;<span id="FET">FET</span>: field effect transistor. Basically a digitally controlled switch, these are used in high current [[driver|drivers]] offering less resistance to current than other designs and therefore higher output. | ;<span id="FET">FET</span>: field effect transistor.

; | ;<span id="flood">flood</span>: scattered light emitted from a flashlight. Good for indoor use to light up a room or short-range use outdoors to light up an area. Compare with [[#throw|throw]]. | ||

;<span id="forward">forward clicky</span>: a switch that turns the light on with the button partially depressed and then locks into on once it is fully depressed and clicked. This allows "momentary on" by halfway depressing the switch and then releasing to turn it off. A forward clicky is not as good for switching modes. Compare with [[#reverse|reverse clicky]]. | ;<span id="forward">forward clicky</span>: a switch that turns the light on with the button partially depressed and then locks into on once it is fully depressed and clicked.

;<span id="Forward Voltage">Forward Voltage</span> (a property of an [[LED]]). The voltage drop across a LED at a given current. If two LEDs are identical except one has a lower Vf, the one with the lower Vf will draw a higher current from a battery and will also be brighter. | ;<span id="Forward Voltage">Forward Voltage</span>: (a property of an [[LED]]).

;<span id="spill">spill</span>: the area of a flashlight beam outside of the hotspot and corona. Light intensity in the spill area is typically low and even, and comes directly from the light emitting surface with little or no contribution from the reflector. | ;<span id="spill">spill</span>: the area of a flashlight beam outside of the hotspot and corona.

;<span id="spring bypass">spring bypass</span>: a modification to the battery springs in a flashlight to reduce resistance and increase current. The typical spring bypass involves soldering braided copper wire from the tip of the spring to the base where the spring attaches to the switch and/or driver. | ;<span id="spring bypass">spring bypass</span>: a modification to the battery springs in a flashlight to reduce resistance and increase current.
