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.
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.
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
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.
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.
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).
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.
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).
