I just bought the clulite one, because it was a fraction of the price of the other.
It seems to be the cheapest rechargeable gun light around.
It's not great, but ok for rabbitting etc with .22
Filters are available, and it has a stock mounted switch.
The mount seems a bit crude and clunky compared to others, but it's quick to take on and off (no tools needed) and the angle of the beam is adjustable, which doesn't seem to be the case with any of the others.
If I had a bigger budget (and bigger calibre and a more ambitious quarry list) I'd have gone something a bit more powerful.
