Whaaaat???!!! That sounds suspiciously like a rational way to run a responsible and reputable business or something! Get outta here with that junk!

:stuck_out_tongue:

I found a handful of the 20mm TPAD quad MCPCBs the other day from when we moved, but I don't want to play favorites so I think I will list them and put the maximum order quantity at 1 per customer. I will count how many I have them list them and send out notifications at approximately 4 PM MST.

If you do miss out, remember that you can still order from Cutter or wait until we have our new production (hopefully in a few weeks).

Man that is excellent news!! Way to go Richard!! Are they going to be a dedicated parallel board or both?

I’ll wait for your boards!! :beer:

Any idea if you’ll be getting some 3000K warm white XP-L2 and XHP50.2 emitters in anytime soon? Preferably high CRI. They have some 80+ stuff on digikey I might get to play in the mean time.

Would also love to see a Convoy X3 host. Everyone needs more 26650 lights!

I do have some 3000K and 6500K XHP50.2 on order, but if you want really good color quality from edge-to-edge in almost any reflector then you don't want the XHP50.2 since it exhibits the same green/brown tint shift around the hot spot and fringes that the XP-G3 does.

In other words, if you don't want a donut hole in a smooth reflector, get the XHP50.2, but if you want color uniformity then get the original XHP50.

I'll have to see about the X3 host---that 26650 form factor used to be popular, but I have had a hard time selling them for the past year or so---they slowed way down, like maybe 10% of what they were 2-3 years ago.

Parallel, 4S, or 2S2P depending on emitter and jumper configuration, but only 3 jumpers in total instead of the million on the TPAD.

Thanks for the reply. I have a 5000k XP-G3 I got from your shop a while back which I’ve never liked, but I think that’s mostly due to tint. I much prefer warm white, <3500k.

I really like the increase in efficiency with the new generation, so I can probably live with the weird tint shifts if it is a good color.

Have an order with you for some 3000k XP-G3 bare emitters to try out to see if they are any better. Really want to try an XP-L2 also so I got the 4000k version you have up as well.

Sad to hear about 26650 lights, I’ve really liked them since I got my L6 and L2, but can’t see you keeping a stock if they don’t sell.

Oh man 4S…. Wonderful!!! :smiley:

Will you be getting Nichia 219C 3500K from Clemence? 4000K?

I don't know who Clemence is, but I have a reel of 219C 4000K 90+ CRI on order right now, so I will have those soon.

Great news, do you know if they are 3 or 5 step?

Do you have any 219Bs coming your way?

5 step. I still have 219B mounted, but no bare. Will be replaced by 219C.

That’s terrific!

I wish — hope — that you can make triples with some BLACK S3s.
Just don’t care for the grey.
Thanks.

Received my beloved TPAD quad MCPCB with 4 nichias on it, now my quad convoy M2 is running full!

Thank you a lot RMM as always it’s been a pleasure to do business with you

Any chance you’ll start carrying some of the single cell boost drivers that have started popping up on various Chinese sites?

Something like the H1A maybe?

H1-A and H2-C both look interesting

Big thanks Richard, refunded the added shipping for the extra order i added for some switches. A pleasure to deal with, great guy all round

Possibly. Those are a dang good deal, and the H1A is really really close to what I was going to build anyways, but I could never touch that price point. They are even using the same IC, even though they scratched the markings off LOL (TPS61088).

I’d pay double that to get 4 amps output, Bistro, and RMM customer service.

That board improved that way would sound tempting to me too.
Maybe modding those boards up to that better level could be worthwhile business?

When hardware has the markings scratched off, I always wonder, how long will they keep using the good stuff and is it likely that cheaper parts will be substituted eventually, with the same scratch-off obscuring any later change in what’s being used. Or does scratched-off identification mean they’re using some off-spec, seconds/rejects, of course …
