I cannot help you locate any, but I can attest to the usefullness of them. I have carried an ASP Saphire perpetually since last christmas. I have no idea how many times I have used it. I used it again today to take a shortcut through a mountain through an abandoned mine shaft. Yes, its that bright. I keep a Photon II in my survival tin, but it is not as bright as the ASP. I dont even bother with any of my smaller mag lights anymore. I even replaced my red filtered mag light I kept for night flying with a red ASP that I hang around my neck.
