I just picked up I Zoom Farpoint 350 zoomie with COB. The exact same as revised version of Tactight. For $8.50 and last one I took chance. We will see how it works ot.
There are a few others out there.
I have 4 different 1x AAA zoomies.
This SkyWolfEye is the slimmest i have.
I modded it with a dedomed XP-C $1.78 AAA zoomie XP-C dedomed
There was a later model from SkyWolfEye some time ago, a bit wider head and matte black finish.
Seems it was only available for a short while.
Has a slightly better lens too.
But they’re all quite crappy really…
With regards to the UniqueFire series but not limited to I could also say “as if there aren't any larger drivers out there”.
17mm is too small to embrace the majority of fully regulated buck/boost stuff. Lots of lads still are stick in the mud with their same old unregulated MOSFET PWM 7135 story. But lads ought to understand their feet will continue in the mud unless they decide to endorse further development of proper drivers. This is about fostering what we want instead of letting others deciding for ourselves.
FET DD is not bad choice for some users. You would not believe me but they can withstand some serious abuse plus they are simple to build… Other than that you also have linear 7135/7138 17mm drivers that could fit and not only that I had 17mm buck drivers at 2007 so did they disappeared from market?
Ok you eventually got 17mm buck driver and now you have problem of fitting it cause pill inner driver space is to shallow? Or in other words you think pill is not deep enough?
Solution is very easy. Just extend depth of such pill by adding those 17mm brass driver holders(you can stack them to desired depth).
Never I complained of driver unreliability, but a MOSFET DD driver is like no driver. There's nothing inside of it which takes care of matching its output to the characteristics of its (led) load. Because of this the chain of electrical components inside the flashlight needs to be attuned to prevent undesirable results.
The 7135 linear regulators are not meant to be fast PWMed and have a fixed current output of 350mA per chip. No good.
Why is the above still prevailing? Availability, cheapness and probably because people knows no better.
There's some good linear drivers using MOSFETs in regulated linear mode, like led4power's offerings and the aforesaid LD-25.
Among the available buck and boost offerings lots of them are turds with undesirable characteristics like too much sense voltage (bad current sense designs) or lack of some desirable feature like undervoltage warnings.
The majority of desirable buck/boost drivers which I know of are ∅20+mm.
One thing I like a lot from a fully regulated flashlight setup is it always goes full throttle when I want it, and independently of battery state of charge.
Just some. If I am to compare the main flashlight driver technology you're using versus some of the software you're making use with them it's sort of like running MacOS 10.1w/Windows 10.w on Motorola 68020/Intel 80386 powered systems. You get the idea.
Hey guys, is there anyway to get rid of the ” shadow rings ” once light is fully zoomed in? What I mean is a economical fix. The ones I want to fix are Harbor Freight Quantum 588 lumens, I Zoom Farpoint 350 lumen ( same as Tactlight deluxe version) and Tasco bought from Sam’s Club.
Lights were $10 and under so I do not want to invest too much into it,
Black electrical tape or black epoxy or nail polish or something like that around the LED MCPCB.
Also on the inside of the heat if it’s not all black already.
