Thank you for your video. I think this is a natural progression from the FW3A, which I like for several reasons, one notable is because it has a rear electronic switch.
My dentist has been bugging me for a few years to stop mouth holding single 26650 lights, so I downsized to two nice single 21700 lights, but as much as I like mouth hold (and those two lights), my dentist is still not happy with me. So, this looks like the King of rear electronic Mouth Hold Lights that won't cause malocclusion.
To be honest, i am getting sick of the fact that the FW3A is made available in that many form factors.
It looks like they are making every possible composition trying to milk out this light and design.
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 ??
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.
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.
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?
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.
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.
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.
