Aluminium and polycarbonate Bowens 139 mm speedring insert, low-profile silver ring

Glow Edge

Glow Edge Low Profile Speedring Insert for Bowens 139mm

SKU CH-W837-40KJF

A low-profile 139 mm speedring insert for Bowens mounts that reduces flashtube-to-modifier distance for better light spread and heat management

  • Low-profile design minimizes light-source distance for efficient output
  • Robust aluminum and polycarbonate construction withstands demanding studio use
  • Compatible with Bowens mounts and Glow EZ Lock systems
  • Quick, effortless mounting saves valuable time during photoshoots
  • Secure, wobble-free connection ensures consistent, precise light shaping

Purpose and Fit

The Glow Edge Low Profile Speedring Insert connects Bowens-mount flash heads to Glow EZ Lock modifiers. It is built for photographers who need a secure, low-profile link between their light source and softbox or reflector.

Critical Specification

The insert measures 139 mm across and matches the Bowens S-type mounting pattern used on heads such as the Flashpoint XPLOR600 series. Without this exact diameter and mount style the modifier will not seat correctly.

Thermals, Noise and Power

The all-metal and polycarbonate construction dissipates heat from the flashtube without adding active cooling, so there is no fan noise. By reducing the gap between tube and modifier it helps prevent overheating during extended sessions.

Questions about this item

How does the 139mm diameter affect modifier fit on a Bowens mount?

The 139mm size matches the Bowens S-type standard so softboxes and beauty dishes with interchangeable speedrings lock on without gaps or adapters.

Which flash heads does the Bowens-compatible mount actually support?

It fits any Bowens S-type head including the Flashpoint XPLOR600 series and serves as a direct replacement for the Bowens RD-6210 adapter ring.

What clearance does the low-profile design add between the monolight and the modifier?

The insert sits close to the flash head to minimise the distance between the flashtube and the softbox, improving light spread and reducing heat buildup.
