This is a field test of the ArmyTek Crystal, featuring five lighting modes ranging from Firefly to Beacon. The White/Red model was tested in this review.
I was asked to review this light and do try to accommodate such requests whenever possible. The light has a wide variety of mounting options and includes both Red and White Beacons. So, I was personally interested in the light for possible use in wilderness Search and Rescue. I have frequent need for emergency and auxiliary lighting. These needs range from hot swapping headlamp batteries in the field to area lighting during the rescue phase of an operation.
The review was filmed on a wet, rainy, cold night at the Arbor Hills Nature Preserve in Plano, Texas. All segments were shot one-take (with no retakes) using an iPhone 14 Pro MAX.
If you would like to see additional tests or comparisons with this light, please leave a comment. As always, thanks very much for your time and thanks for watching the video.
