It looks like a lot of problems can be solved with checking tightness of the various components (i think the driving retaining ring being loose is a culprit), as well as cleaning contacts and making sure there isn’t oil on them.
What’s the one not working right actually doing when you try to use it?
Hi…. Go HERE . Read it, do what is says, and hopefully that will fix you up. :+1:
Totally agree….Love BBC news….well except for their funny accent but I tolerate 
Just in case no one’s noticed yet, a Nichia 219C emitter seems to be available in Neal’s website. No details as to what 219C was used though
OK, why are there so many LED versions popping up except for the SST-20 4000k 95CRI?
This is getting slightly annoying.
Oh that’s exciting! I wonder if they’re using TK’s 219C tuned firmware, the one that limits total output at like 50% to protect the emitters.
Also which emitter?? 4000k, 5000k, 80CRI, 90+CRI so many variables! I mean I’m totally ordering one but that’s besides the point.
I wouldn’t actually order one IMO.
We need to show our disinterest in other variants of LEDs.
Lumintop is trying to get us to forget about the existence of the SST-20.
TLDR: Only get the SST-20/XP-L HI version to show our wants.
I checked Neal’s site before leaving work today. That must have been added within the last few hours. Hopefully we can get a little more detail than just 219C.
I don’t disagree with this.
I’m definitely waiting for more info, but I am fond of the 219 series.
I’d also like to see them put out a Dogfarts version. Don’t get me wrong, I totally want to see a SST-20 version and a 5D version.
Can I just have everything?
Neal said there are no plans for a 5D.
Yeah, but I can dream can’t I?
The tuned firmware is for the 219B, which is much less robust at high drive current than the 219C. Stock firmware is probably OK for the 219C.
But what if I actually want a 219C version?
If it’s 4000K and high CRI. Otherwise I’m out.
Yes, we all should, and never stop.
I’m not sure what the deal is with 219C appearing in the store.
Neal mentioned it a few weeks ago, asking if it would be okay because Lumintop already had some available. I told him it would disappoint people and he should stick to what we promised everyone. That’s the last I heard about it.
The thing is, I would actually be interested in a 219C version, but only if it’s 90 CRI and only if it’s not above the BBL. My frosted optic Emisar D4 has an awesome beam profile, but I hardly use it because it’s so greeeeen. 
My Lumintop Tool Ti on the other hand has the most gorgeous rosy 4000K 219C in it, so I’m hoping Lumintop’s current stock is just as good. I still feel like it’s a massive gamble though.
I’d like the SST-20, but so far I have only encountered lemongrass green ones. If Lumintop can secure some with a much better tint, then I’d have these over the 219C. I’m starting to not care so much about CRI now though, as it’s very hard to find a high CRI emitter that can match an XP-L HI’s excellent tint. XP-L HI is always a safe bet for me.
because we still not found the SST20 and LH351D led
and a few people asked for the nichia version
so I add it to the list, lumintop will assembly some next week.
I echo this sentiment-ment—meent—~~(meeent)——(((meeeeeeent))).
Inclusive, not exclusive.
And if they RTF (mammalian)M they’d have em for longer.
Interested — so, what is the tint and CRI?
Thanks
