Probably not a fair answer yet, but based on the reviews and function, I would say the Manker E02. Not as cheap as some on here, but for $20 it has all the features I want in a light. firefly, decent low, good high, and an unexpected near 200 lumen turbo with a nichia 219 emitter.
Also love the fact I can get moonlight, last mode (planning on the 10 lumen low here) or turbo directly out of the off mode. no need to cycle through modes, just click accordingly. Also my first red light
Looking forward to the L shape light as well, and my second clicky. i don't normally like clickys as I don't want to hear click when i turn the light on or change mode. Guessing the e-switch will be quiet enough for my taste.
