What is a good tail spring for a Convoy L7? My goal is to increase the stiffness.
With battery tube extensions and 26800 cells installed, pointing the light slightly upwards causes the tail spring to compress and the batteries lose contact with the post on the driver. I want to be able to point the light up into trees without it shutting off.
I don’t think the L6 with 26650 cells installed is immune to this either, although the problem is not as bad.
Hard rubber discs wedged between as many loops as necessary. Each disc keeps the spring from compressing by that much.
I guess that would technically work. Where do you find rubber discs at? Also, not sure I like relying on something that is just wedged in place
Those stick-on doodads that you put on the bottom of furniture, rubber “feet” on project boxes, etc. You just get the right diameter (ie, big enough) so that they don’t slide out or get jiggled loose.
Maybe a block type eraser that you shave to the right shape, slice to the right thickness.
Maybe some type of faucet gaskets?https://www.amazon.com/dp/B09JKM1TCKd2lkZ2V0TmFtZT1zcF9uZV9kZXRhaWw
Probably not. You want discs, not toroids. Too easy to shift out of place.
Without opening a new thread let see if someone can give me an advice.
I already have a Wurkkos WK03 with Nichia 519A 5000k, would it worth to buy also a FC11C or I should expect a pretty similar results?
The WK03 is my only 18650 Flashlight and I’d like to have a second cheap one.
Maybe another WK03 with SST40 would be a better choice…
I want to take the chance since I’m placing the order for the TS28.
What do you think?
If Emisar and Noctigon flashlights are commonly called Hank lights, how come Convoy -NItlit ones aren’t called Simon lights?
I think I’ll start a new trend.
It’s unfortunate that Simon can’t trademark the MAO because it’s Micro Arc Oxidation…
At first I thought that the MAO torches he sells were named after his surname, then I found some other light of another producer with the same finishing named MAO and went to check out what the acronym meant 
I don’t have the FC11C, but I do have the FC11. I haven’t swapped out my WK03 yet, it still has SST40, I’ve been letting my grandmother use it.
I’m quite sure that if you already have the 519A version of the WK03, the only real gain you’d see with the FC11C would be a a little bit better battery life and regulation, due to the buck driver. I believe brightness would be about the same between both.
The FC11C is considerably longer than the WK03 but a little bit slimmer, pretty similar to the Convoy S2+. The switch on the FC11C is much better than the WK03 in my opinion. It actually has a nice click unlike the mushy switch on the WK. I also have an SC31 Pro which is the same externally as the FC11C but has an Anduril driver instead which some people may not like.
Are there any decent to good lights that have both a 365nm UV channel and a 395nm channel? I’m almost set on a D1K 395nm from Jackson but don’t want to carry two 21700 lights into the thrift stores.
Its main purpose would be for hunting UV reactive glass. I already have a 365nm Convoy S12 which is pretty nice. I could just buy a standalone light in 395nm, but I’d prefer a one light package.
Side note, if anyone knows how to contact u/SakowufSolutions outside of reddit which I can’t use, it would be appreciated. He builds just crazy UV cancer cannons and knows a LOT about UV drivers and lights, and I’d like to ask him some questions again.
As there are no stupid questions in here, and as it’s 2:50 am here, I am still working at a mega file and I am super tired, would you please tell me the practical difference between the two, please?
Curious why you’d need both. Anything that lights up under 395 would also light up under 365. Only those goodies that needneedneed 365 wouldn’t show up well under 395. Eg, the red strip on US 100s.
365 pretty much covers everything.
A lot of old uranium glass doesn’t really light up under 365nm, so that would be my primary and almost only use case for a 395nm light.
Huh… interesting.
No idea it was that selective. And to prefer a longer wavelength, yet!
Might be interesting to take a ww/cw light and replace the ww LEDs with 395nm and cw LEDs with 365nm.
OK, so I have a Convoy M26E that can pull 20 amps on the momentary turbo. I noticed that when my battery is at ~3.7V the M26E won’t do turbo. Currently I’m using a QB26800 that’s rated for 20A continuous discharge with a capacity of around 6800mAh+. Would a higher continuous discharge rating allow me to do turbo for more of the cell’s capacity?
I see vapcell makes one that is rated for 30A
Yes.
However.
The cell you linked to has less capacity. So would you get more total time at turbo?
Not likely.
So yes, if you had two cells with the same capacity and one had a higher discharge rating then you could get more time at turbo.
Most lights/drivers are not going to run turbo once the resting battery voltage gets down to about 3.7v. CDR is a factor. Voltage sag is a factor.
The driver is looking at the actual operating voltage and is going to start reducing light output at 3.3 or slightly higher volts. Of course there are variables with different drivers.
It seems like the driver might have some kind of hard cut-off past a certain voltage where it won’t turbo. Does that sound right? I guess I’m just curious if the lack of turbo is because it is mathematically impossible or if it is a programming choice.
I have used Emisar lights so much I’m more used to the behavior of FET turbo where you can always turn on turbo but it can turn out to be dimmer and will eventually be equal to max-ramp.
I believe this is the driver:
It’s a buck driver - it only lowers voltage to match cell output with LED Vf, it can’t raise the cell’s voltage - so if the cell’s voltage sags below the LED Vf at given current then it can’t provide that current.
A higher discharge cell means less voltage sag, which helps but You can’t completely overcome this limitation and have turbo available over the full capacity of the cell. That requires a boost circuit. And in case of single 3v emitter setups that would mean a buck-boost driver which equals complexity, cost and inefficiencies
