* Also, as each flashlight's LED heated up, the flashlight provided less power to the LED, which caused it to dim and to produce less heat. If the flashlight was moved into a cooler environment, it instantly brightened again. | * Also, as each flashlight's LED heated up, the flashlight provided less power to the LED, which caused it to dim and to produce less heat.

In 2009, Mag Instrument modified the 2xAA Mini Maglite LED and 3D Maglite LED to each include a better heat sink. Even during extended use, those flashlights now stay at a reasonable temperature without dimming themselves. | In 2009, Mag Instrument modified the 2xAA Mini Maglite LED and 3D Maglite LED to each include a better heat sink.
