Canon Speedlite 188A Flash With Case
-Takes 4 AA batteries.
-Comes with case.
Speedlite is the trade name for Canon's line of external flashes for use with their EOS line of cameras. It is similar but not to be confused with Nikon Corporation's "Speedlight" brand for their flashes. The Speedlite name is also used by Ricoh for its unrelated product line of flash units, such as the Ricoh Speedlite 202.
The brand names are intended to indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or the continuous lighting used in some studio situations.
