Glow Edge Low Profile Speedring Insert 139mm for Flashpoint XPLOR 400/300 Direct Mount

Product identity and audience

The Glow Edge Low Profile Speedring Insert is a 139mm adapter built for Flashpoint XPLOR 400 and 300 monolights. It lets photographers attach modifiers that use interchangeable rear mount disks directly to these strobes. The part is made for professionals who need a secure, low-profile connection on location or in the studio. It is not for users whose lights lack the direct-mount collar or who need a different diameter ring.

What the accessory changes

The insert positions the flashtube at the optimal height inside the modifier to maximise output and spread. It prevents light and heat from being trapped in the mount collar, which otherwise reduces efficiency. The low-profile construction adds minimal bulk, so the modifier sits closer to the strobe body for better balance. Setup is a simple attach-and-detach action that speeds up modifier swaps during a shoot.

Deciding specification

The critical figure is the 139mm diameter, which must match the speedring opening on your softbox or reflector. If your modifier uses a different size disk, this insert will not fit. Confirm the 139mm requirement before ordering.
