Well now i’m a bit miffed.
I highly doubt this is your primary desire.
Because when providing critical feedback it is necessary to provide negative “and” positive analysis. You have with others zeroed in on a series of subjective faults and dug a foxhole around it.
How about the candle. The thunderstorm effect.
The coolest feature i have ever seen in a flashlight. If your claimed want is to have fireflies succeed you did not sing praise on what has actually been a good thing, or a bonus feature or anything that will get the rotten taste of leaftye out of their collective minds or the minds of readers of this thread. If your supposed want is to see them succeed you have pooped all over their product publically. And maybe some have decided that this is the venue for that. BUT that is not wanting to see someone succeed that is peeing in their cheerios.
This makes you a narcissist and a liar. If you wanted to focus on fixing their design you should have reached out to them privately. You tom tom and lohtse should have all reached out privately to one another and or fireflies to discuss the problems. Instead of soiling the opinions of people just learning about this company or light.
You chose to stink it up with math and nuanced language to clearly influence people/noobs who may have taken an interest with the light/ company.
you made it about you
I got to be honest with you, i hold people like this in the lowest regard. I make things. I guess i identify with the makers more than the whiny crabby spoiled consumer types. So there is your apologist.
If you wish for them to do well you say the sorts of things you said in this public forum in a private message.
In public, if what you say is true you provide balanced criticism. You preface your arguments properly. There are alot of people who peruse these posts, certainly many do not require the level of specificity, and precision that you do—do not use technical specs the way you do, which would be swayed quite easily by someone who seems expert on the subject. You did nothing to help fireflies. In fact i submit that you did everything in your power to put a boot on their throat.
You can use words to say both sides of the argument without sh!++ng all over them or their product.
So, [for example] if you were looking for them to succeed, you could say it this way:
… for 50$ it is a sound light, the battery i chose to use does not fit well, the manufacturer provides a battery that i chose not to use. I did not design the light so i did not get a vote on which battery will fit, i am diasappointed that not all 21700 batteries will fit this light, it does seem like their aim was to make the light as small as possible though. However i should mention as we know there isnt a standard in place to keep cells a consistent size with a variance as much as 5mm+! Within the same format, at this early date we know of only a few proven to fit and this may be due to a production flaw and sizing of the battery tube. We are looking into it. Keep in mind the 21700 battery is a bit heavier than an 18650—DONOT drop battery into tube as the weight may dent your batteries positive contact if it drops down onto the spring. Instead slide flashlight onto battery. I really like the quality of the beam, although there is an artifact in the lens on my sample and at least 2 others, probably a machining issue (you did say this part!) But it does not affect beam in practice. The color of the beam on my sample is flat out marvelous. I could not test actual lumens but texastoast measured 1800 at turn on. This is to be expected with a 219b 9080 emitter, although it falls short of the 2500lumen listed on their site. In fact some were expecting 1400output based on the s41 so to get to 1800 lumens with this ancient diode is an outstanding accomplishment. It does get hot quick though as expected.the sst20 4000k was tested and shows 2520 lumens at turn on. /edit/: these mentijned are both listed as high 95cri emitters and komekos test of the sst 4000k shows below the bbl line so no green! Also newlumen reports for xpl 5000k at 3930 lumen at turn in which is a little less than advertised but 4000 lumens aint too shabby for a 3.5 inch lite. The size and shape of this diminutive light itself is fun, but i found the “pocket” clip too small to clip over my belt. the color of my sample is consistent but there is some evidence of rough handling that should get ironed out in later production. As this is early into the run. The user interface is simply aces. It does require a bit of commitment though due to the sheer number of things you can tweak. I particularly like the candle effect and thunderstorm, and being able to set floor and ceiling on the ramp function. Word of caution 2 clicks from off gets ramp ceiling. 2 clicks from on gets turbo. Kind of like a high and turbo. Manufacturer ships in muggle mode which is a safety feature you would let a child use—no turbo, so read your manual. Make sure you are using turbo for reals. Hats off to toykeeper, lexel, tom e and fireflies for putting together what has the potential to be a really nifty little light with expected astounding runtimes due largely in part to the new 21700 format batteries, we will try to iron out just what sizes will fit and have been in discussion with ff to provide rhis information on their site. If they get their production issues sorted out this might be one of my favorite picks for 2018, maybe even 2019.
Said all the negative crap with some positive crap. Balanced criticism. No wierd taste in my mouth, now.
