A couple of years ago I decided to go to USB charging lights for EDC. I use or carry all of these daily.
The i1R EOS is on my key ring, and while it's pretty word, it still works.
The Streamlight Microstream USB is clipped to my pocket, but kets the leasy use of the three. I often leave my current job after dark, so it's mainly for use on my way to my truck.
The ProTac 2L-X is mainly for home. When we take the dogs out, even though we have yard lights, I light to be able to look around for other animals. I've kept mine on the standard programming of high-flash-low. I programmed the one my wife uses for high only.
