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.
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.
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.:
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.
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.
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.
