BlueSwordM:
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.
.
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.

Huh, I completely forgot about that.
Thanks MtnDon.

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 1x18650. 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.
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:
Thank You TK! That's very useful for me.

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!

Probably asked before, but I cant find it. How difficult it will be to flash modified firmware to FW3A? Can it be done without disassembling and without soldering?

Hmmm… I click the link & it take me to the Tool AA 2.0
But your link clearly says fw3a-triple.
Either they are booking the page or they are making fake news

If it’s not too late I’d like to get in for 1 of these!

well if the model name appears in their page it must mean something… i hope not april fools joke i dont find that funny at all if so…
I know. It’s the worst thing I’ve done all week.

I have a slightly twisted sense of humor and I knew it was an April fools joke.
