FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

I know. Just planting the seed.

With regard to capacity, sure, it would be about half… That’s acceptable to me. … And they do make high-drain LiFePo4 cells (~20A continuous, 70A pulse)

As for boost drivers and such, I’m going to start a new thread and flesh this out some more. I have some ideas… I mean, I know it’s possible to do this cheaply given all the 1 x AA lights out there — though probably at a much reduced throughput (far less than 30W).

put me down for one please! :smiley:

The only reason 1 x AA boost drivers are so cheap is because they are for 1 x AA. We are just now getting some aftermarket boost drivers that are powerful - about 50w. They are still expensive, though. It might be many more months or 2020 before we get a range of sizes. So I would not hold my breath for a FW3A specific boost driver.

It will accept LiFePO4 cells no problem. The driver will not mind. You do need low voltage leds to go with it though, not the XP-L or LH351D. If you can manage fit SST-20 leds or Luxeon V’s, you are good to go. It will cost you output on turbo (that was insanely bright anyway) but the lower modes will work until the batterie is mostly drained.

It may also be a good idea to modify the low voltage threshold in the firmware, but otherwise… yeah. It should work fine with LiFePO4 if it has an appropriate emitter. For example, some color XP-E2 emitters have particularly low Vf.

I am interested !

^ had not thought about the low voltage threshhold, that will be very annoying if the value is not changed.

If only there was an option to have my FW3A made with those colours :heart_eyes:
Since its no longer “straight off the lathe” it’d be incredible to have a colourful option :innocent:

That rey light is a 100$ or something right? i prefer the cleaner look on the fw3a and since its under 40$ i dont complain.

Wasnt complaining just making chit chat, I think I mentioned it would be incredible to have an option and I didn’t say free :disguised_face:

iknow no problem, would be fun see such color options for those that want, probably advanced process coloring the light like that one.

All you need is a box of crayons :smiley:

or just leave in on the floor in a room that my misus is decorating :slight_smile:

The LH351D 90CRI actually has about the same forward voltage as the SST-20 actually.

My daughter is two so the crayons are HERS ONLY :person_facepalming:

I’ve been surfing the forum for a bit. This is my first post.

I just received, and love, the recent delivery of 2x BLF A6 (black/clear) from BG. Seeing this thread and the new knowledge I’ve gleaned from this forum, I have to get in on this GB! Put me down for one (XPL-HI), please. #1887

Heck, I’m still waiting for the slow canoe from China (FT shipper) that’s carrying my 2x Convoy S2+ (black/clear).

Happy to be here. I’ll post more soon (still in learn mode).

Welcome to BLF! Happy to see you here. :slight_smile:

You’ll be included in the next interest list update.

Always in learn mode. Learn mode is life.

Welcome to BLF Dougiestyle, enjoy your stay!! . :+1:

You can change the colour of Ti with voltage.
Some of the Rey pattern look like if they used a flexible PCB with a pattern, wraped it arround the tube and then applyed different voltages for different colors.
Or you have resistors on the flex PCB to get automatically the different voltages.
Maybe they work with one voltage for the body color and than they do the pattern.

Heat works also
Other Ti parts I see look if someone wraped a heated wire around it.

But this are only guesses.

Yeah, here’s a rough colour guide to voltage effect: (Borrowing TKs picture)
There’s instruction videos on how to do it.


Looks like the Dawn sections were submerged separately for a base colour then “painted”.
You can submerge the Ti or apply the electrodes to a painting implement and kinda paint different colours on, cool.

I did this light with heat:

But, we would need a titanium version for this of course :innocent:
