I recently experienced that quick discontinuation by Lumintop, when I came across a second hand (partially broken) Lumintop Tiger I purchased (posted about it in this topic). I wasn’t even aware that this Lumintop model (including the Mini) existed; I totally missed that!
The same applies for the (regular) Tiger too!
I’ve tried finding more information/reviews about it, but besides a couple of threads on Reddit (with almost no usefull information) and a 2 or 3 basic unboxing/beamshot videos on Youtube, it is pretty much as if this light has never existed or actually has been released/launched, other than some review samples maybe!
Fortunately I was able to buy the Tiger really cheap and with about € 9,- in parts (new XHP70.3 HI and new battery springs), I should have a working Lumintop Tiger for around € 45,-, which I would consider a good deal and a waaaay better price than the (too high) original price that this light was selling for.
