The MagBox is compatible with both speedlites and strobes.
When you need more power, the MagBox speedring adapter allows you to mount your Profoto strobe to the MagBox. Made of powder-coated steel, the adapter is super strong and built to last. It attaches magnetically to the MagBox in less than a second. Once it's on, it's not going anywhere until you remove it with the simple press of a tab.
