Andúril 2 coming to Sofirn - The general Sofirn development thread

I think Sofirn should find a way to make accidental activation harder on the SP10, it’s a good light but I don’t EDC mine often because it turns on too easily in my pocket, or maybe I should just unscrew the tailcap a bit… but still I think making accidental activation a bit harder would improve the quality as product.

I’ve been looking for an AA/14500 light and if this one is updated to a really nice emitter and with Anduril, I’d get one for sure.

Good point about the accidental activation. A couple of my Sofirn 18650 lights with side switches have turned on by accident.

I hope Sofirn will offer buyers SP40 a choice between emitters XP-L and LH351D. And also the choice of CCT 3000K-5000K.

The SF14 v2 is more difficult to get to the mcpcb unlike the SF14 original where you just twist off the head/bezel. Also the original SF14 fits the more typical 16mm mcpcb so I can use the Optisolis and E21A 9080 emitters, which is perfect for 14500 and AA flashlights. The SF14 v2 however fits I think 14mm mcpcb only.

If you need 14mm but not dtp, try

for 219s and the like.

They got 12s, 10s, even 8s.

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?
