| | | I've always just popped a red filter on the front - I have a red filter for my Fenix LD20, and it works nicely. I also have a couple of Solarforce L2s with replacement coloured glass filters, but unscrewing stuff is a bit more involved than just sliding something on the front. It'd be worth making sure you can get one to fit whatever you end up buying. Looks like Fenix make one for the TK series, but I'm not sure what the options are for the JetBeam (though I read a comment that Olight make a filter that might suit). Those lights will throw pretty well, but 200m might be a stretch. The thing is, though, really long thrower lights aren't great to use up close, anyway. I have a dedicated thrower, and it's a pain to use at close quarters, having a very bright spot in the middle, and limited spill around the sides.

| | | What the hell, people. What can you see at 200 meters, anyway? Trig. If you're looking at a 1m thick object (Very fat man) at 200m, he is tan-1(1/200) = .286 arc-degrees. That's 1/1256 of a circle. I'll grant that normal visual acuity is 1/60 degree... I think that to get useful light at that range, and also a flashlight you can walk around with, you'd need an aspheric zoom lens. Jetbeam gives 'torch lumens,' which are the real ones that you send towards what you're looking at, instead of emitter lumens, of which many are lost inside your flashlight optics. The JetBeam will probably do what you want, the warm tint is technically less bright but most people prefer it over cold white for outdoors use.
