Brightness, no comparison with the old Maglite bulbs and Xenon: the "Led Pro" are almost twenty times more powerful (245 against 14 lumens) ... For the rest, there are quality Maglite (tightness, strength etc.) . Please note: "Led Pro" Mini R6 are 2 cm longer than the Mini R6 Xenon. For the night, reading in bed or find the bathroom door: Xenon enough. For the night, walking, light a table, etc. do not hesitate: the LED Pro is a very good investment.
