The Sodiumfrostglow flashlight has been developed as a piece of equipment that's rated to operate effectively in a variety of conditions, even subzero ones. The flashlight is equipped with a sodium-ion battery instead of the usual lithium-ion variety, which enables it to maintain a stable power level when being used in conditions down to -40-degrees Fahrenheit. The flashlight is rated to pump out up to 2,500 lumens and will offer a cool white beam that comes in at 6,000K to 8,000K with the ability to cast light up to 787-feet away.
The Sodiumfrostglow flashlight is crafted using hard-anodized aluminum alloy for the housing and has an IP44 rating. The flashlight boasts a 10,000mAh battery capacity that's rated to offer around 3,000 full charge cycles before losing performance.
