5.0 STROBE BRIGHTNESS
The strobe’s brightness depends on how wide the LED flash pulse is; the wider
the pulse, the brighter the visual output from the LEDs. Since the strobe is
primarily used on reciprocating or rotating targets there is a downside to the
wider flashes. All strobes work by giving short bursts of light (the pulse width)
at a rapid repetition rate (the flash rate). Strobes rely on the persistence of the
