Who knows how to get in contact with Nightwatch (the flashlight brand)? My Taobao chat tool does not work currently. I would have a few questions about the NSX4.

Other manufacturers have an Aliexpress store or even a BLF account where you can bother them with questions. Wink With Nightwatch I never found any other possibility to contact them apart from their Taobao store.

I dont know, but I do know Neal works with them a lot. You might ask him how to best contact Nightwatch.

What’s the current highest output LED?

Still the XHP70.2?

I know the SBT90.2 is a nice competitor but only because it’s a 3v led instead of a 6v led like the XHP70.2.
The latter one has still a higher (potential) output.

Using a 6v led isn’t a problem, only need to find a suitable driver for it to drive it with some decent amps. Somewhere around 8 or 10A.

Still need to figure out the cell configuration. Right now I was thinking to use 2s high drain 18650’s. Though might change it to 21700’s, however that would require some major redesign.

Cree CXB3590 will do about 16,000 lumen. Its 36v so you need a boost driver and a 12v source. The one driver I know of uses a rotary knob instead of a button. So not very practical.

As far as “regular” leds it’s the 70.2 as it can be driven at around 20 amps at 6v (over 6,000 lumen). At only 8 to 10 amp it is around the same output as the 90.2 when it is pushed hard, about 5000-5300 or so.

Newbie here, with my first of (likely) many stupid questions. I’m close to pulling the trigger on an Anduril UI driven light, but I’m excited for many of the muggle-friendly features discussed in ToyKeeper’s Anduril (Rev 2) update. When Anduril Rev 2 is released, will there be an easy way to update current Anduril UI with the new operating system? Thanks!

There is no easy way. You’ll need to reprogram the MCU. Some lights need a clip and some use pins to make the contact. Some lights need to have the driver removed, some don’t.

Can a 3.5×3.5mm led be flow soldered onto a 3.0×3.0mm board?

Looks like Kaidomain has copper dtp mcpcbs for 3.0mm leds in 14mm diameter. http://kaidomain.com/S028906-14mm-Osram-3030-LED-Copper-PCB-2pcs?page=4

Another question I could have is..
What options are there for a dtp 14mm mcpcb?

Thanks in advance.

3535 boards are extremely common – though 14mm is an unusual size.

I know some 4040 LEDs have been reflowed on 3535 but it is very challenging and probably reduces performance. If I couldn’t find 14mm 3535, I’d file down a 16mm.

What happens if you stack an extra 7135 on a fet +1 driver? Would it matter if its the BLF A6 fet +1 driver vs the Mtn fet +1? Is it as simple as, low mode is now ~700ma instead of 350? or something else? Would different firmware change the result of doing this?
What about if you soldered on a slave board of 5 or 10 7135’s instead of just stacking one? Same result, low mode is now whatever the 7135’s put out?

Sorry Jason, never thanked you for your reaction.

Those COB’s are indeed very high output in a single package. That driver does sound interesting, do you mind sharing that driver?

Though I was talking about the ‘regular’ leds. So the 70.2 is still king of the leds when looking at raw power.
After some driver search I think it’s better to go to 12 A. It gives a nice boost in output and would still be doable.

Unfortunately my power supply only goes to 5 A so cant test the setup at those power levels..

You basically have the right idea. The 7135 channel outputs a PWM signal designed to produce a certain brightness within this range of 0.35A. Do keep in mind that it will screw up the brightness ramp. Like the Low mode may now be as bright as the Med mode. So what used to be Low Med High may now be closer to Med Med High. You’d need to change the firmware to get the brightness ramp back to being smooth. This is why no one really stacks 7135 chips on FET+1 drivers.

The whole point of the extra 7135 channel is just to get a lower moonlight level. A single FET can do the whole range of brightness, but moonlight is a struggle to be dim enough.

Could anyone recommend me a new light to get?
I’m looking for a single cell 18650/21700/26650 flooder with a decent amount of throw too maybe like +300m which shouldnt be hard to get with enough lumens, but anyway ramping UI is a big plus so those are preferred. Not so interested on max turbo, but constant amount of lumens, the higher the better. What are my options? I already have Astrolux MF01 Mini so that is out of question.

Also other questions: FW3x or FW4x? Both seems nice, other gives more lumens on turbo, but what about other stuff like regulation etc? Is there any glow gaskets for FW4x or any other “special” parts, because there seems to be plenty for FW3x? This light would be mainly for modding with aftermarket parts and using it as EDC light, but hard to choose because new models and different designs. Also if you can recommend something similiar or even better that would be nice. KR4 maybe?

