Andúril 2 coming to Sofirn - The general Sofirn development thread

sofirn tried SST20, LH351D and XPL. The beam of XPL is the best, so it’s the first. Other versions are possible but need to make it step by step.

SP32A V3 XPL HI, 21700, No glue, no timer step down.

Seems easier said than done,

Eg, make the button flush or even recessed to prevent accidental activations… “It’s hard to find the switch by feel!!”.

Make the switch protrude for easier activation by feel… “My light turns itself on in my pocket all the time!!”.

Make the switch stiffer… “It’s too hard to press!!”.

And back and forth, back and forth…

This is a preposal? A 21700 sized tube light?

FW3A is good enough, does BLF still need a compact 21700 light?

Larry’s preposal is completely different from the FW3A.

As far as I know, nobody makes a light like Larry’s proposal. I think one company makes something similar but it’s over $70 which makes it cost prohibitive to use as a host.

I think FW3A is different. It uses 18650 cells instead of 21700 cells. It uses a Carclo 105xx optic whereas Sofirn normally uses reflectors. My cost-effective suggestion for Sofirn would be following:

  • Use the 21700 tube of C8F as a standard part for new 21700 flashlights
  • Adapt SP32A V2.0 and SP31 V2.0 head to the C8F 21700 tube and tailcap (one with tailswitch, one without)
  • Use the high current tailswitch of the C8F 21700 (> 10A, 125V), like this one: https://www.aliexpress.com/store/product/Special-flashlight-switch-125V-10A-forward-switch/330416_32328815036.html
  • Offer a host version without „angled board“ (switch not soldered to driver) and with standard sizes (20mm/22mm diameter for drivers, LED boards)....it will sell like hot cakes for sure!
  • Offer more emitter choices and tints, i.e. SST-20 5.000K 70CRI, SST-20 4.000K 95CRI, XP-L2 4.000K 90CRI, LH351D 4.000K 90CRI and 5.000K 70CRI...

My extended wishlist...

  • In terms of Andúril there might be a chance to upgrade the e-switch models, i.e.:

SP31 V3.0 21700 (XP-L HI, SST-20), incl. kit-version with Sofirn 21700 4.000mAh battery (Lishen LS2170SA)

SP32A V3.0 21700 (XP-L2, LH351D), incl. kit-version with Sofirn 21700 4.000mAh battery (Lishen LS2170SA)

SP33 V3.0 26650 (XHP50.2, XHP70.2, MT-G2), incl. kit-version with Sofirn 26650 5.500mAh high capacity battery

SP70 BLF edition (XHP70.2, SMO reflector, Andúril adapted to work with e-switch AND tailswitch without revoking the ability to use momentary and mode memory)

  • SC31 could be kept "as is" but please exchange XP-G3 by SST-20 for a better tint and more throw.
  • SP36 is fine but please take spring bypasses (~ 800lm - 1.000lm on top) and flat head screws in the bottom PCB into consideration to improve the current path.
  • Q8 is fine but please offer SST-40 5.000K and Luxeon V 4.000K 70CRI as alternatives. Neven (www.led4power.com) has the right boards available.

This is probably one of my biggest wish items - some good options between 4000 and 5000K, and some high CRI. Cool white is just….blahhhhhhhh.

I would imagine another compact, but powerful light would be a great success. Emisar D4, D4S and the Fireflies E07 have been very popular.

SST-20 is a cheap alternative to XP-L HI with even better throw. For SP31 V2.0 it will be a win win situation, causing less prime costs for Sofirn while they can still maintain a very competitive price. Now that Sofirn was able to source LH351D they may want to try this LED as an alternative to XP-L2. Again, possibly lower prime costs and a better tint in return.

Agreed :slight_smile: Just wish Luminus would make a 5000k high-CRI.

E21A and Optisolis only work on Virence.com mcpcbs. The SF14 was a perfect host, which was very easy to swap in these board/emitters, but unfortunately SF14v2 is not.

It happened.

Thank you! I took the liberty to post another link as yours does not work unfortunately.

Happened what? Another bulky dumb H03 replica?

Well it does have an 18350 tube but I agree with your points otherwise. lol

Also I find it hard to compete with the EE X1R w/choice of color and LED tint, proven moddable, and on a deal at $16 - I got 3, 1 in each color :facepalm:

didn’t you have to mill out your X1R? That isn’t too mod friendly for most of us :slight_smile:

Should have said "moddable for me" -- only used a rotary tool and wasn't really difficult or time consuming much. All done by hand, free style. There's a lot of mods posted I can't get even close to accomplishing, most of which are mechanical, needing a milling machine, lathe, or way better hand tool skills than I have.

For the X1R, the cutting away of materials didn't have to be done precisely - just had to make room for a driver mount.

Even before Dale got a lathe, he was doin things with hand tools that were amaz'n that I still can't do.

Except the money from this one goes to Sofirn. :smiley:

I don’t think the H03 has built in charging. Plus I don’t like that the H03 and X1R both have single click on and press/hold for off. That’s so irritating to me.
