Better Beamer flash extender fitting guide
Find the right Better Beamer Flash Extender for your flash or strobe
To see if your flash is already in our database, try our FlashFinder™.
If your flash is not listed, you can easily measure it to see if one of our Flash Extender models is a good match.
You simply need to measure:
Then select the appropriate Better Beamer Flash Extender from the table below. Here's how ...
Step 1 - Measure flash head height
Measure the height (thickness) of your flash head, at the sides where the Flash Extender arms will clip on.
How height affects fit
The Flash Extender attaches to your flash with two lightweight arms that fit onto the sides of your flash head. These arms have 1/4-inch (6 mm) tabs which wrap around the flash head and help secure the arms and point them in the same direction as the flash. The arms are held in place by our Velcro Quick Attach Strap.
For the best fit, choose a Flash Extender model with spacing between the tabs on the arms equal to or slightly greater than the height (thickness) of your flash head (measured near the edges of the head where the tabs will sit).
If you don't find an exact match, note that
Step 2 - Measure flash head width
Measure the width of your flash head.
How width affects fit
If your flash head is too narrow, the arms will not be far enough apart to hold the Fresnel lens flat. You may be able to correct this with shims. If the head is too wide, the arms will be too far apart where the Fresnel lens attaches, and the lens can't be held in place.
Ideal flash head width also depends on whether your flash head has sides that are parallel, converge, or diverge:
Our new Velcro Quick Attach Strap will easily accommodate a wide range of flash head circumferences.
Step 3 - Check for proper clearance
Ensure that there are no obstructions on the sides of your flash head that could interfere with the placement of the arms.
How clearance affects fit
For optimum performance, the arms should be mounted on the side of your flash so that the bend in the arm is even with the front lens of your flash. This ensures that the Fresnel magnifying lens is held the correct distance from the front of the flash.
Step 4 - Find a matching Better Beamer
Based on your measurements, choose a model from the table:
FX-1 vs. FX-1B: These models are identical, except that the FX-1B includes an extra shim for fit adjustments.
