Quick Answer

Attach the Bowens-to-Profoto speedring adapter by first locking it onto your Bowens mount light, then sliding your Profoto modifier onto the adapter's front barrel. This lets you use Profoto softboxes and reflectors with Bowens mount strobes like the Westcott FJ400 or FJ800.

Why Use a Bowens-to-Profoto Adapter?

If you own Bowens mount lights but prefer Profoto modifiers, this adapter saves you from buying a whole new lighting system. It's a precision-machined metal ring that converts your light's mount to accept Profoto accessories. The key trade-off: you add a small amount of extra length to the modifier, which can shift the light center slightly. For most portrait and product work, the difference is negligible.

What You Need

You'll need a Bowens mount light (e.g., Westcott FJ400, FJ800, or L120-B LED), the Bowens-to-Profoto speedring adapter, and a Profoto-compatible softbox or reflector. The adapter features a secure Bowens bayonet lock on one side and a Profoto-sized front barrel on the other.

Step-by-Step Setup

  1. Step 1: Prepare the Light: Turn off and unplug your strobe or LED light. Remove any existing reflector or modifier from the Bowens mount. Common mistake: leaving the light on. Always power down to avoid accidental flashes or pinching.
  2. Step 2: Attach the Adapter to the Light: Align the adapter's Bowens bayonet lock with the light's mount. Push it in and twist clockwise until you hear a click. The adapter should feel firmly seated with no wobble. Checkpoint: if the adapter doesn't click, it's not fully locked. Re-align and try again—never force it.
  3. Step 3: Mount the Profoto Modifier: Slide your Profoto softbox or reflector onto the adapter's front barrel. Push it all the way until the modifier's locking mechanism engages. You should feel a snug fit. Common mistake: not pushing the modifier fully onto the barrel, which can cause it to slip during use.
  4. Step 4: Test the Connection: Gently tug the modifier to confirm it's secure. Power on the light and fire a test shot to check for any light leaks or misalignment. Checkpoint: if you see light escaping around the adapter, the modifier may not be seated correctly. Re-mount it.
