1. A medical device, comprising:
a head comprising a light source; and
a handle coupled to the head, the handle comprising:
a battery configured to supply a voltage to the light source;
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
receiving an indication associated with adjusting an output of the light source; determining an amount of current drawn by the light source from the battery;
determining, based at least in part on the amount of current drawn, that the light source comprises a Halogen light bulb or a light emitting diode (LED);
determining, based at least in part on determining that the light source comprises the Halogen light bulb or the LED, a threshold amount of time;
determining that the threshold amount of time has elapsed since the battery has supplied the voltage to the light source; and
causing, based at least in part on the threshold amount of time elapsing, the light source to be disabled by disconnecting the battery from the light source.
