I ended up replacing my Streamlight Microstream with another Streamlight Microstream. I tried the Macrostream, but it was bigger, brighter, and the battery didn't last as long. It ended up dying on me during a recording session, and I had to use my phone. Holy shit using the phone sucks balls. I can deploy my flashlight in a fraction of the time it takes me to get my phone out, let alone open the flashlight. Plus, a phone is a phone, not designed to hold as a flashlight
My new Microstream defaults to low at first press, and then double tap for high, which is better than the opposite. This battery should last even longer between charges, which was incredible to begin with. I finally feel like I properly replaced my lost flashlight.
