Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang SUREFIRE dari 3G Electric.
What battery types do SUREFIRE flashlights like the G2X-D-BK use?
SUREFIRE flashlights, including the G2X-D-BK model, are designed to operate on CR123A lithium batteries. The G2X-D-BK ships with two CR123A cells. These batteries are 3V DC, lithium chemistry, with a typical capacity of 1,500 mAh. SUREFIRE also sells CR123A batteries in multi-packs (e.g., 12-pack SF12-BB, 2-pack SF72-BB) for replacement or bulk use. The flashlight’s circuitry is optimized for the voltage and discharge characteristics of CR123A cells; using other battery types may affect performance or safety.
How many batteries does the SUREFIRE SC1 storage case hold?
The SUREFIRE SC1 Battery Storage Case holds six CR123A batteries. It is a black molded case designed to organize and protect CR123A-sized cells during transport or storage. The case does not include batteries; it is sold separately as an accessory for users who need to carry spare cells for SUREFIRE flashlights or other devices using the same battery format.
What is the maximum beam distance of the SUREFIRE G2X-D-BK flashlight?
The SUREFIRE G2X-D-BK flashlight has a maximum beam distance of 187 meters. This measurement is based on the flashlight’s 600-lumen output and reflector design, which produces a focused beam suitable for medium-range illumination. The beam distance is specified by the manufacturer under standard testing conditions.
Are SUREFIRE batteries rechargeable?
SUREFIRE’s standard product line, including the SF12-BB and SF72-BB, consists of primary (non-rechargeable) lithium CR123A batteries. These are single-use cells with a 3V DC output and 1,500 mAh capacity. SUREFIRE does not manufacture rechargeable CR123A batteries under its own brand. Users requiring rechargeable options should source compatible rechargeable CR123A cells from other manufacturers, but must verify compatibility with SUREFIRE flashlight specifications.
What is the runtime of the SUREFIRE G2X-D-BK on maximum brightness?
The SUREFIRE G2X-D-BK provides a runtime of 1.5 hours at its maximum brightness setting of 600 lumens. This runtime is achieved using the two included CR123A batteries. The flashlight also has a lower output mode that extends runtime; the manufacturer does not specify the lower mode’s runtime in standard documentation. Actual runtime may vary based on battery condition and ambient temperature.
Does SUREFIRE offer flashlights with multiple output levels?
Yes, SUREFIRE produces flashlights with multiple output levels, such as the G2X-D-BK, which has two light outputs: a high mode (600 lumens) and a lower mode. The output is selected by pressing the tail-cap switch in sequence. Not all SUREFIRE models are multi-output; some are single-output tactical lights. The specific output configuration is listed in each model’s specifications.
