Mine is an unbranded chinese special that I got for like £18 off aliexpress but I love it when working outside in the colder seasons. It's got 3 settings. I have two gripes with it, the power/led colour choice doesn't make sense on mine, it goes red = low, white = medium and blue = high. Maybe thats why it was cheap cos it was programmed/wired wrong. The other gripe is that the pocket for the battery back is tiny. Mine struggles to fit a 6000mah bank let alone my 20ah Anker so worth bearing that in mind.
