Sofirn Tactical Flashlight 1200 High Lumens, SP31 V2.0 Super Bright Torch with Cree XPL HI LED, EDC Pocket Size, Battery (Inserted) and USB Charger, for Camping Hiking Fishing

******************************************UPDATE 10/7/2019 FOR THE SC31B***************************************Since it appears that Amazon will not have separate reviews for the SC31B, I’ve edited my initial review for the SC31 with this add-on to cover it. I’ve left that initial SC31 review intact as, except for the new LED and its performance, it remains valid for the SC31B as well.The Sofirn SC31B is an upgrade to the SC31 and so has similar features and appearance. The SC31B utilizes the SST-20 LED as opposed to the XPG3 in the SC31...an increase in lumens from 610 to 1000...and an increase from 3 light modes to 4 well-spaced modes in order to better utilize the increase in power. Those modes and run times are listed in the online description.The SST-20 LED die has a relatively small footprint and is similar in size to the XPG3…so it is a good choice to maximize throw (distance viewing) in a tube light. I was impressed with the throw the SC31 was able to deliver in a 610 lumen light...but the SC31B adds nearly 50% more throw and, with 207 meters, is one of the better tube light throwers I’ve seen.That is due to its relatively small hot spot as well as the increase in lumen output. However, it has totally adequate flood to provide a broadviewing area at closer distances.The one con of the SC31B, for me personally, is the color temperature of the LED. Its a cool white at 6500 K. I considered the SC31 to be a neutral white and that’s my preference. So the SC31 wins on that score. That said, you may prefer a cool white, but in any case, if you want a compact thrower, cool white is not that big of a price to pay.In summary, the SC31B represents a significant performance boost to an already great light.*************************************************************************************************************************The SC31 is an excellent light for someone wanting a simple user interface (UI). Just like the lights of old, it is turned off and on with a single click of the switch…while still offering 3 different levels of lighting which are accessed with a hold down of the switch after turn on. Short of a single mode light, its about as simple a UI as you can get. The online description is a bit lacking so my purpose here is to provide a more comprehensive review to provide answers to questions some may have.Build quality, as on all Sofirn lights I’m familiar with, is top notch. Well anodized and solidly built. Both the head and tail cap have anodized threads to allow lock out of the light with a simple ¼ counterclockwise turn to the tail cap…a useful feature with an electronic switch. Its rated to withstand a drop of over 3 feet and over 6 feet of water submersion. It comes with spare O rings, a lanyard, and a charging cable…but no power supply. Not an issue if you have an Android Smart Phone…its charging power supply will work perfectly. Otherwise, you can use the USB port on your computer.There is no place to attach the lanyard to the tail. The only choice is attaching it to the clip. So, I don’t consider the light to be compatible with a lanyard. The flat tail does make for an easy tail stand for use during a power outage.Springs on both the tail cap and head allow use of a flat top battery.I would consider the beam to be a neutral white. However, the hotspot is on the cool side of the spectrum while the spill or flood tends to be warmer. There is a tint shift across the beam…more noticeable on a white wall than in outdoor use.The reflector is of the orange peel type to provide a smoothed out beam. The lens has no AR (Anti-Reflective) coating.The clip is reversible by simply switching the position of the tail cap and head on the battery tube. This allows the light to be clipped to a hat brim for free hand use… Few lights have this feature.I checked the voltage of a freshly charged battery…4.20 volts…so charging system works great.In a tube type light such as this, the smaller sized die of the XP-G3 LED, improves the throw over what would be provided by an XM or XP-L LED at equal lumen output. It provides plenty of light for most purposes. To put that into perspective, the 600 lumen SC31 has a listed beam throw of 154 yards as opposed to 167 yards for the 1300 lumen SP32A V2.0 with an XP-L2 LED (one of my favorite lights). The light has a well-defined hot spot which is noticeably smaller than my XP-L tube flashlights. This light does have thermal protection in that it steps down to 400 lumens after 5 minutes and then to mid and low as the battery drains.Although not listed in the online description or the manual, my light has memory. That means it remembers the light setting it was on when it was turned off. Turn it on again and you will have that setting. It also has strobe which is accessed by two quick clicks. A single click returns it to the setting that it had when strobe was activated. I would prefer it have no strobe as I have no use for it and find it really irritating when it is built into the normal mode sequence. At least the strobe on this light is hidden.I didn’t test this light for LVP (low voltage protection). LVP is not listed online or in the manual and I would take a guess in saying it doesn’t have it. However, if you use protected batteries this would not be an issue as the battery will shut down when low voltage is reached. Also, a rapidly blinking switch provides a warning when voltage becomes low…turn off the light when that happens and you’ll be fine with an unprotected battery. The light comes with a 2200 mah 18650 battery that appears to be a protected one. That is far from state of the art in capacity….which currently stands at 3500 mah and that is what SOFIRN used in determining run time. So, If you are using the 2200 mah battery, the listed run times need to be adjusted by multiplying by about 60% due to the capacity difference. The listed run times for each mode are:Lumens/Run time………..High (600)/2 hr 42 min…….Med (200)/9 hr 7 min…….Low (10)/179 hr 33 minNote that you are not going to run this light on high for nearly 3 hrs. That value represents how long the light will provide usable light on high…stepped down lumens are counted.This light is a great choice for users wanting an easy-to-use versatile flashlight. No need to remember whether to use short clicks, intermediate clicks, or long clicks and how many clicks to use for accessing features. Its ready to use right out of the box so makes an excellent gift choice.

