For 2016, Streamlight introduced a pair of new lights they are calling Dualies. The new lights feature two light sources in each torch and are intrinsically safe.
3AA ProPolymer Dualie
As the name suggests, this flashlight has a polymer body and operates on three AA sized batteries. It has two C4 LEDs that can operate in concert to provide ample lighting for both searching and movement. The forward LED produces a spot beam than measures 140 lumens and 7,300 candela with a beam distance of 171 meters. This beam is designed for searching and other spot light application.
The side mounted LED produces a flood light that is also 140 lumens, but with only 80 candela. Understandably, the beam distance is only 18 meters. It is designed to provide a very even flood light to illuminate a work area.
The two LEDs can work together for a total light output of 245 lumens. According to the company, the beams are angled in such a way as to eliminate blind spots when used for navigation. With alkaline batteries, the flashlight will operate either LED for 18 hours or both for 9 hours.
3AA ProPolymer Dualie Laser
On this flashlight, Streamlight replaced the flood LED with a red laser pointer. The spot beam is slightly brighter (150 lumens, 7,700 candela) with a 17 hour rated run time. The red laser (<5mW output) will run for 70 hours solo or for 12 hours with the light also on.
If you are not familiar with the term intrinsically safe, this is a rating that states the equipment in question – in this case the two Streamlight flashlights – will operate in hazardous locations and not generate enough heat or electrical energy to ignite flammable or combustable materials. For anyone working in hazardous environments, this can be a very important certification.
A SWAT team dealing with meth labs or an EOD team working a bomb maker’s facility, these kinds of lights could be useful.
