Speedlight is the brand name utilized by Nikon Corporation for their photographic glimmer units, utilized since the organization's presentation of strobe flashes in the 1960s. Nikon's independent Speedlights (those not incorporated with the organization's cameras) have the SB-prefix as a major aspect of their model assignment. Current Speedlights and other Nikon extras make up some portion of Nikon's Creative Lighting System (CLS), which incorporates the Advanced Wireless Lighting, that empowers different Nikon cameras to control numerous Nikon streak units in up to three separate controlled gatherings by sending encoded pre-streak signs to slave units.
Nikon's rivals like Canon and Ricoh utilize the comparative name Speedlite for their flashes. The two names demonstrate that strobe flashes deliver significantly shorter and more serious blasts of light than prior photographic lighting frameworks, for example, flashbulbs, or consistent lights utilized as a part of some studio circumstances.
