Very nice. Saving my pennies for this one.

Beautiful! :heart_eyes:

Looks good,what is the reflector diameter.

Please add SS bezel .

+1 (or make it optional)

Once again to confirm other information. It’s much appreciated if anyone could help optimize for better reading.

8. UI:
Tail switch to power on / cut off

Group 1 ( default )
When the light is on(the indicator on for 5s to show the battery power), press and hold the side switch, the brightness levels circle through low(50LM)-Med1(300LM)-Med2(1000LM)-High(3000LM), double click to Turbo(5000+LM), when encounter the brightness you need, release the side switch.

When on Standby, click the tail switch to cut off (indicator is off ), click tail switch again back to Standby, click side switch to turn on the main led. When the main led is on and you click the tail switch to cut off, click tail switch back on goes to the remembered brightness levels.

Group2 (Ramping)
When the light is on, long press to ramp, 2LM-5000+LM(150 levels, ramp from lowest to highest in 3 seconds, blink to remind reaching lowest or highest). Ramp again within 1.5s, reverse direction. Ramp again after 1.5s, keep the direction(same as Q8). Click to turn off the main led (Standby)

When the light is on or on Standby,double click to Turbo(5000+LM), click back to previous brightness or Standby.
When on Standby, long press(1s) to Moonlight(2LM), click back to Standby.

2.When in Standby, the led is Green as locator in the dark. Click tail switch to cut off.

Looks good… :+1:

Please strongly consider doing what ZozzV6 suggested. Quoted below.

Leave as much metal internally as possible to facilitate proper heat sinking & beat transfer.

There is no reason not to do this. :slight_smile:

.

I was expecting a 20mm mcpcb which pretty standard and found in the L6. Are you using a 32mm Maxtoch Copper Direct-Thermal-Path mcpcb?
Using a bigger mcpcb is good for spreading the heat, but I just want to make sure it easy for us to swap to different emitters. The Maxtoch mcpcb is carried by Mountain Electronics and available on Aliexpress and other places. So if that’s the one your using, that will be good.

Is the tactical ring still threaded? I assume it will also come with a smooth ring to put in its place?

One tip I can give is to add some notches around the side switch hole so the switch pcb can be installed/removed easily without have to desolder the wires. Like this:

I wasn’t expecting a 2 piece head. It reminds me a lot of the S70 design. I guess that keeps the cost down.

I’m personally ok with the body-matched aluminum bezel as some might prefer that aesthetically, but a stainless steel bezel add-on option would be nice.

Would prefer the default is Group 2 (Ramping), but that’s just nitpicking and not a big deal.

Has Sofirn settled on a price?

The downside to leaving extra material is the weight. This can make the head too heavy and the light imbalanced. It also increases the shipping costs.

Although the current design is not ideal, it looks “adequate” to me.

They have a a really good goal price for the group buy, but I will need to see if all their current design changes and projected shipping costs still allow for it. So it will probably be announced a bit later.

The UI sound good to me.

Leaving that amount of metal is not going to significantly increase the weight.

But it will significantly increase the heat sinking & heat transfer ability of the light.

Leave the metal where it can be left.

They make it very easy to switch groups. It’s not complicated like Narsil where you need instructions to make sense of the menu.

In stock form the heat needs to travel through three very thin sections making the fins useless near the bezel. Even with an L6 and S70S most of the heat dissipated at the side switch area. It need a good path to send heat to the front.

Is the switch mounted directly to the driver?

I’m glad they are using a SMO reflector. If anyone wants to add a bit of texture, I think Old Lumens had a technique of spraying clear paint on the reflector. It’s definitely easier to add texture than to remove it, as in making an OP into a SMO. That’s almost impossible.

Does the tail switch always turn on to standby?

I’m not sure if a 4 click electronic lockout is needed since you can use the tail switch for a mechanical lockout, but no big deal.

All the rest seems good to me.

It shouldn’t be.

It just looks like there is no support under the switch which means it must be mounted to the driver.
