4sevens introduced a hand lamp with a record capacity of 15,000 lumens. Its emitter consists of 18 separate LEDs that eat from 32 lithium batteries. Despite the high efficiency of LED chips, with this power they have significant heat transfer, so the case has a built-in fan. The hexagonal form provides for the connection of several such devices in one block, for those who seemed not light enough. Lantern price $ 2500.
