Well as the beam shots from my own light are used a fair amount, I would like to add my thoughts, having used it for a while.
It's not great, TBH I was happy using a 12w Lumi spot, but being one for the latest & greatest I 'bought into the technology'. My mate is currently using my old Lumi & its perfectly usable, a nice warm light that doesn't just blur things. And it has the same, if not more 'usable' light, but again its subjective.
Yes this throws out much more light, yes it is much lighter, yes the run time is longer, yes it only cost £50.
So, if you don't already have a decent light then its 'THE' bargain of the moment, you can't get more 'bang for buck', but if you have a usable system, just don't go expecting the world.
Cheers.