I admit it, I love flashlights. Maybe a bit too much. But as such, I own several Sofirn flashlights and they're all pretty darn good. The SC31 is no exception. It is bright, well built, and compact (easy to carry).If you're comparing flashlights and have concerns about this one being rated at 610 lumens instead of 1000+ lumens, don't be! Because of how our eyes interpret light, there really isn't a big visual distinction between 600 and 1000 lumens. And honestly flashlights of this size *cannot* maintain their output with 1000+ lumens - they'll get so hot that they'll burn your hands. So inevitably, nearly all tube-style flashlights will "step down" after a few minutes. The SC31 steps down from 610 to a still-respectable 400 lumens.The Sofirn SC31 is a great value, especially considering the built-in micro-USB charging (charge anywhere!) and the included battery. It'd be hard to beat this for the price.If you have any specific questions about this flashlight, don't hesitate to ask!

The sofirn sp31v2 makes the third sofirn light in my collection and with this v2 model sofirn builds on a already great light.My one and only gripe with sofirn in general is the packaging they ship they're lights. Understandably they save money on packaging to be able to provide a great light at an affordable price. The box is a generic looking black and blue cardboard box, inside you get the light, 1 18650 battery, lanyard, spare O-rings and micro USB cable for charging . the light runs on one 18650 or 2 CR 123 batteries. The light is made of premium anodized alluminum alloy, it is also IPX8 water resistant perfect for outdoor use. The sofirn sp31 v2 has two switches, 1 tail clicky switch for momentary on and a side switch that is used to cycle through all the modes.Using the sofirn you have 5 settings (eco,low,mid,high, and turbo). On high and turbo the light puts out a generous 500 and 1200 lumens. The light beam has a perfect mix of throw and spill. Overall I highly recommend this light for those looking for a great quality light at a affordable price.

I bought two of these. I love the size of this flashlight especially considering it is USB rechargeable. The color temperature seems 5500k, cool white, but fortunately not bluish like other cheap lights.I measured using the calibrated Texas_Ace Lumen Sphere to 446 lumens and 469 lumens slightly after turn-on using fully charged Sony VTC6 batteries. The included Sofirn batteries measure less lumens. This is lower than the 600 lumen spec. Sofirn has been conservative with their lumen specs on some of their other lights like the 18650 C8F but over rated some of their other lights like this one and the 21700 C8F. But Sofirn in general is more honest than 95% of the other flashlight brands on Amazon that inflate their lumen ratings to couple hundred percent of actual.The user interface is decent but not as good as the one on the Sofirn SP30A. The Sofirn SP31 and SP32A also have better UI than this but they lack USB recharge. I only bought this for modding because Sofirn lights are easy to mod and I basically modded over a dozen Sofirn lights. There seems to be a weak glue in the thread but it's not difficult to turn with the right tool.SOFIRN PLEASE DESIGN YOUR LIGHTS FOR EASY MODDING. DON'T GLUE ANYTHING IN YOUR LIGHTS OR YOU WILL LOSE CUSTOMERS!I would rate this 4 stars but the price is good so I can't expect more.
