Cree specs are meaningless. We should be closer to 100 watts.

According to the tests: http://budgetlightforum.com/node/58094 and http://budgetlightforum.com/node/57715, 100 watts is about 14 amps – is that about right for the higher performance cells, which is said in the OP to be about 7000 lumens?



Yeah. It’s a FET driver and with high drains cells it should pull some pretty good amps. Sofirn was never able to tell me how many, though. Maybe it will be the 18A-19A I get with my Lexel driver L6, but I’d rather be conservative until I can measure it myself.

That sux. Sad . What country are you in?

My HD batteries were sent back by customs apparently so Sofirn have sent out some more today. My SP70 should arrive this morning according to Royal Mail.

Just received mine,build quality seems ok,threads smooth and lubed,reflector OP similar to L6,anodising shiny black,not sure about UI yet,ceiling bounce a fair bit brighter than L6,will check out later when fully dark.

The texture on the reflector should be very light. The L6, the xhp70 one, had a heavy texture. I hope Sofirn got it right.

Yours is shiny black? I though they would all be matte black.

Yea they should be matte not shiny and have a slightly OP reflector. The L6 is less OP than the S70 so maybe this reflector is similiar to the L6?

This is the issue if no one gets sent an engineering sample to check.

Shiny black compared to the L6, about the same as BLF Q8 and the OP is only slightly less OP than L6.

For anyone interested, I have published the approved manual for Sofirn's SP70 on my sharepoint, both in English and German language.

In looking over the manual and the OP, didn't notice details on the LED. 

Back here Jason wasn't sure, but thinks it went out as 6000K-6500K: http://budgetlightforum.com/comment/1485313#comment-1485313, but still we don't know the bin?

Do we ever get output bins from manufacturers?, and if we do get them are they correct, and are we able to check them?

That’s all information I have received from Sofirn, so far. I asked them if their numbers may be worth being updated since JasonWW got much better results with those 26650 batteries Sofirn has apparently provided for testing the SP70 prototype. But they didn’t want the numbers in the ANSI chart to be changed. I don’t remember the exact post here on BLF but I was told the numbers in the manual result from testing with 18650 batteries. Eventually, we need to wait and see what actual numbers people will measure once they get their SP70s.

Sometimes. We sure got it on the Q8, after great insistence of course. Just wish'n, just say'n. If we know, that's good, if we don't, that's typical.

I'm mostly worried about their driver. I can't remember where/which lights, but I seem to recall some of Sofirn's drivers being subpar on efficiency and/or standby drain. I guess standby drain isn't as big an issue on a light with a rear lockout switch. I just hope it's not a light where I feel like I want to mod the driver first thing, because then I start wondering why I didn't build another L6.

I haven’t been able to test anything because I don’t have the light. Sofirn has tested a variety of batteries, though. I believe their 5500 lumen rating is using their low drain 26650 batteries. I’m guessing they need to sell more of their low drain cells. When they tested using their 21700 and HD 26650 they got the higher lumen numbers.

I think its a safety issue for non flashlight people and Sofirn are concerned? Using high drain cells is probably not recommended for every one. Lots of 26650s are not suitable to be used in series where as most brand name 18650s will have no issues.
Check out HKJs charts and heaps of pair of 26650 don’t match which can be an issue. At what point does it become an issue? Well for some novice that may only charge cells when they are flat its a bit of a worry where as we probably charge our cells more often.

The S70S had a really high drain of 4.43 milliamps. I don’t think the mcu went to sleep. Plus the green led was an inefficient one that needed more current than some other green leds.

That was a linear driver of some kind. On their C8F, which is a FET driver, they got the drain down to 77 microamps. Much, much better, but it’s not using a constant on led like the SP70. So I hope the SP70 drain is under 400 microamps. Under 200 would be even better. I’m not too worried about it though. For storage I would cut the main power.

Is there going to be an SMO reflector available for this light in the near future?

They may use a SMO for a special edition SP70 with other tweaks, but I don’t know if it will be available separately.

So the SP70 performance is very similar to a Q8 ? you must really like the form factor then to want one (or be prepared to go through the trouble of slice/dice the led).

I’m not sure who your talking to.
I definitely prefer the form factor. I can slip it in my back pocket. I also prefer the dome on.
My Sofirn Q8 gets no use. It’s just too bulky. The beam is a bit too narrow, as well.
Everyone has their own preferences and needs which is why there are so many flashlight models on the market. Something for everyone. Thumbs Up

Yea i prefer this style over the Q8 feels more ergonomic to me. I think we will see more throw than the Q8 maybe double once we test it. Plus out of the box the SP70 can hit 7000+ lumens without any further mods fair bit brighter than a stock Q8.
