Lot of people can’t do proper dedoming like some of skill moder here it is hit or miss (that mean some new LED cost),factory done may add some cost but surely less than larger the head for the same throw effect.

BLF Bruiser. Wink

I would prefer a better programmable UI with a single side switch. Or give me two side switches – something like the interface that Nitecore used on the EC. A mid-amp charger port would be nice, too. A tail switch is of no use to me.

I’m not too concerned about the size. I am looking for about $50 delivered for the price. Think Astrolux MF02 with some attitude, two batteries and none of the wrinkles.

I wanted this to be a sort of toolbox light; big enough to give long run times and have a good, high lux, balanced beam for work and outdoors. I had hoped that the BLF GT would fill that role. I was wrong.

With BLF lights I would dream a little bit bigger than a sort of a toolbox light. My proposal would be a BLF alternative to any of these large models: Acebeam K65, Thrunite TN40S, Fenix TK75. All come with great output and throw.

Will keep an eye out on this project. My Thrunite TN31 LED swap mini project (swap to XP-L HI or HD) is definitely taking a way-back seat now….

I’ve got a thrower, a flooder, and an EDC too. Still looking for a bigger thrower, flooder, and a new EDC, give or take a few. I’m a flashaholic.

I understand what you are saying. Thumbs Up . BUT…… you are assuming some factory worker, who may have never dedomed anything; can do it with the skill & accuracy of a seasoned modder.

That “assumption” could well be a recipe for disaster in this, or any group buy. Unless a “factory” has proven they can dedome properly this should not even be a consideration.

The same thing is going on in the GT70 Group Buy. A dedomed emitter ‘may be an option*….. (may be an *option)…… BUT only if Lumintop can prove to TA that they can dedome properly.

As was said earlier… if someone wants this light dedomed they should do it themselves or send it to a skilled modder to have it done.

I pitched them the idea of using NarsilM or Anduril, because that is what I prefer, but they seem to want to make their own UI. I believe the BLF drivers that use NarsilM are quite a bit more expensive to manufacture due to the premium parts, etc… This would in turn raise the selling price which no one wants. Hopefully the factory driver and new UI we are working on will be just fine for the vast majority of buyers. It should be wayyy better than what you’ll get in the S70s and L6.

I think having two sides switches would overly complicate things, plus it’s not really necessary.

Built-in charging is a no-go due to the batteries being in series. The only safe way to do it would be for Sofirn to use a battery pack. I’m sure nobody wants a battery pack.

Nobody has to actually use the tail switch if they don’t want to. It would just be an easy way to cut all power for when the light is being stored or transported. It’s also good for modders who are going to swap the driver out. Using a flat tail cap might reduce the overall length by about three quarters of an inch. It’s possible they may offer a flat tail cap later.

Here are two of VOB’s videos on slicing the dome. I did this myself, it’s not too hard. If you can solder the 2 wires and have a sharp razor blade, you can do it. You might not even need to do the soldering part.

I also support the idea, that the dedoming should be at own risk. Besides that, check any video on Acebeams K65 that comes with factory dedomed XHP70.2. Seems the dedoming resulted in piss-poor yelowish or pukey-green tint.

And the 70.2 doesn’t need anymore help with it’s beam being ugly as it is.

Thats why i also suggeted a BLF multi led design with XHP35HIs. There would be the petal spill, but hotspot and tint should be much better.

Or, you can have a 3rd party dealer do it for 80bux/hr and then bill Sofirn for 3× as many units as were actually sold.

Okay guys, I am convinced. Dedoming is really a personal responsibility. And the resulting tint is currently almost totally undocumented for the LEDs.

I just wonder, that how can Acebeam achieve dedoming results with acceptable failure rate.

Keeping this flashlight budget friendly will not mean, that these experiments would be affordable.

AWESOME IDEA!!

It seems like this project is going to be a L6/S70 style light. (Which is great!)

I’m hoping that in the near future, Sofirn (or some other manufacturer) will realize that there is significant interest in a triple LED 26650 light.

Cheers!

I think, your thoughts about the UI are much preferable.

I would just add these:
- I’d prefer mode group selecting as 6 fast clicks, long click in Group 2 might result unintended mode group setting change
There is no chance of that because the light has to be in the off position.
adam7027 wrote:

- in Group 1, after activating strobe, press and hold could loop additional special modes (1 change per completed 1 second while holding the press, just like changing normal output levels), as someone here voted for additional special modes – I think, that would not be a bad idea, if they are hidden enough
(fast strobe /10Hz or 18Hz/ would be the entry point, followed by SOS signal, 0.5Hz (once per 2s) beacon and 0.2Hz (once per 5s) beacon)
- I’d chose triple click in Group 2 to enter to/exit from momentary on/off mode with the last used output setting. That would be sort of awesome, I think Wink

We will have to see if Sofirn has room for any extra blinky modes which can be put off to the side and hidden. At this point, it’s a matter of getting the basics right. After that, maybe things can be added.

How many people would love to have extra blinky modes like Beacon, SOS, Strobe? I think it could be made. But how do we hide them? Double click to Turbe(click to go back), another double click to SOS(click back to Turbo), another double click to Beacon1(click back to Turbo), another double click to Beacon2(click back to Turbo), make double click to cycle through Tubo-SOS-Beacon1-Beacon2-Strobe, something like that? Any ideas?

