FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

I don’t know if it is possible, but I agree that the poll shows that having both XP-L and Samsung choices would make the most people the happiest. Although I prefer the XP-L, I would probably get both in that scenario. My wallet is hoping against this.

Thanks for checking! Yeah, pretty much seems like you said, the 2 emitters and the 2 temps.

LH351D 4000k/5000k

XP-L HI 5000k/4000k

And done! :slight_smile:

contactcr make sure that iso, aperture, and shutter speed do not change through your test regardless of their values or how you found them.

The point of my video was mostly that while beamshots can show the relative intensity of two or more beams, their shapes and qualities, etc, they don’t reflect how much intensity is actually required- if you ramp up from zero and stop when you’ve got enough light to see, you’ll usually find that you don’t go near the maximum brightness. However, you might find yourself wanting a wider beam - I know when I was in the woods in my test, the d4 219c beam was too narrow when it came time to get my bearings again.

Edit: You might try exposing for the least intense light in the comparison, rather than the most intense or a random middle pick.

To be clear, none of the options are bad. All five are great choices, even the old but venerable XP-G2. I’m pretty happy with my triples in XP-G2, XP-G3, 219b, and XP-L HI. I don’t have any triples with 219c or LH351D, but my 219c quad is nice, and everyone with a LH351D says it’s awesome.

If we can get more than one flavor made, I plan on getting every flavor.

In that case, it’s probably especially important to maintain a practice of humility and remembering what it’s like to be at the bottom. They say (and studies show) power corrupts… and, as Spiderman says, with great power comes great responsibility. Gotta be extra careful to avoid bad habits.

Any decent cell should work, though higher-amp cells like the 30Q and VTC6/VTC5 should make turbo a little brighter. On regulated modes, the highest output is only 3 amps, so most cells should be fine most of the time.

This light isn’t optimized for maximum turbo performance. The heat sink isn’t massive, the springs aren’t fancy low-resistance alloys, the wires aren’t extra-thick, etc… It’s not particularly hot-rodded.

The main thing is to make sure the cell is small enough, so probably an unprotected battery.

There isn’t a lot left to do, and progress has sped up again… so hopefully release will be soon.

The 10507 has the biggest numbers on paper, but…

  • It makes an ugly beam. I hear it looks okay with LH351D, but on every emitter I’ve tried in one, I end up hating the beam. It produces a rainbow effect and lots of artifacts.
  • The 10511 can be polished to increase throw, if desired, and from what I hear, it can throw better than the 10507 after being polished. Afterward it has more visible artifacts, but the beam still ends up looking nicer than a 10507.
  • Swapping the optic is easy and the parts are only about $1.50 each, for anyone who wants a different optic.

Yes, having data helps with convincing the manufacturer that a market exists for both. :slight_smile:

I kind of prefer the Ranked Pairs algorithm over Schulze/beatpath, but RP hasn’t been working lately on the CIVS site and the results are almost never any different, so I went with the more stable more popular option. I’m using RP locally though. It’s simpler, and it was easy to find existing code for so I wouldn’t have to reinvent another wheel. I just had to mod the input parser a little to accept the format I get when pasting data from the CIVS site.

For XP-L HI, more CCTs are available… so that would probably be 4A (4650K). But for LH351D I need to look at the data more closely to see whether people want 4000K or 5000K.

The LH351D in both 4000k and 5000k have been tested, both by Maukka and djozz. And from them, they said that the LH351D in both color temperatures was awesome, about as good as the Nichia 219C and Luxeon V.

I only have the 4000k R9070 version of the LED in my Thorfire TK15, and it is truly awesome, and makes for an awesome EDC.

Put me on the list please

This is why I’m on the list for four of them. I’ll do it myself.

I’m very much a CRI snob though, so probably no XP-L HI or XP-G2. I can’t not have a 219C version of course, and I’ll very likely try the LH351C, which Digikey has here in single quantities, 4000K, 90 CRI. (I know the page doesn’t list the CCT and CRI, but Octopart does.)

:person_facepalming: …. My, my, my…… :person_facepalming: … :frowning:

Forgive my ignorance, but who is Nellie the Elephant?

Beats me… I myself am also at a loss of any significance associated with that ’statement’ made by Tom Tom.
BUT…… fwiw……I did find a picture of “Nellie”. :person_facepalming:
.

I hadn’t heard of this before either, but wikipedia has some info. It seems to be a song which played on BBC radio in the 1950s and 1960s. It lists this for lyrics:

FFS Nellie is trumpety trump.

Here’s a vid:

I’m surprised I needed to mention this.

It’s a bit laughable in most regions, we like dumbo too who can fly with his ears.

Well, if nothing else, she looks like someone my niece would be fond of. :stuck_out_tongue:

Too funny :smiley:
This is what happens to threads when the waiting is too long for our torches :slight_smile:

As far as I know, Toy Keeper isn’t from the United States. Maybe I’m wrong.

Which is why your comment didn’t make sense.

I asked to be added to the list for one at post #1970.
Checking back in 5 months later to say I’m still interested in one.
Thanks
Russ

You are still on the list at #852.

Despite being 1/4 Welsh (my middle name is Wynne) to my shame I don’t speak the lingo. The UK is really quite a diverse country with several languages. English being the common denominator, which helps.

Swearing and cursing is fairly universal though, even if we don’t quite understand each other the meaning gets across…

Well, I know of a few stand-up comedians across the big pond. If you could filter out all the rude words from their shows, you would be looking for a stand-in comedian to fill the time after the break.

Edit: I do enjoy watching “A night at the Apollo”.