If you're considering the FW3x or FW4x, how about the FW21 Pro?

It's way brighter and maybe it throws further?

The only thing stopping me from ordering it is the fact that it only comes in cool white right now.

Its nice, but head size is a little bit too big for my EDC use.

Yeah, I wonder if it'll fit in my pocket, but I plan to order it anyway as long as it were to come in a warmer tint.

I would consider the Sofirn SP33 v3 3500lm. It has a ramping mode, 5000K or 6500K, usb charging, is bright, decent throw, good size hotspot, 26650 size gives long runtime and handles heat well. Budget friendly price.

The ’33 is a nice light (all of the above), but again being Mr Glass Half-Empty, if you get a “decent flooder” and crank up the lemons to try seeing far, your immediate foreground will be stoopit-bright and wash out anything the hotspot could reach. And a throwier light without blinding spill won’t be a good flooder, kinda by definition.

I keep beating this dead horse, but nothing beats 2 lights, one flooder and one thrower.

Best might be a zoomie like a Z1. Then you kinda get the best of both worlds(?).

Yeah I’m kinda balancing between flood/throw and looking something nice between. I like SP36 BLF’s beam pattern, but I wish something a bit more floody, but a little bit more throwier than MF01 Mini. Zoomie could be a good option, never had those except some terrible free one that I got when purchasing fireworks some years ago. Didnt you win one zoomie from GAW a little bit while ago? How was it and what was it?

Maybe three lights. Headlamp and dual wielding. With my thrower I shall pierce and with my flooder I shall flood. Big Smile

Hmm SP33 seems nice. Is there any Conwoy substitute even though Sofirn is good too. What about EC03 vs. SP33? 5000k and usb charging is a big plus too and almost mandatory.

2 lights are good, but my 2 are the SP33 and SP70. Little and big. Lol. There is no one light that does it all. Maybe those dual pattern lights that have flood patterns and a seperate single reflector for throw, but they are usually big and expensive.
Acebeam x10, Fenix LR40R, Ledlenser has their focus technology, etc…

“Between” is almost always a compromise that tries to do both but does neither very well.

Even just going outside for a few minutes, I’ll take my E03 with diffusion film as a flooder, and ‘micro if I want throw. Anything else is one of those lousy compromises.

I’m in the same boat. I was very tempted… but I’d like to see it offered with other emitters. I don’t need 10k lumens on turbo, especially since it doesn’t last but a handful of seconds.

Yeah thats must been one of the reasons I dont have any light that tries to do both. I think I could go for a dual cell setup like Fenix LR35R, but for that price I require different tint.

What about Sofirn C8F vs. SP33 V3.0? Maybe getting SP33, just because I dont have any XHP50 led light yet. Decision is hard though. EC03 seems nice though, maybe waiting for a warmer tint. Multiemitter would have better flood, but no hotspot so choices, choices.

The multi-emmiter light is just like a reflector light, just with 3 small reflectors instead of a single bigger one. So you do have a hotspot. It’s a smaller reflector so the hotspot is bigger.

The only reason it’s flood would be better is that it’s brighter. I don’t think there would be a big difference in the angle the light comes out.

You can see a similar comparison here with the EC01 and EC03. The EC03 has a bigger hotspot and is brighter. This makes its spill light brighter as well.

Well yeah there is hotspot, but that aint as bright spot, but more “softer” compared to single emitter lights if I’m correct? Unless reflector is really wide, OP etc?

EC03 with green body color and 5000k tint would be ideal at this point though. Too bad there isnt one yet, not sure even if they are getting it green makeover.

What if I decide to go “full flooder” with single or dual cell setup? Like I said I got SP36 BLF 5000k and MF01 Mini 4000k and I like them both a lot. Maybe SP36 goes a bit between flooder/thrower , but I would like to get some more flood without than much of a visible hotspot. I just dont want to buy “same” (almost same lumens, almost same beam pattern etc.) light twice. Lets go full crazy and lets forget how many cells it should use, if there is some real improvement of sustainable light. Maybe even 4×18650, but much preferable 3xcells even 21700 goes.

EDIT: Made a new thread about this: http://budgetlightforum.com/node/73723
All suggestions are welcome, thanks!

Did you get something unsolicited in the mail from China? Maybe unidentified seeds or other junk?

Searched pretty well and coudn’t find this question asked yet:

Whats the purpose of frosting the center of a 3-up or 4-up optic? How does it affect the beam?
