I wrote up the 4*xpg mj-872 review mentioned up above.
I can only add that I’m a fan of cheap lights and tend to buy one each year (which makes them not so cheap!) I’ve owned an original P7 bastid, a mickey mouse and and XML before I got the mj-872.
I dont quiet know how to put this – but similar to Northwind – the XML’s hotspot overwhelms my eye (or minds eye) : if that makes sense.
When in the woods at night the XML has a small fantastically lit and well defined hot spot. On the other hand it is very difficult to tell where the centre of the mj-872’s beam is. It’s that “wide” in use. But it is a lot more expensive.
stayhigh – the later batteries are much much better sealed. The one with the display is so sealed could probably be used outside a submarine. But as someone pointed out – they are heavier than the recent non-display ones.
