Hi, I've been into flashlights for many years but have never posted on any forums until how. I currently own a JetBeam RRT-3 , a Fenix TK-15, a Klarus XT-10, a 35W HID from AE Lights, an MVP 700 lumen, a Four Sevens S-10, and an Olight M20 and SR-51. I'm really intrigued by the Elektolumens ST90, but have seen virtually no independent reviews on it. Does anyone out there own one or seen one in operation? I'm most interested in how it performs compared to the Olight SR-90 or the TK-70. I wanted to buy a TK-70, but was put off by the need to buy separate D size NiMh batteries and a charger. Any information on the ST-90 would be helpful. Thanks
