Giving this more thought, the DX80 is bright enough for hand held camera photos on auto settings, and gives good results. Low enough ISO setting to not be grainy.
I think these new monsters are expensive, OTT, and not really suited to underground use.
With the DX80 available at £199 from these LEDSupermall people, it appears to be a German company, that is what I would go for.
If you want a powerful thrower torch, you dont need that power if you choose one that uses Cree XHP 35 emitters which will focus to a controlled beam. The Imalent R90C looks good at £250.
I think its going a bit silly now with built in fans etc. The Acebeam sticks the extra XHP 35 in just to be a tie breaker.
The above really summarises not only the big issue with my own lamps but the 'output politics' of Chinese torches per se. Its no good just cramming in as many emitters as you can and claiming daft lumens, or doing this and driving them to full power and claiming honest lumens. The output has to be controlled or you just end up with a massive 'room light'.
Probably good for photography though.
