Most portable devices available on the market nowadays are powered by rechargeable batteries, which are much cheaper, at least on the long term, than their "classical" counterparts. And that's exactly the reason why the SureFire company launched the SureFire 9AN Commander, a device powered by an internal rechargeable battery that provides certain very interesting lighting options.
Thus, the Commander is a rechargeable, compact, dual-output, high-intensity flashlight recommended for tactical, duty and general use. The device features two independent lamps in a single reflector, capable of providing both a long-runtime beam with the same amount of light as a big two-D-cell flashlight, or a tactical-level beam with seven times the light of a two-D-cell flashlight, which is bright enough to temporarily blind and disorient a person during nighttime.
As most other flashlights from SureFire, this particular model is also quite tough, since it features a rugged aerospace-grade aluminum body, Mil-Spec Type III hard anodized in black or olive drab, as well as a sealed, waterproof o-ring that prevents the water from reaching the battery, and features a switch lockout that prevents accidental activation during transport or storage.
The 9AN Commander has a maximum output of 140 lumens and a minimum one of 20 lumens, and works for around 40 minutes at maximum output (or 2 hours at normal output) with a full charge of its B90 Ni-Cad internal battery. Moreover, it’s a bit bulkier than other models, as it measures around 20.32 cm in length, at a weight of around 362.87 grams.
The device is available either on its own, with just one rechargeable B90 battery (8NX000), for around 190 US dollars, or as a complete system that includes two batteries, a mountable SmartCharger charging cradle, AC transformer, and DC auto adapter (for 258 US dollars), the main advantage here being the fact that SmartCharger protects charging batteries from voltage spikes.
