Sofirn SP70 Alone $50, PM for AMZ US CODE(LIMITED)

I don’t see any issue with using BLF in the name seeing as the light is being made for us by us its still a BLF build. As for the driver its better for them to make the driver its good inventive for them. For us its less time consuming and won’t take as long to build the light and will keep cost down. Maybe we can use BLF firmware on there driver but the original modes already sound good.

Look at the Astrolux A01 that is a BLF edition light. In the end it doesn’t really matter but if we are going to have major input its a loss to not have our name on it.

The only time we have ever had an issue was after the first BLF A6 driver where made. We had companies trying to place BLF naming on random lights because they saw how big the group buy was.

/\ … :+1: … Agreed.

Wellp, “FUBU” is already taken, so… :smiley:

Thanks @Sofirn for stepping up on this project, I think it’ll be a big success for your company and for BLF consumers.

Also thanks @Sofirn for asking about using the BLF name.

Thanks @JasonWW too for the input. I agree that Sofirn SP70 sounds like a good name. Since I assume that the actual design and engineering will be handled in-house by Sofirn, they deserve the credit. Of course, if that changes, or if they decide to use a BLF driver, or if some BLF member(s) have a significant level of participation in the actual design/engineering, we can re-evaluate the name.

I would of course appreciate it if you mention somewhere in the final product description that it was developed with input from BLF members.

I would definitely prefer well hidden blinky modes. I frequently use strobe mode to discourage lurkers in a dark corner of my back yard. As for the UI, I think I would like:

  • Double-click to Turbo
    • Double-click to Strobe
      • Single-click to Beacon1
      • Single-click to Beacon2
      • Single-click to SOS
  • Double-click back to Turbo

That is the whole plan we build the light the way we want it. They will design the light to our specs giving us a choice of parts and design from our feedback in the thread.

I understand. So let’s just hold off on deciding the final product name until we have the final specs nailed down. For now SP70 is good enough for internal discussion.

I’m surprised you don’t like the triple click for strobe. You can get to it faster and simpler. Maybe you think it’s too easy to accidentally activate? If so, maybe it can be changed to 4 fast clicks. Then if you try to activate Turbo and press one extra time by mistake, it will just do nothing instead of surprising you with strobe.

One of the good things about my suggestion was that dbl clk is always turbo and nothing else. Also, a single click is always either on/off or back to the previous level. Nothing else.

Plus it seems natural to cycle through the blinky modes the same way you cycle through the brightness modes. This just makes sense to me.

That works too. :+1: As long as blinky modes are available but well hidden I’m all for it.

Yea sounds good

Compared to existing lights of this style (L6 and S70), is it possible to design the head with thicker internal shelf and additional/larger fins for better heat dissipation?

The L6 shelf already looks to be about 6mm thick and can already handle 120 watts. How much thicker does it need to be?

In looking at the L6 cutaway, I can see that if there is a triple emitter version built later on, the shelf is going to be much higher. This would be a great opportunity to use the same basic outer fin design as the single emitter except cut the fins under the shelf much deeper into the head. You will have much more surface area then.

Both single and triple versions would look very similar until you hold them sideways and notice the different fin depths. Does that make sense? I might try and draw a picture tonight.

BTW, the SP70 will use a clear rubber side switch boot like the Q8 to make the switch leds easy to see in the dark and identify the color.

So basically you want Narsil lol

I think he is talking about the very thin walls along the edge of the reflector.

I pointed this out way back when the L6 was still in the prototype stage but it was never addressed. It would significantly improve heat dissipation if we gave the heat a path to use the fins along the top of the light.

As I am sure you know the heat is kind stuck around the shelf area of the light and has a hard time moving higher up the head to use all the fins.

See the Red area below:

Yeah basically, i’d prefer narsil as well
And then it could be the Sofirn SP70 BLF edition

:smiley: Yeah, I’m not claiming originality, I’m sure I ripped that off from somewhere.

Also @Sofirn and everybody else, would it still feasible to include some of those little silicone rings to use 18650 cells instead of 26650? I suspect I’m not the only one that has an extensive assortment of 18650 cells but only about one or two 26650s cells.

This seems to be a nobrainer and should definitely be included IMO. :+1:
Thanks for mentioning it Caleb & thanks TA for explaining it. :beer:

Good discussion.

Unless the design and CNC programing has already been finalized, anything we do to increase heat dissipation without significantly increasing cost is a good thing.

Don’t we all just want to be able to blast as much light as possible for as long as safely possible before stepping down?

My stock L6 gets too hot to be comfortable to hold in a relatively short time. If we’re bumping up the output significantly without making a way for the heat to be released, this will just exacerbate the issue.

This is already NOT a small light. Let’s not be afraid to add a few extra ounces of aluminum that could make a difference in performance.

I’ll let the engineers work out the specifics.

If you want I have an stock domed XHP70.2 Astrolux MF02 with TA driver and Andúril. 84mm head and 71mm reflector. I can set andúril ramping max to a specified lumen output and measure intensity and throw. That way we can estimate what we can get with the SP70.

I have an L6 XHP70.2 and it suffer heat transfer to upper fins. The hottest part around the side switch.

For firmware I really want Andúril but I’m ok with Narsil too :smiley:

:+1: larger and if possible deeper.

Trustfire does some extreme finning in some lights, like this one:
