Retrieved 27 January 2013. "As efficient as LEDs are, heat is still produced and has to be dissipated, so step-down regulation is used to prolong battery life and reduce heat."

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.<ref name="Pro" /> This regulation was designed to try to prolong the life of alkaline batteries. (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.)<ref>[[User:Brted|Brted]] (28 January 2013) [http://flashlightwiki.com/Talk:Mag_Instrument#Thermal-management_article_section Talk:Mag Instrument] ''Flashlight Wiki''.

"The effect of this would be to keep the light running cooler, but also to extend battery life (and some say to distort the FL-1 runtime rating which gives you credit down to 10% brightness)."
