Lumens = total light output, but this output can be dispersed in all directions eg a lightbulb. High lumens eg from a multi led torch with several small reflectors might typically give you alot of flood but less throw.
Intensity of the torch's beam hotspot is measured in lux or candela. kcd = thousands of candela. A torch's beam hotspot might be expressed as say 100k lux (or one hundred thousand lux) or 100kcd. High lux/kcd torches are throwers.
XML leds have very powerful lumen output but XML lights can be very good throwers when they have wide reflectors eg 63-68 like these two maxtochs. The xml leds also retain good beam width = multipurpose lights
XPG2 is another type of led - generally gives high lux/kcd but without the beam width. More towards pencil beam.
Both good leds - depending on what you want to do with your light. XMLs probably the most popular leds on the planet today.
