That really is comparing apples to oranges. The whole point of the X21 is that it is the best and brightest handheld LED torch. It is not like the Lightforce models which you are comapring it to as the X21 uses D cells inside the torch and is very streamline, while the lightforce uses is very bulky. Also, IMO it is much easier to spot game and differentiate colour when using white light from LEDs or HIDs as opposed to yellow which blends in with the colour of a lot of game, leaf litter, dry grass and trees. Add the conversion onto the lightforce and you're looking at more than you can get an X21 for.
I can also imagine that the Lightforce wouldn't last nearly as long as the X21 on the battery when you're powering a 100W globe.
I do agree there could be a tad more focus on the X21 but we've never had trouble picking out game. I don't find it hard to whack up a pair of binos or a scope to check whether its a stump or not, we do this multiple times every trip out, even under 100m.
I find the comparing a P7 at 100m to the X21 it blows it away, the X21 comes into its own out past 100m where all other lights fail. We were also contemplating getting a walkaround Lightforce but not since we've used the X21.
