those 2 are good, top one was available in usa but called black and decker, and was orange color, its incan version was actually better than led, brighter and throws farther, it is actually has a reflector that works great with small die leds, i moded one with xpg2 and it worked great. the bottom one is Australian dolphin, which was not widely available in usa, however it was available for a short time under different name. i have one that was shipped to me from australia, old inc model, wich works awesome with halogen hpr 52 bulb, very sharp focus and far reaching beam. Actually in my experience all of those 6v lanterns became worse with leds in it, they used low power leds, due to basically none existent heat dissipation, they all have a thin aluminum circle as a heatsink, that works ok with 1-2 watts, but no more than that, they run longer than bulb, but nasty blue weak leds, really do not improve them.
