This feature (which is enabled whether or not your batteries are disposable) prevents the flashlights from using up disposable batteries so quickly.<ref>Chicken Drumstick (27 August 2012) [http://budgetlightforum.com/node/8080#comment-220524 Re: Review: Mini Maglite Pro+]. ''BudgetLightForum LED flashlight forum''. Retrieved 24 January 2013. "It’s regulated to offer the max performance and run time off of alkaline cells. The downside is you’ll see little improvement using lithium primaries or Eneloops. But this is all down to the target market and expected customers I guess."

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''. Retrieved 29 January 2013. "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)."

For many customers, Mag flashlights with step-down regulation are fine choices.

Opinions seem to vary as to why, some think it is to prevent excessive heat buildup, others think it is to preserve battery life. Either way, if you are outside in the dark walking or working and have the light on chances of your eyes even detecting the drop over an hour or so is pretty slim. If for whatever reason you think you need full power again, simply turn it off and back on and the cycle starts over again."
