The XL200 is, in relation to the XL100, far superior: the through-connection of many programs is absolutely no problem and works very well in conjunction with the motion control. More superiority: the luminosity! The "little thing" is pretty damn bright !! Compared to some other models the shape is very well suited thanks to the lack of "nooks and crannies" for tighter pockets, without wishing to tilt somewhere. The light output is enormous and very well suited for illuminating dark paths. The cone of light is neither too small nor too large dimensioned. The lamp is very harmonious in the environment. From the level of craftsmanship and the materials used leaves nothing to complain one occasion! Minimum weaknesses can be seen in such things as lack of wrist strap (for the purpose of hedging), filigree seemingly reflector disc and two actually unnecessary modes (strobe and Morse Mode). On / Off with dimming - sense; NiteLight - sense; SOS - can be quite useful! Love Mags - please builds the XL300 with 3 functions and 250 lumens ;-) Cheap this light is certainly not - but what Billigfunzel already provides this brightness in conjunction with waterproof, drop resistance and guarantee! Therefore: strong buy recommendation!
