They  are 488nm cyan blue laser pointers, sky blue laser pointer or light blue. This is a truly unique color of laser I have never seen before. I was skeptical it was a laser and not a flashlight. This is actually a laser and at a wavelength I have not seen offered anywhere else in a portable battery powered version. The power output is significantly greater than the 200mW listed. A great product for any laser enthusiast. Fits nicely into my collection.
