Reviewing the Sofirn SP10V3 LED Flashlight

Quite some time ago, I reviewed the SP10A from Sofirn. As cool as this small AA flashlight was, it’s now had a much anticipated update! So with that, I’m reviewing the new Sofirn SP10V3.

Operating the Sofirn SP10V3

The battery is inserted positive side up.

Press the switch and away you go! A holding press advances the modes from low to high. As with other lights of this type, moonlight, turbo and strobe etc, are hidden.

  • For moonlight; press and hold from OFF
  • For turbo; do a double-press while ON or OFF
  • For strobe; do a triple-press when ON or OFF
  • For SOS & beacon, activate strobe, then press & hold for about 5 seconds (SOS is first; for beacon, press & hold a second time)

A single press from the constant modes turns it off. A single press from any of the flashing modes returns it to where it was when they were activated. If you did a triple-press from OFF, it’ll turn off. If the press was from a constant mode, it’ll return to THAT mode.

Charging the Battery

Sofirn supplies a simple, USB connected charger.

Just connect it to the source of your choice, and place the battery in the cradle. As long as the battery has had some use, the tiny indicator on the charger will be bright RED. If it’s GREEN after the battery is inserted, wiggle it a bit. The connection tends to be a bit finicky. It’ll turn GREEN when the charge is finished.

The charger works the same way with an NiMH cell.

Low Voltage Warning

There are no illuminating indicators on the SP10 (such as a light under the switch). What you’ll get instead is the inability to operate the light on turbo. Instead you’ll have “high”. As voltage drops further, high mode will be replaced with medium/low.

On very low voltage, it’ll blink twice per minute.

Keep in mind the above indications are only when using rechargeable batteries.

Random Sofirn SP10V3 Thoughts

Just like the recent Sofirn SC21, this new version of the SP10 has a lot of potential.

I suppose it’s just an example of advancing technology, but it’s nice to see a AA light that embraces a lithium battery right out of the box! Most manufacturers of AA lights, “kowtow” to the “basic” flashlight user who buys alkaline batteries at the last minute wherever they can. Leaving them IN the light (without use) over long periods, allowing the battery TO LEAK, is another common practice.

With Sofirn supplying a 14500 lithium battery with the SP10V3, there’s no reason for anything related to the above statement, to ever occur. Naturally you CAN use it with a standard battery, but unless you’re in a “charging pickle” I can’t imagine why you (or anyone) would.

They chose not to make the light USB rechargeable, but to include a basic “1 bay charger” instead. This is okay and the charger is pretty fool-proof. But as I said earlier, its connection is finicky and the battery might need to be jiggled when first inserted.

Despite not having an actual indicator for low voltage, it’s a great little light.
