With a guide number of 190', the MS300-V Studio Flash Monolight from Godox is a 5800K flash source that replaces the original 150W halogen lamp model with a 10W LED modeling lamp that draws very little power with great brightness. It features a 0.1 to 1.8 second recycling time with flash durations as short as 1/2000 sec. Power is variable from 1/32 to full power while the 10W LED modeling light is adjustable from 5 to 100%. Triggering options include sync cord, optical, test button, and wireless power control. The MS300-V is ready to run on 110 to 120 VAC mains power.
