The general Sofirn development thread

Hi there,

 

In the SP70 thread Barry just spread the good news that Sofirn currently checks if alternative/new versions of their current flashlights will be feasible, depending on actual demand, see quote below.

I think Sofirn is okay with using just the one 5350K-5700K tint for the SP70, but if they want to do 2 different tints that's okay by me. Assuming that I understand what you mean. Are you maybe talking about other models besides the SP70?
I'm talking about other models. Some want Sofirn Q8 with 4000K tints, or C8F (21700) with one emitter etc.

 

Thus, I thought it might be better to start a new thread here to discuss it and to avoid further distraction from the development-thread of the SP70.

My thoughts about these plans would be:

Hi Barry, that's great news indeed. If I got you right the making of these alternative/new versions depend on the actual demand. So, do you plan to run a poll here on BLF to gather as much information as possible? AFAIK, Neven ("Led4Power") offers a ready-to-use MCPCB with 4x Luxeon V 4.000K 70CRI for the Q8. However, it still takes some modifications on the Q8 to install it. In terms of a more floody, less bright but HighCRI beam I could imagine that Samsung's LH351D 4.000K 90CRI would be fine. For an ultimate multi-emitter thrower the Osram KW CSLPM1.TG might be worth looking at. With 4 of these installed and correctly aligned there's a chance of 5,000 lumens (i.e. 4x 1,250lm @ 5A) with an extreme intense spot and great throw. Unfortunately, the Osram LED requires a current-limited driver and won't perform well with an FET.

Concerning the C8F 21700 with single emitter:

Great idea. Alternatively, I would greatly appreciate it if Sofirn's C8S host gets an update for 21700 batteries. It's a nice host for it can use 20mm drivers out of the box. Smile

@Sofirn: You should notice that the most favorite emitter color in BLF is Neutralwhite/warmwhite or between 4000K and 5000K.

You could sell more Sofirn Q8 with a warmer emitter color too.

I would love to see popular flashlights with 4000K Color.

I would like to see single emitter C8F 21700 with bigger head for throw and what about SP70 with XHP35? Wink

As it is just a suggestion, I thought, I just go here from the SP70 topic – because this is not related to the current SP70 specification set (yet).

I would like to +1 for Satan@103TFS, as if Sofirn makes SMO reflector for SP70, there should be definitely XHP35 HI options (e.g. a set of 5700K, 4500K, 3500K CCT) – and there should be at least one high CRI option (e.g. 4500K 80 or 90CRI).

And for the ‘C8’-ish flashlighs, let us ‘gauge’ the single cell compact throwers (now all with 21700 battery tube), so there could be C11 with a net reflector diameter of 55 mm (as C8 is ~40 mm), and there could be a C14 with 70mm diameter for extremists. Also, I could imagine a C14F as well Evil

It’s pretty cool to see a company expressing interest in pleasing the customer. I hope this thread inspires all sorts of new lights and options.

For me it would be nice flashlight with a SP70 head and 4 xp-l hi and a tube for one 26650 with a fet driver. Such tm16gt only more compact with a better price and probably stronger

My wish would be for Sofirn to stop gluing their lights together, so it would make life easier for users to perform their own mods in cases where it’s not feasible for Sofirn to produce alternative versions for sale.

Good thread.

Would love to see a larger head single emitter version of the 21700 C8F with Oslon KW CSLPM1.TG, KW CSPLM1.TG, or KW CULPM1.TG and USB C recharge. Sofirn should pay attention to how extremely popular the Emisar D1S and GT Mini is. This single emitter C8F with easily 400+kcd will be the farthest throwing production flashlight in existence for its size category and will sell very well.

+1 Thumbs Up

It only takes an appropriate centering ring (Hoop is gonna make some of them for several flashlights soon…I can’t wait to get them) and a current-limited driver that makes sure the LED will not get more than 4.5 – 5.5 amps (e.g. Neven’s LD-A4 driver). Love

Hold on people, Sofirn takes things slowly ,at least that’s what it seems. I believe,the right thing for sofirn to asure sales is to check out the interest of the details on3 the3 customers ,like : wich one3 would you choose first : orange peel or3 smooth etc.,not to many makers do such thing,and in a tight market that so many manufacture nice budget flashlights,might be a good option to start in blf,as so many other reviews would come out for a good quality flashlight.
USB type c charger included : yes or not necesarily?

