Not sure if this thread will be used to order by emitter choice or by number requested, but I would definitely like 1 more to be added to my name for a total of 2 with SST-20 as the emitters.

You want it good, fast and budget? Go ahead, pick any two (out of three).

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

That’s a total of 2, both with SST-20.

I’m leaning towards getting 2 as well (one of each). Please mark me down for another too, if it matters. Thanks. Smile

The following is from a relative noob's perspective.

Been lurking this thread since early on. This is my first group buy.  I committed to a light back in the early 1,000's (count, not Year AD) IIRC.  I did so mostly out of curiosity, with no expectations, so have not been disappointed with timing or anything else.

Fascinating process.  The challenges have been well documented IMO, and the issues with dealing through multiple individuals across different cultures have been educational to watch.

Kudos to all involved who selflessly spend their own time & resources monitoring the details, keeping the thread updated, and in general shepherding the thing along to fruition.  Thank You!

The discussion of emitters has been somewhat confusing to this writer, simply from lack of experience.  Modding is still some time in my future, so I'd like to make a good choice on the initial order(s).  Which brings up my question:

Could there be a synopsis added to post #1 that briefly describes the advantages and disadvantages of each emitter choice as related to this particular light/optics combination?  Nothing fancy, just some indication of CRI, total lumens, current draw and relative throw per emitter.  Runtime would be nice if only comparing basic modes but, the complexity would be daunting I suspect.  Perhaps links to deeper info per-emitter could be included for educational purposes for those like myself who aren't well versed on the finer points of the emitters being proposed.

I added an updated copy of the comparison used in the emitter poll:

——

Emitter Comparisons:

Price Lumens Throwiness CRI Beam Heat
Cree XP-L HI $36 2800? **** 70+ ****
Luminus SST-20 $30 2400? ***** 95+ ****
Samsung LH351D $30 2800? * 90+ ****

For price and heat, lower values are better. Throwiness depends on personal needs and taste. For everything else, higher values are better.

Throwiness is a rough measure of candelas per lumen. It’s the overall beam shape. Even the throwiest option is not a thrower, because compact triples are floody by nature. At a guess, the range here is about 2 to 4 cd/lm, and common reflector-based EDC-style lights are usually about 5 to 10.

Beam is the overall beam quality, like smoothness and color consistency.

More peppers makes thermal management harder, reduces the sustainable brightness after step-down, and increases risk of damaging the emitters on turbo.

Values indicate approximate performance in a Carclo 10511 optic using a FET for direct drive on 1×18650. These have not been directly tested in the FW3A host, so this data is more of an educated guess than a measurement.

All of the emitter types are good, but here is the worst part about each:

  • XP-L HI: Costs more. Medium CRI.
  • SST-20: Green at low levels.
  • LH351D: Super floody. Green at low levels. May be unobtainable.

Visual estimate of the floodiest option compared to a throwy option:

Actually, the heat should be the same for the LH351D and SST-20 since they have about the same forward voltage.

What is the need for adding that? The CRI for each LED is plainly listed. Am I missing something?

And I think it should be clarified with the two high cri options (without getting into specifics of duv) that their color is not as well-described as green as it would be if they were a cooler temperature, regardless of whether you say lemongrass or just say “yellowish/greenish color”. To me, the sst20 comes across more yellow than green, as I have probably mentioned.

At last, a good laugh from this thread! Thanks caramba, any opportunity to use that old meme is a good one!
I heard that the light will get done quicker once the thread reaches 10k posts, I wonder if there’s any truth to that?

Same Vf, same amps, but SST-20 makes fewer lumens… so it should also make more heat.

Uh, that would mean power is the same for both if the VF and current is the same?

I think heat should be based on power consumption.

All in all, the XP-L HI has the highest VF, meaning it emits less heat.

We then have the SST-20 65CRI which has slightly lower VF, consuming a bit more power, but not really enough to be significant.
Not available here, but would be nice for max throw.

Then, we have the SST-20 95CRI and LH351D 90CRI have the same lowest VF, consuming the most power and emitting the highest amount of heat.

If we’re listing the worst thing about each LED, it seems like performing far worse on a metric some people value highly might be worth a mention.

.

The power consumed produces two things; light and heat.
If one produces more light than the other then the one with less light output should be producing more heat, if the voltsage and amps are the same.

If it was possible to build a 100% efficient led all the power consumed would go into light output and there would be no heat.

It’s not low CRI; it’s just average CRI. Since you think it’s worth mentioning though, I added it.

I really hope they can get the LH351D!
The Super floody beam is much more usefull to me. Can not wait to get my hands on it. Perfect UI, high CRI, E-switch, super floody and very compact.
If it works without problems it will be hard for any other light to beat it as my new EDC.
Thanks to all that spend their time and work to make it possible!
