Great News! Congratulations Richard and Lisa on your new baby girl! :+1:

That’s awesome. Congrats Richard & Lisa! Children are such a blessing.

That’s good news. Congratulations Richard and Lisa, wish you all and your daughter the best.

Oh wow congratulations!!!

Congratulations!!!

Congratulations!

I have got a question about two of my MTNElectronics drivers: I mounted the 20mm 7135 driver in a cheap zooming light, it worked well for quite a long time but after I screwed it up recently there is only one of seven modes left. I already controlled for a short and unintentional direct drive but found nothing. My 26mm FET+7135 driver works well with an XHP70.2 but a minute after turn-on it starts a slight and continious annoying flickering. How could I resolve that? All suggestions are welcome! :GRAD:

And a hearty Congratulations to Mother and Daughter from here as well, I know it has been rough but praying y’all see a much smoother ride ahead. :slight_smile:

I have the new boost driver in an L2 pushing the XHP-35 HI and love it, very nice to be able to maintain the single cell form factor that I so love in this light and still get the great lumens and punch of the 35 emitter. Thank you Richard!

Congrats! We all know that the nursery will be well lit!

:slight_smile:

Congrats!!! :partying_face:

congrats.

Congrats Richard!

Do you know when you expect more qlite 17mm 6135 drivers? I hope you do plan on receiving more… used one in my last S2+ build and it works perfect.

Just placed an order with parts for a new build but still need a driver. Planning a Convoy M1 + 219C 90CRI + qlite. Although I just started reading about the LH351D and I may switch to that emitter instead since it seems to have a bit better output.

Oh, guys, BTW, Richard has put up for sale some high current Beryllium Copper springs on his website:

This means most people won’t have to bypass their driver springs anymore, and go on with their time.

Nice!

Oh, and while I was there, I noticed he also added Flat White LEDs (both bare and mounted) as well as spacers to fit the Flat White (7mm opening: Convoy C8, L2, S2+, etc).

My son and I assembled a 17mm MTN-BST2 Boost Driver Convoy C8+ with Cree XHP70.2 4000K. We added the $2+ extra orange peel reflector which removes almost all of the donut seen with the stock polished reflector. A homebuilt spacer with some widening of the reflector hole was necessary for this 7 mm LED of course. We ordered the full input/full output boost driver current options for this build, and on 100% output, using a Sony VTC we witnessed first hand proof of the need to bypass the spring. After some seconds, the output started to seriously sag at 100% out. When we went to add the bypass, it was obvious the spring had compressed. Richard said we likely got it so hot, it reformed itself. So we replaced the spring and added the bypass almost every post says is necessary. We don’t have a lumen meter setup, but we compared it to an L6 (2 x 26650) with the same Cree LED and a FET+7135 Driver. Against our back fence, the main light pattern is at least 2/3’s the size and at least 2/3’s the brightness of the big L6. We didn’t see any noticeable sag after 30 seconds when we decided that was long enough for us and turned it off. The C8+ does warm a bit, but has quite a heat sink head. We are pretty amateur at this, but this little flashlight sure packs a punch in a very hand friendly package.

Nice job. Good lesson learned with the spring since it’s an easy/cheap fix. If you touch it after you will notice its smokin hot. A high current spring or one that’s bypassed wont get hot at all.

Nice build. You could also try the beryllium copper springs, should be able to get away without needing a bypass according to feedback a few posts above.

Hi Richard, I was wondering if you are planning to carry the 3 volt XHP-50.2 that just came out here

Thanks!

I don’t know if this is appropriate for Mtn’s thread page or not but I was wondering if there was any interest from the group in the SST-20 LED’s (HCRI especially but also the high flux) enough to make it worth Richard’s effort. I foresee buying more of them a good bit myself. Same goes for AlexGT’s inquiry with the 3V XHP-50. Just a little feeler. Peace!
