Among those Mag Instrument flashlights with step-down regulation, the regulation works differently on some than on others. Take, for example, the regulation on the Mini Maglite Pro LED 2-Cell AA and Pro+ LED 2-Cell AA. After a few hours of operation, these flashlights fall to about 10% of full brightness; they do not return to full brightness unless the power is cycled. | Among those Mag Instrument flashlights with step-down regulation, the regulation works differently on some than on others.

(Some say it was also designed to boost [[ANSI-NEMA FL-1#Runtime|ANSI/NEMA FL-1 runtime]] ratings, which measure the time the flashlight runs before falling to 10% brightness.) | ||
