This is an interesting little light. Retails for $45, uses common AAA batteries (1 set of Duracell included), and has 4 colors available to the user with simple twist selection. It is packaged with a lanyard, instructions, and the aforementioned Duracell batteries all in the familiar LED Lenser cardboard box.
From the LED Lenser web site: “Why the need for four colors?
White light lends itself to seeing best at night, where objects appear natural in color.
Red light will maintain your night vision, as well as being useful for signaling.
Blue is useful for signaling as well, and also for following blood trails if your hunting trip extends past daylight hours or for uniformed professionals.
Green is an excellent choice for fishing and it increases contrast while viewing objects in low visibility situations, without being as intense as white light.”
The beam is very diffused without a lot of throw or a defined hot spot. LED Lenser references a “Prism-Diffuser” lens. It works quite well.
This is one of those lights that evokes the “why does one need this?” response. I would counter with, “why not?” Retails for $45 but less than $40 on many sites. Runs on ubiquitous AAA batteries. Throws a nice floody beam in 4 colors. I have used this one around the house and on dog walks and find it to be a useful lighting tool.
