The SP40 returns to the mode previous to the double click for turbo, whether that mode was off, low, medium or high, when you single click from turbo.
Yup, just not a fan of that
If anyone tries the superlube/silicon grease on these Sofirn sp40 mount rings, please report if it works. This thing is so tight and is nearly impossible to rotate. I’ve never used superlube on anything but threads but I can’t think of any other ideas to loosen this thing.

Thanks Pete
looks like a nice unit, i ordered one
That’s a great price for a PD in/out battery bank.
:person_facepalming: Yeah, I should have thought of that, thx guys…still might try to work a little superlube under the mount rings but kinda worried it will wind up in my hair or skin…good output on this light I was comparing it to Skillhunt H03 and it is brighter although SH has bead optic.
Are these the exact same as the Thorfire penlights? I have a TF in silver, but this was so cheap I figured what the hell and ordered one.
Pretty much, the sofirn I just got has more knurling around the tail section where the clip attaches. Other than that pretty cloney.
/\ . What he said.
Cant resist cheap good lights lol, penlights fit nicely into backpack interior pen loops…he mumbles trying to justify another flashlight purchase
I’m the same way Blackbeard…. :person_facepalming:
The struggle is very real! . 
WUBEN 1200 Lumens LED Flashlight USB Rechargeable (18650 Battery Included). The $29.99 price is discounted $12 with code 85MZMJ7W.
Thanks Pete….bought one at 13.99 because I don’t know what a 5% clip coupon is….
There was an additional 5% clip coupon visible right on the product page yesterday. It appears it’s no longer there. Still a good deal at 13.99. I just got mine today and can confirm that it can deliver the stated voltages and current, and it can recharge itself using 9V/2A input, which is nice. I haven’t yet done a discharge capacity test to compare against my 10,000 mAh Anker. Quality seems fine.
UPDATE: Capacity Test
Omars 10,000 mAh
Measured energy using 1A discharge load: 34,607 mWh
Calculated capacity at 3.7V: 9,613 mAh
Anker PowerCore II Slim 10,000 mAh
Measured energy using 1A discharge load: 33,217 mWh
Calculated capacity at 3.7V: 8,978 mAh
So, this power bank slightly beats my Anker which cost twice as much, and Anker doesn’t even have the nice % capacity display.
18650 powered Emergency Road triangle thingy $13.23
Never researched these things so might be cheaper on AE/BG/??
