The Medalight PG20W Wide Angle Slave is a simple slave flash, designed to trigger with any initial burst of light (and thus incompatible with evaluative preflash metering systems), that installs into any standard household lightbulb socket. Its wide dispersal area allows its light to completely fill a lamp shade, creating natural-looking, daylight balanced room background light.
