i find the original the best, 3 emitters is more then enough… 4 is just i dont see the point really… not like it can sustain the highest lumens anyway… it seems the models are getting out of hand now… whats next 5 emitters or like fireflies 7 ??
but nice see u back making videos matt…. 
I’m most interested to hear about efficiency numbers, sustainable numbers etc, the fw3a isn’t exactly very bright if left on. Also compared to the fw21 which appears to be a little better, but I’ve got different leds so it’s hard to tell.
Finally, is the battery tube and rear switch the same? Eg. We can use short tunes and existing set-ups and swap the heads?
I can already seeing myself getting so many fw3a/fw1a/fw4a? lights in flashaholic lego fun 
If it can run a higher sustained brightness and I can mix and match with my existing parts, I’ll def get a 219c and/or even an xp-l hi!
Just a pity my fw21 can’t be involved.
great review, thanks for this video
It is a lego able part. Works with the 18350 bodies etc. Its not going to be any more sustainable in the high/turbo modes.
This. If it was a 21700, I would have purchased.
Thanks. Good to know it’s compatible, already got a good collection going
Obviously it’s going to heat up even faster at high levels (like it needed to be faster), but given the efficiency curve of leds as well as a slightly larger head, would it be incorrect to assume that it might be able run at a slightly higher sustainable output? Eg. ~250lm instead of ~200lm?
Or is the level of sustainable output so low on these devices that the efficiency of higher output isn’t even going to come into it?
Love your videos mate, thanks for all the work!
Stay safe, we are all thinking of our American cousins right now.
Unfunny joke. Not usable turbo. Paper lumens, unreachable on real use battery, and immediatly stepped down by thermal control.
Nothing new, no new ideas.
That’s true of all EDC-size hotrods.
Not every light has to reinvent the wheel, having options is okay.
It’s cool, in that not too long ago we couldn’t even imagine a light like this in this size, but I honestly don’t see any advantages over the triple. Maybe it is just to compete with Emisar?
Still no USB. Is it really that hard to add built-in charging?
It is if you don’t want to redesign the whole light and make it a whole lot larger.
They could have added a couple of mm to the fw21 while they were at it if they had wanted that.
But you can’t add a port, controller and wiring into something this small without making it larger and incompatible with existing parts.
OMG. WHat’s the difference exept additional led, 4 against 3.
Something changed?
Same design, same driver, same leds. Lets put inside fifth one. And sell this stuff again as new awesome flashlight, best of best
The FW5A - yeah, I gotta have it!
Not everyone like built-in charging. Size of the flashlight need to be increased or thermal mass decreased (space for new compomponents on driver and charging port). Also space on driver is limited so some extra board would sometimes be needed. This can also affect thermal regulation as flashlights usually use internal attiny functionality for that.
Facepalm……
Even EDC18 with 3 LED with medium current cells like 35e takes from them around 8A on turbo and makes itself hot in count seconds.
More led’s shift Vf and on high current cell flashlight would be overdriven like crazy horse and stepped down in seconds. So what for such actions? If you need real power - just take a little larger flashlight.
The advantage of a pocket EDC is that you have it on you. Unlike a larger light, which you may not have brought along.
A small pocket EDC can always be run at low power for sustained output. But it’s really nice also having the option of being able to go into “ludicrous mode” turbo if you need it. Sometimes you just need a lot of light and being able to only sustain it for 10 seconds may be enough. Or maybe you just want to wow your friends.
Put another way:
8 minute abs? How about 7 minute abs?
Is this different from how most products are released with only incremental changes?
Nobody has to buy it.
I feel happy when there is another person on planet earth who has a similar thought as I do.
"Is this different from how most products are released with only incremental changes? Nobody has to buy it."
I bought this light for all of the several usual happy reasons that I like, even though I already have bought the three emitter version of this light. Yet another reason: To continue to help support the spiritually advanced community of people who helped design it, and the manufacturer who makes this light.
