1. SP70 will be a single emitter flashlight. How about:
SPX17? (the X could mark, that it is a more complex flashlight, and the 17 would mark, that it is 17 thousand lumens at maximum)
or
SPX144/SPX18 (similar, but marking emitters distribution, not thousand lumens)
2. I would suggest it this way:
one XHP35 HI for throw, let’s say it is about 2000 lumens with 200000 candela alone - 5000K 80 CRI (maybe reflector diameter is around 6.5 cm, SMO)
eight further emitters as below (alternating around a circle):
four XHP50.2 for comfortable flooding: let’s say it is about 1750×4 = 7000 lumens - 4500K 90 CRI (reflector diameter is around 3.5 cm, stronger OP texture)
four XHP35 HI for slightly more concentrated (intermediate) beam: 2000×4 = 8000 lumens - 5000K 80 CRI (reflector diameter is around 3.5 cm, SMO)
—> 17 000 lumens total, maybe user should activate these all simultaneously, or one by one (e.g. only flood or only throw, or flood + intermediate or throw + intermediate) - with at least one dedicated button
3. I would suggest 2 battery compartment serially connected as this: a single compartment could be of 3× 21700 batteries parallel, this will give not too thick battery tube, but a great possibility to support high current cells of 20-30 ampers and above (Vapcell / Shockli 4500mAh 20A /LS21700SF/ or Samsung INR21700-40T 30A - resulting a 13500mAh 8.4V battery pack capable of 60A continuous (max ~ 360W) or around 11000mAh 8.4V battery pack capable of 90A continuous (max ~540W) - also, Sofirn 21700 4000mAh ~15-20A could be good as well)
Actual flashlight power could be around 200-240W, but we need to over-design the battery pack to let the users have less battery strain, while using this flashlight.
Thanks for the answer Teacher, there would be a great push if Sofirn could do that…. Even if manufacturers could not/would not do this properly,doesnt’t mean they couldn’t find somebody to do it,isn’t it? I mean it’s not the same finding someone to do 5 pieces or 500?
Just a slice is not that hard but it makes ugly yellow corona. If you want to do it like me to remove yellowness from corona it takes almost half an hour per led to make it right. That will raise the manufacturing cost very much plus it has high risk killing leds.
Mark me down for something that at least doubles if not triples the Q8. Otherwise 50% more isn’t worth it.
Prefer the 21700…but should come with them. Also USB rechargable. My current charger can’t go past 650 and yes, I can buy outside stand alone connector for the 700s, but obviously slower.
I wonder if after Chinese New Year, there’s been a rush to fulfill orders that have been piling up. Not showing up here could well mean that they’re too busy working on the SP70 too.
Its a hard light to make especially the reflector. We wanted some modification done and so did the people at Sofirn so they are trying parts to see what works best. They where hoping to be done by March/April so its not really late.
