Capture breathtaking scenes and perfect images while in motion with a high-speed strobe driver module from LEDHOT LIGHTING COMPANY. One of our best sellers is the SP-600-DC Series that is compact but a little larger than SP-300-DC. Like the SP-300-DC, this unit has a built in Over_Temp cutoff feature, and also has internal cooling to keep you shooting. When attached to a camera via hot-shoe, this strobe driver is a workhorse that won't quit.
