Has anyone tried to fit an mt-g2 in the light?

Did some mods to mine yesterday.

Recap mine was pulling 2.11amps on high with a KingKong 26650 INR.

I was disappointed with the throw and colour despite the good amp draw.

First thing I did was the pencil mod which I hasten to say worked brilliantly. I then moved the red wire to the output1+ with no other changes.

It was now pulling 2.86amps on start up and just over 3.0amps after about 20 secs.

The beam was still horrible though.

I then removed the reflector and the driver and NOTE the led just falls out. There is nothing, no thermal compound or anything holding it in place. The only thing I could see was something that looked like a few drops of something oily.

Next step was to fit an XP-G2 NW on a noctigon. Anyone else doing this I highly recommend using a 20mm star. I only had a 16mm. In order to get the reflector to clear the solder points I have to file the square edge off of the outside of the reflector base. Sadly it still just fouls the solder points, but does allow the white centering ring to seat on the star now. Ideally I’d have liked not to use the white plastic centering ring.

I beefed up the wire (20 or 22 gauge I think) and resolder the driver.

It now pulls 2.46amps on high (showing that an XP-G2 does indeed pull less amps than an XM-L on the same driver, not sure why, but have seen this on 3 other XP-G2 installs).

The colour is obviously way better and the beam is improved. Sadly I didn’t get the XP-G2 perfectly centered, another reason to use a 20mm star if you have one. But throw is massively improved, it now easily out throws my Imalent DDR2 XM-L2, which it was nowhere even close too before.

And oddly the white centering ring seems to work quite well with the XP-G2 giving an almost XM-L sized hotspot.

Overall I think the light is much improved for these changes, which really has only been a LED & star plus moving some wires about.

Thanks OL for the group buy.

I was fiddling with the reflector last night. The focal point seems to be ~3mm below the base. Can anyone confirm that? That's why they use such a tall centering ring. 

I had tried removing the centering ring and substituting a 3mm thick o-ring. The beam was very floody. At ~40m, shining into a tree it was almost indistinguishable from my Convoy S6 w/XP-G2 S2 1B @3A, side by side.

These are great lights…ready for either basic “tweaking” mods to all out barn burner mods

So far I have just done a very modest mod and this thing chucks some light, even using el-crapo and probably wore out laptop pull 18650’s w/ adapter

Recommended basic “tweaks”

  • pencil lead next mode memory fix
  • move wire to other side of resistor bridge pad for extra power to emitter
  • heatsink compound under star
  • replace the large centering ring (or shave it down)
  • solder braid on springs

Would I be able to put in the 20mm FET driver or will it slip through?

Wasn’t sure since the shelf looked to be a little wider. Can I order just one of those complete?

The hole in the shelf is definitely >20mm, I measured. There is no one currently selling populated BLF 22DD boards. I don't think anyone has received one yet, WarHawk-AVG only just shared the widened version 2 days ago. If you need one built up I'd talk to RMM - http://mtnelectronics.com. He's already assembling BLF20DD drivers for $14-15 here.  I would expect lead time on the bare boards from Oshpark to be at least 8 days.

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

I contacted RMM and he told me if I wait a few weeks he can get some boards to build one for me!

Thanks for the help, and I will be looking forward to receiving this, if nobody beats me to it I’ll make sure to get some photos and numbers.

Sure. If you can’t wait and are able to solder a little you could always order a built BLF17DD or BLF20DD from RMM now and install it using an adapter ring as discussed in this thread. Take careful look at my shared projects on Oshpark to select the appropriate boards for you. The 26mm v11 is the most versatile (when filed down to various diameters), but the 22mm v9b will require the least work. You’ll get 3 boards when you order, so it’s up to you to figure out what works best for you.

Awesome, looks like I’ll get some of those now, I’m sure I’ll eventually find a use for three of them.

You all really do make sure no problem goes unsolved! Thanks!

Sanyo is fine but that cell has no protection. Maybe a new thread so others can benefit from your questions? They’ll never find this information buried here.

You made me laugh out loud. Do you normally have slow mail in Romania [I assume that’s Romania], or is it just a sucky experience this time? I bought into the GearBest dreamcharger GB the other day, so I’ll see how my second experience is with them shipping to the states.

I wouldn’t say it’s unusually slow. Things come from Asia in 10 days or in 40 days or anything in between. It’s a lottery really. Glad I made someone LOL.
Best delivery was when I ordered a 2K monitor from S. Korea. It arrived in 3 days flat and was about 400 dollars, so i guess DHL was included.

I was told by GB that all the lights had shipped. That was a couple days ago. Whatever "all the lights" means, I don't know.

Big Smile nice one OL. It’s not that i blame GB or anyone really, I am sure they shipped but I think that a lot of online stores use freight forwarders in China and that overcomplicates the whole process. It shouldn’t take more than 15-20 calendar days from them to anyone.
And I know this light is a light worth waiting for Love

I trust that by the time mine arrives, everyone will have tried all the various possibilities for improving on it and posted them. No rush about that.

Got my 2 today, after 33 days from order. One came with a 3 AA carrier - weird, the other one came with two 18650 adapters - again weird. Free extra parts I guess.

Need a 3AA and don't want to wait for it to get here from china.  Hit a local store and look for 3AA lights on clearance.  Something like this:
