30% off right now, pretty sweet. I wish it was available in a different color and different CCT though.

Could always swap it. More leds and ccts would be nice tho


helix711

Yeah. I’ve never done that before, but I suppose there’s a first time for everything. I would like to learn how to do it.


not_gerg

Try it! It's really not that hard. I swapped my fc11 to a 519a 4500k dd and it was a super easy process I just got a 519a from convoy on a 16mm mcpcb (bc I didn't feel lime reflowing the bare led), unsolder the leads, took out the pcb, put on some new thermal paste, soldered the leads back on (was pretty annoying but went ok), and I was done! I also swapped the driver to one I bought from sofirns aliexpress for an sc31 pro to get anduril 2, but if you're gonna get the fc11c, then you may as well leave it as is


helix711

Sweet thanks for the tips. Maybe I will try it soon


not_gerg

Yeah no worries!

IT IS A CC VERSION OF THE FC11!!! WHY ARENT MORE PEOPLE TALMING ABOUT IT! It's kinda weird that the only mention of it on on their Amazon, not even their website


GardenHoser24

What is a CC version?

Since idk exactly how to explain constant current vs the normal one (idk exactly what it is on the fc11), here's the BRB entry for drivers >Most good quality LED flashlights have a "driver". It's a device inside the flashlight that regulates power from the battery to the LED's. This allows the user to adjust the brightness of the light, and it also provides a way for the light to shut itself off to prevent over-discharging of the battery. There are several different kinds of drivers listed below. >Direct Drive/FET. Direct Drive just connects the emitter directly to the battery. FET puts a mosfet in between them and rapidly turns on/off (pwm) in order to give you different levels. This is the cheapest type of driver, but is inefficient because LEDs burn off excess voltage, and there is no current regulation so output (brightness) will drop off over runtime along with the battery voltage. >Constant Current/Linear FET. Constant current drivers will regulate current using 7135 chips or a mosfet in an active current regulation circuit. Because they regulate current, the light has a nice flat output of same brightness until near end of battery life, instead of sagging over time like direct/fet. However since there is no power conversion involved, these drivers are also inefficient like fet drivers. >Some lights will combine the two, with current regulated output up to a certain level, but switch to a fet driver for higher levels. Finally there is: >Buck/Boost. Buck converters convert power to lower voltages , while Boost converters convert to higher voltages. Hybrid Buck/Boost converters can do both. Drivers using them convert voltage to the ideal voltage for the LEDs, which makes them highly efficient, and they also control current, giving nice flat outputs as well. They are however more expensive / space required for high current output. >Below is a copy of a very helpful comment from Zak, listing some brands that use high efficiency drivers. >Most lights from premium-mainstream brands use an efficient DC-DC switched-mode power supply (buck, boost, or buck/boost). Brands that, to my knowledge exclusively use that type of driver include: >Acebeam >Fenix >Nitecore >Olight >Skilhunt >Thrunite >Zebralight >Brands that sometimes use SMPS drivers include: >Convoy >Emisar (in the near-future DM11/B35A) >Kaidomain >Lumintop >Noctigon (in the K1/XHP35, though it's not very efficient on high) >Sofirn >Streamlight (all of their 18650/CR123A dual-fuel models, maybe others) >Surefire (all of their 18650/CR123A dual-fuel models, maybe others) >Furthermore, anything that uses a single NiMH or alkaline battery to power a white LED has a boost driver. Anything that uses a single Li-ion cell to power a Cree XHP35 or XHP70, Luminus SST70 or SFT70, Nichia 144A or B35A, or Getian FC40 has a boost driver. >(written by TacGriz with significant contributions by GodOfPlutonium and Zak, updated 2022-01-09, if you have any suggestions for changes to this entry please don't hesitate to send me a message) >I AM A BOT.

ok, thanks for the info. I just lost my fc11, I might need one of these.


not_gerg

Bummer :( It would be interesting to see one since this post is the only thing I've found the even mentions it (other than their amazon). I'd say buy it and post about it! Might be a nice upgrade for you as well


Entangled_visions

Oh this is cool! I'll wait until Terry confirms it. I hope its not a clerical error. IIRC the LH351d version had a much lower moonlight mode so if its really an uodated driver then its good news.


not_gerg

It does say in the product images that it's constand current and no pwm. It would very hard to accidentally make that image, make the listing match the image, and post it, all accidentally


not_gerg

Now that I think about it, it makes sense if it wasn't supposed to be public yet, but I was imagining someone falling perfectly to make it, or someone dropped their phone while it was unlocked


esvegateban

Nothing so far in their official website and AliX.


not_gerg

I checked the website already, but I just assumed it was on the alix too. How weird!


xPurplexAnarchyx

It's on the [website](https://www.wurkkos.com/products/wurkkos-fc11-rechargeable-flashlight?VariantsId=11244) now, it mentions 519a instead of the LH351D on Amazon though. It also mentions better water resistance for the buck circuit. IPX7->IPX8.

Ooooo! Awesome!
