;<span id="ramping">ramping</span>: a mode in some flashlights where the brightness varies (ramps up or ramps down) and you select the brightness level you want. Sometimes this level is then memorized, but in the original [[NiteCore]] D10 it is only used until you turn the light off again. | ;<span id="ramping">ramping</span>: a mode in some flashlights where the brightness varies (ramps up or ramps down) and you select the brightness level you want.

;recoil: or "recoil thrower" is a flashlight design where the LED is mounted on an arm just under the center of the lens, facing backwards into the reflector. Such a light can produce a very intense hotspot with great throw and very little spill. One downside is there is not much heatsinking to carry heat away from the LED. | |||
;regulator: in a flashlight, a circuit that takes energy from a battery and converts it to a (usually) constant current or voltage to feed the flashlight's light element (either an LED or bulb). Using a regulator, the flashlight's brightness usually stays constant for the majority of the lifetime of the battery, and then output drops quickly and significantly as the battery is no longer able to supply the required energy. Non-regulated flashlights (also called direct-drive) usually start out at a high output, and then the output diminishes gradually over the lifetime of the battery.
