No, not sliced.
You can’t go by that. That was written before TA had any calibrated source for his Lumen Tube and it was reading about 30–40 too high. I can’t remember the exact number.
You also have to factor in that he’s measuring a raw led with no reflector or lens. If you put that same led in a flashlight, the output goes down based on how efficient the reflector and lens is.
I don’t see us fighting at all. We are just trying to figure stuff out. There are mysteries to be solved.
Sofirn SP70 is a reliable, beautiful light.
Was there a generic code to get the Sofirn SP70 discounted on U.S. Amazon. Or will Tracy PM me the code?
I had to PM the Sofirn account here on BLF.
Thanks for the heads up

SP70
Are the Sofirn 26650 cells that are included in the kit protected cells?
No. They offer the older 26650 and the newer high drain “HD 25A” and both are unprotected.
Sorry for the newbie question, but should I leave unprotected cells in my lights when they are not in use? Is there a safety concern? Again, apologies for the naive question.
Thank you!

Mine did arrive. I have to say for $50 it’s surprisingly well built and really a good all around light!
It depends on the specific light. Some lights have very low parasitic drain and some don’t. If you aren’t going to be using a light for at least a few days then it’s best to mechanically lock it out. The SP70 has the tail switch to cut power. Some lights with anodized threads allow you to turn the tail cap half a turn to cut power. Lights with raw threads might require taking the battery out.
Some lights may take a couple of years to drain the batteries while other lights may only take a couple of weeks.
I lock out most of my lights mechanically. The ones I don’t are used pretty often and have very low drain. They also use protected cells.
All my lights using unprotected cells get locked out.
Thank you so much! What about the SP70, E07 and D18? Again, trying to learn without burning the house down. Your last post was very helpful!
The SP70 has a physical switch, so just turn it off.
The E07 and D18 have very negligible battery drain during lockout/no aux LEDs, so no problem there too.
If you want absolute certainty, just twist for a mechanical lockout on the D18 and E07.
I’m sure it was told somewhere but can’t find it. Does anyone know the driver diameter?
I got mine today, and I actually like it more then I thought I would. What are the lumens #s people are seeing? I just did mine.
W/litikola Black 26650’s fresh off the charger.
Startup is just north of 7k, to be exact 7045 LUMEN’s
And
@ 20 seconds its at 5855 LUMEN’S
I’m happy
The driver diameter is 30mm, so it should also fit the Convoy L6 buck driver. The LED board is 40mm.
My SP70 (kit version) has arrived 2 days ago. I’m very satisfied with it. I didn’t find any imperfections on the body/anodization nor in the reflector. It seems Sofirn made big progress in dust-free assembly. 
Those 26650 cells included in the kit version (from Amazon DE) seem to be their standard 26650s with 5.500mAh and without “High Drain” label.
Alles klar, danke!