As a fisherman i don’t actually think tints plays a big part in fog? I know we all have our own views on this but for me a NW tint doesn’t help. My house is rarely foggy but we do get heaps of sea spray and mist and that is a pain to get thru. I think the cold white tints do create more glare in fog but still work just as good as a NW tint. Even at my girlfriends parents place on the lake its always got heavy fog but i still get better throw from a cold white tint.
I have noticed heaps of people live inland on BLF and use there lights in different situations to me which could cause different results. I only use my lights around water/coastal areas.

Thanks for the feedback Jason on your light maybe we can highlight the information so people can reference it for throw numbers.

I personally don’t need 1km of throw in this light i would prefer a more linear beam with good width. Id be happy with the stock reflector size in the SMO variant. People now have heaps of options of XHP70 throwers on the market that they can buy right now so throw isn’t much of an issue.

I dont think we will get any where near 270KCD (1km throw) unless the dome is sliced and the light is running DD.

As for the SP70 itself

  • Custom driver maybe 9+amps or DD ( No amperage numbers indicated as of yet)
  • Two 26650 in series
  • 90mm head diameter
  • SMO reflector
  • Dual switches rear clicky and side switch
  • XHP70.2
  • Multi mode UI with ramping and a second group set with standard modes (e.g low, medium, high)

I think Sofirn is in charge of this thread? But are we going to use the numbers from the K70 build as people in or start a new group buy?

We never did a group buy before. Help will be much appreciated.

It would be great if people who get in K70 group buy come to this one. More people get in, lower cost it would be, then we can see if we can offer better price.

Furthermore, we are not quite sure if it’s a BLF SP70 or Sofirn SP70. Both works fine for us. If you guys want BLF SP70 or name it other way, anyone can make a logo for it? Is it necessary?

Personally, I can live a long, happy, & fulfilled life without the ‘blinky modes’. But if they can be added without taking away from the more important ‘good stuff’ JasonWW mentioned earlier…. why not. Just find a way to hide them away. Wink

As far as a name & logo. Why not have both Sofirn & BLF names on it along with SP70.
There are several talented people here that have the capability to create this.

It does not have to be gaudy nor complicated. Simple & elegant will do just fine.

What your describing above has my head spinning. Lol. It sounds really complicated.

I would leave double clicks only for turbo.

Is this possible: Triple click for Strobe, then you press and hold to cycle through the other flashing modes. Then click once to either go back or turn off.

I think this would work in both groups and it’s pretty easy to remember. It functions the same way as you change brightness levels, but you have to triple click first.

I think it would be well hidden. If you don’t like blinky modes, never triple click and you will be fine.

If these would be implemented, I think, blinky modes should only accessible in Group 1 (set of output levels) by fast triple clicking. Looping through blinkies then should be done exactly the same way of looping through set of output levels. Then, if we would want to exit blinky mode set, fast triple click again single short click. This would practically hide blinkies for those, who do not prefer them.

In Group 2 (ramping), these blinkies should not be available then, at all. In Group 2, fast triple click could enter the flashlight to momentary on/off (emitting light while switch button is pressed) - and fast triple click again switch the flashlight off and on to return normal ramping operation (forgot, that fast triple click here could be a desired signal here).

Again, for the cost efficiency of the driver (prioritizing stable basic operation), I don't insist on asking for these modes to be implemented. These are considered not really useful for the majority of people, but a few groups of people actually would happily use these (I think, users of these functions are somewhat under-represented here).

Edit: i didn't notice, that JasonWW already answered Smile

And I think, even if these are chosen to be implemented, could be postponed to the time after the first version of this lights reaches production stage - for the first version, the UI JasonWW described originally without the blinky modes, sounds pretty sufficient to me. But again, it is not me to decide Smile

Okay cool we are here to help Big Smile

Once we get some idea of the specs we will start a new thread for a group buy.

As for price we will aim to please all! Make us an offer and we can discuss it in the group.
Say you want us to move 500-1000+ lights for this group buy make an offer based on the specs and that amount of sales that are expected? Plus any additional parts we can work out a new price if needed.

You may have to send a prototype to a BLF member to check if its okay and up to standard not sure where that falls with cost (who pays)?

Also will you be selling the light through a 3rd party vendor or your aliexpress store?

Will you stock spare parts? Is it possible to make an OP style reflector that will fit if we get enough interest?

As for the name we can have a discussion here in the thread. I like the BLF70 maybe even BLF70SP i am not that creative so some one else will have a better idea.

Also i am with every one if we have a hidden strobe it should be a triple click to access from the standard group set.

Now i will see what every one else in the thread thinks? Does this sound okay lads?

I don’t know if the BLF name can be put on any light. Especially one that does not use a BLF based driver. It may also be up to the forum owner, SB, since he owns the BLF name.

Personally I think Sofirn SP70 is a fine name. I’ll contact SB to see what he thinks. Texas_Ace as well. There might be some sort of prerequisite to use the BLF name. I don’t know for sure.

My Convoy L6 thread with XHP70.2, Texas Avenger FET driver, Narsil v1.2 ramping firmware (old), lighted side switch and cut down SMO reflector. Lots of amp draws on stock driver as well. 

My Supfire L5-S thread with XHP70.2, 26350 cells (4,100 lumen!), Texas Avenger FET driver, NarsilM v1.0 ramping firmware and lighted side switch. My mini L6! 

Modded S70S with MTN FET driver, RampingIOS (D4) and lighted side switch.

You can use the BLF name for BLF modded lights look at the older BLF group buys? This is actually a scratch built BLF light lots of BLF lights have used of the shelf parts including divers. For example the Luckysun BLF D80? All as we done was changed the LED to a DTP MCPCB and up the amperage of the stock driver.
