The Sofirn SP31 V2.0 is the latest version of the SP31 and the newest 18650 light from Sofirn. Although this is my first Sofirn light, they are known as a quality, budget friendly flashlight company. I’ve had a chance to use this light and put together a review and specs that might help you with when considering this as a purchase.
What’s in the box:
1 Sofrin SP31 V2.0 Led flashlight
1 Sofrin 18650 battery 3000 mAH
1 USB Charger
2 Spare o-rings
1 User manual
First of all Sofirn has upgraded their packing from a plain brown box they have been known to send out. Everything about the light looks and feels like a quality build. The stainless steel clip is sturdy and already installed. The knurling gives the light a good feel and nice grip. The user interface is easy and simple to use. I really like the modes programmed into this light. The moonlight mode or Eco as they call it is 5 lumens and good for close up work and the 1200 lumen mode is super bright and really lights up an area. My only complaint is because of the design the light will not tail stand. I have been informed this will be redesigned in the near future.

Tail and Head
I really like this light. I wasn’t sure how much I would like the two switch operation but I can really see how easy it is to operate. I love the different light levels from turbo at1200 lumens down to moonlight or eco mode as they call it at 5 lumens. I’m finding that I use the moonlight mode as much I do the turbo mode. The turbo is super bright and really throws the beam. Strobe is easy to access and it is separate from the other modes, so I don’t always have to cycle through it. Great light and a good value.
