Like other lighting technologies, LED lighting does not produce only light, [http://en.wikipedia.org/wiki/Thermal_management_of_high-power_LEDs but also heat.] LED technology today is such that only about 30% of the energy going into an average LED is turned into light. The rest is turned into heat. | Like other lighting technologies, LED lighting does not produce only light, [http://en.wikipedia.org/wiki/Thermal_management_of_high-power_LEDs but also heat.] LED technology today is such that only about 30% of the energy going into an average LED is turned into light.

In 2009, Mag Instrument modified the Maglite LED 2-CELL AA and Maglite LED 3-CELL D to each include a better heat sink. Even during extended use, those flashlights now stay at a reasonable temperature without dimming themselves.<ref name="2AA" /><ref>NLee the Engineer (11 September 2010) [http://www.amazon.com/review/R19LDXP4LJKG36 "Maglite second-gen LED flashlight deserves a second chance"].
