;MCPCB: Metal | ;MCPCB: Metal Core Printed Circuit Board. This is the type of board on which LED's are usually mounted. They are metal to help transfer heat and are then attached to a pill or heat sink. Sometimes called a "star" or just a "board." | ||

;P60 drop-in: an assembly of the reflector, bulb, and driver originally introduced by [[SureFire]], but now an industry standard.

;PCB: Printed Circuit Board. A circuit board with electronics soldered to it. Usually it has a plastic base printed with ink, solder pads, and wire paths, but MCPCB's have a metal core. | |||
;pill: a housing for the driver and a mounting point for the LED. In smaller lights it is threaded on the outside and screws into the throat of the flashlight body. | ;pill: a housing for the driver and a mounting point for the LED.

;showerhead: a flashlight with a cluster of low-powered LED's. Generally these are very inexpensive lights (9 LED's seems common), but some have hundreds of LED's and actually give off a decent amount of floody light. | ;showerhead: a flashlight with a cluster of low-powered LED's.

;SinkPAD: a brand name of LED MCPCB that is designed to conduct heat away from an LED more efficiently than typical boards, therefore keeping the LED cooler, increasing brightness and LED life. | |||
;SMD: Surface Mount Device - most high-power LEDs used in flashlights are mounted this way where legs of a component (LED, capacitor, resitor, diodes, etc.) are soldered to pads on the surface of the circuit board (as opposed to through-hole soldering where the legs of the LED's go into holes on the circuit board which are then soldered on the underside with the excess leg length clipped off). | ;SMD: Surface Mount Device - most high-power LEDs used in flashlights are mounted this way where legs of a component (LED, capacitor, resitor, diodes, etc.) are soldered to pads on the surface of the circuit board (as opposed to through-hole soldering where the legs of the LED's go into holes on the circuit board which are then soldered on the underside with the excess leg length clipped off). | ||