You will only gain about 200 lumen on turbo. Less at lower levels. Plus you will lose throw distance. I don’t think it’s worth the change. It’s probably better to keep the 50.2 and just change the color temp.

Just thinking:

Would it make sense to collect the ideas and summarize/list them somehow (e.g. spread sheet) in the OP, so Barry, Tracy, Adelina or anyone else at Sofirn would have a convenient overview of our wishes?

Good ideas except I like the UI on the C8F 21700 much better than on the C8F 18650. Click and hold to turn off is just not intuitive.

I really don’t like the timed step downs that Sofirn is using on all of their recent flashlights especially considering they are using active temperature control now.

Sofirn needs more finning on their flashlights. Sofirn flashlights have too little fins for heat shedding. Need more surface to sustain higher outputs. Redesign the C8F with more fins!

Sofirn Q8 with 4x XHP50.2 makes more sense. For 3x XHP70.2, there already exist the Haikelite MT03 TA with excellent UI, output, and is one of the best flashlight host in the size range (heavy thermal mass and abundant fins).

@ Sofirn…. Even if you do offer warmer tints, please continue to also offer the choices you have been in the 5000K – 5750K range!!

5000K – 5750K is what is closest to True Neutral White (in my book anyway) without the addition of ugly yellow or harsh blue tints.

Many of us Do Not care for the warmer tints at all.

What lag in Sofirn line up are real thrower the best they have is C8T with +/-100 KCD so I suggest

- Single 21700 with 55-60 mm. head + XPL Hi for +180 KCD or

- Single 26650 with 65-70 mm. head + XHP35 for +250 KCD/+2000 L

- SP70 SMO + XHP35 for +600 KCD/+2300 L

With the 2 switch (forward tail and light side SW) as C8F 21700 but add locator function in the side SW, omit USB charge to keep the cost low and risk of leak.

Yeah, get rid of long press on/off. Also, something in the smallest 18650 category .

I like the idea of a smaller-sized 18650 light. Something along the lines of a Zebralight or Emisar D4 would be great. Doesn’t have to be a pocket rocket either.

A higher-powered Q8 (as mentioned above) would be great too. a quad of XHP50.2 emitters in NW would be fantastic! Lots of battery life, reasonable heat-shedding capability and a great deal of power! I recall someone mentioning this mod early on in the enormous Q8 thread and it stuck with me all this time. I wonder how difficult it would be to have a small run of a light like this?

if same emitters but different tint, that could be easy and quick.

But different emitters such as change from XPL family to XHP family, that takes more time due to the voltage is different and new tests.

And a new driver, and a new battery tube, and limited power/cost, etc.

@Barry, the one thing you could do is using tint mixing.

Using emitters like the LH351D 3000k and 5000k, like in the BLF lantern!, you could pull off a very very nice beam, that even BLF members will love, with very good color rendition.

We like it a lot Smile

As said in the post above though, do you think it would be possible for the “new” Q8 to have the same LEDs as the BLF Lantern, so LH351D 3000k and 5000k 90CRI?

Not only would it make production easier, but tint mixing LEDs like the LH351D 3000k and 5000k would make for an amazing 4000k beam, that even BLF members will like since it will result in a light with a pinky tint instead of greeny tint Big Smile

We love the SST-20-W 95CRI. The 4000k currently sold on Kaidomain is the FB4 bin, which is far above the BBL so greenish. Fireflies is using the FA3 bin in the ROT66 and that was reported to have some slight green and requires minus green filter to perfect. If Sofirn can source the FA1, FA4, FD1, FD4, it should give the Nichia 9080 appearance but with better performance vs 219B. The SST-20-W 95CRI 3000k sold at Kaidomain is the HD2 tint bin and is perfect for WW.

If you go with the Samsung LH351D 90CRI, make sure you get the T1, T2, T3, or T4 bin because anything tint bins above has green tint. The groupbuys were T6 and T7 bins that were supposed to be at or below the BBL but in reality, they are all much above the BBL resulting in the yellow/green tint.

I would love to see the SF10 with a 5000K Nichia or Samsung emitter. Three special BLF editions, copper, brass, stainless and titanium. With a screwed on deep carry clip. I would buy a few of each.
