GB Clone Offically "SOLD OUT" 10/21/18 XPL HI 1300LM Focusing AKA Cometa 2016

@Barkuti

Otherwise, take a look at the NVSL319A and NVSW319A offerings at Clemence’s shop.

Up to 1400 lumens at 6A with good cooling does not seems to be bad, but throwing wise it depends on its actual die size and if dedomed or not.

Yeh, saw the graphs that Koef(?) put up, like, last year. Seems to be kinda inefficient compared to an XP-L2 or so. I didn’t want to cook the beastie too badly, so wouldn’t want to go beyond 4A or so.

And cut the lumenage down to a third for a more realistic light-on-target…

One of the Cometas I got today had a Bat Signal that was horribly “smeared” in 2 directions. Cleaned off the lens, got off an obvious greasy fingerprint (on the flat side!), looks clear now, but still got the “smear”. Wonder if it’s mounted off-axis or something.

The one I’m using now has an offset faint circle around the Bat Signal that’s due to the lens sliding around. Loosen the bezel, poke the lens from the side, and the “halo” jiggles around, and a poke in the right direction makes the 2 concentric, ie, no more “halo”. Try holding it in-place while tightening the bezel, and forget it, it slides right back to where it wants to be. Not a big deal, as I can live with that, it’s so minor.

But the “smearing” on this new one is horrible. It literally looks as if someone inked a pic of the lit chip, and smudged it in one direction then another while the ink was still wet. Fiik what’s making it look that way. Will have to try disassembling it into pieces to experiment with it.

Worst case, I’ll sell it to some unsuspecting widow/orphan.

Whups… ’Twas TA who done it.

Nichia 319A D440 Output test by Texas_Ace; Hex die LED gives a nice beam

Ok, like normal, tests done the same as all my others. This is the new Nichia 319A LED with the new Hex die. I put it through the test and the results were not quite what I was expecting but also not that far off. Marginal improvements over the 219C in a similar spec. Large die means less throw and more flood if that is what you are going for but it also means a nicer beam pattern, particularly on optic based lights. I think it might be thermally limited as when compared to the 219C it falls …

Got my CSLNM1.TG from L4P in the mail today. :+1: :+1: :+1:
I went the lazy route and ordered them already reflowed.

Here’s the issue: the original copper star is 1.6mm thick, about 0.2mm thicker than L4P’s. Now the retaining disc bottoms out on one of its lips, either against the pill or the body. (There’s not much difference between them.) Nothing puts pressure on the MCPCB.

Quick fix: Put a 0.2-0.3mm spacer between the disc and the MCPCB. But now the inner edge of the disc gets hit by spill, leading to an ugly beam.
This would also happen if you have cut threads to screw the MCPCB down.

Proper fixes:

- a sheet of copper (0.2-0.3mm) between star and pill (or alu, or graphite)

- a thicker MCPCB

• cutting down some of the surfaces (either pill + body or both shoulders of the retaining disc) so the disc can screw in deeper

I think even stock it was on the loose side and the innermost ring of the disc didn’t go down all the way, and pressure was mostly on the wires.

Good point!
I’ll use the stock LED board or one of similar thickness.

Wonder what the bezel made of, I use the same method (10 Min in Sodium hydroxide+sanding) of both C6F and CPF but look at the result.

banggood did again! cancel my order two weeks later.

Ditto also order cancelled today by BG. Surprise surprise, there were plenty still in stock when I ordered just one, from CN, as an experiment.

Still 134 left in UK warehouse (allegedly), but I won’t be biting at £21.41 (supposedly 50% off). That’s about $27.

I had hoped that they would just have sent one from the UK, to me in the UK, at the $15 price. Same things have happened before, in 3 days. But that was obviously too obvious this time, or they just wanted to back out from “the deal”.

Meanwhile they can hang onto the UK/EU stock and slowly slowly get rid. Selling to anyone who doesn’t know how to do a search.

Or am I making a mistake and missing the biggest bargain ever ? Depends how you value your time and effort. IMO easiest just to buy the real thing for a few dollars more. First World problems ?

I don’t think so. Dodged the bullet I think.

I think the weight might have been a clue if so

My guess is that the caustic was not strong enough or left long enough to get all the ano. off. If so, reassuring, indicative of a good layer. Try again, I’d say.

My order was also cancelled.

Bummer.

It is really bad how BG handled the complete thing!
In total i ordered 3 Cometas one with battery (was refunded because they were sold out). And two without battery (one was delivered and one refunded).
I asked if they could send one from the UK warehouse instead of refunding but that is not possible! They have to refund but then i could buy from UK warehouse again (for ~2x the price. Really? Sure? It will be my honor! I am sooo thankfull! Yeah will 100% do so because i am really stupid! ! !

So far, mine is remaining in the SHIPPED column on the Banggood site. :+1:

• Ordered 18 October
• Shipped 25 October

[HONDARIDER]

Guess I was fortunate that I got all 3 of mine. Ordered 2 one day without the battery and one with a battery the next day. Just got the one with the battery a week ago. The 2 without a battery were received almost a month ago.

@TheOnlyDocc

Yeah. While I got all mine can’t complain about that at all, I’m still soured on ‘em, not just from my own experience (the whole battery runaround, getting screwed on shipping, etc.), but others’, too.

[Tixx]

So I ordered 2 and they have arrived. Reading through parts here it seems like these may be dangerous? I have the plastic spacer ring thing in there and it says 2016 on the bezel. But not sure if I should continue using. Any suggestions appreciated. Thank you!

[X31 (-X3-)]

I tried to “dye” the plastic washer to get rid of artifacts.
It worked like a charm, I burnt some cheap paracord to make some black fumes and placed the washer on top of it so the fumes would stain it :

No I have to make the second one. Its cheap and efficient !

EDIT : oh, free beamshot as well (White Flat inside)

Read through the parts that outline the very simple ’fixes’, do them , and you will be just fine. .

[TheOnlyDocc]

I really do not know whats going on at BG!
Ordered 3 days ago and now the next mail arrived:
We regret to inform you that your order was returned due to the failure of security check when passing the customs office.
I ordered a update for my bench powersupply so i am able to test leds that require more than 5amps (limit of my Bench powersupply).

Great idea with the para cord fumes! :laughing: :student:
