 2.6amps
Mid: 1.0amps
Lo: 0.18amps
using a $20 craftsman DMM.

The cables are 2-3 feet long, and 18awg.

Mine pull somewhere around 3.2A on protected iirc which is still comparatively low to other’s readings. I believe your leads may be limiting your readings though. I’m using 10gauge a bit over a foot long.

My readings are very similar! $5 meter off E-Bay, but replaced the leads. I am not into the ‘numbers’ but am very happy with this purchase and its’ performance. Hoo-yah!

Just received my Tangsfire pairs. Here are my rough results (stock).

Mode Unit1 (A) Unit2 (A)
H 3.24 2.62
M 1.3 0.97
L 0.23 0.14

Two of them yield rather different results using same NCR18650B unprotected 3400mAh@4.16V

Over-rated product?

Both of my units have dirty dome. Requires some cleaning.

Me too. I measured the amperage just for comparison reasons. Otherwise I am very impressed and happy with this light.

Anyone knows if I can get an 37mm OP reflector replacement? Does it exist?

Mine should arrive any day now. I think I’ll improve it and will give it as a present to a friend.

I was thinking about soldering some braid at the tailcap and changing the wires from the driver to the led. But what width should the braid be? And what diameter should the replacement wires be?

If the ones at Fasttech will fit, then yes. Smile
They are the ones used in Convoy C8 lights, if that helps. I do believe they are a standard C8 reflector format.

Welcome the night.

OK, once I get my Tangy C8 I’ll compare and try the fit.

I’m not sure either, but if the size is correct, I guess this one can fit Tang’s C8.

This is the measurements in the openings post:

The reflector is smooth aluminium, 35 mm deep and 40mm wide

Hope that helps
