The Ultimate Light Box is the only Flash Diffusion System!
The Ultimate Light Box flash diffuser is a system of individual components designed

to be used either separately

or in combination with one another.

Our Ultimate Light Box system begins with our custom fit Flash Adapter/Diffuser.

Our flash adapter is a laser cut adapter that attaches securely to your specific camera flash without the use of rubber bands or Velcro. Slide it on and off easily and quickly while shooting on the go!

Next, snap our bounce diffuser dome onto the adapter for a soft diffused light.
Thanks to our larger domed design, the light spreads more evenly and over a wider area than other small flat diffusers. With one snap, you can enlarge the diffusion area of your flash.




The Ultimate Light Box System is designed to be used as a bounced, a direct, or a reflected flash diffuser or in combination together to deliver an even, soft light.

The second component is the Ultimate Light Box and Diffuser Lens.

Made of durable light weight plastic that attaches easily and securely to the smaller bounce diffuser our Light Box enlarges the surface area of the flash up to 700%!  The Ultimate Light Box Kit also includes two additional Lee™ flash diffusion filters that mount inside the flash diffusion lens and add additional softness.Only the Ultimate Light Box allows you to shoot direct.  Add more or less flash diffusion or control the direction and the intensity of the light, to capture the perfect image.

The Ultimate Light Box System is the only flash diffuser to give photographers complete control of the lighting.

The third component is the Large Reflector that attaches to the Ultimate Light Box and reflects additional light forward.
Most flash diffusers, including the Ultimate Light Box, have a 360 degree angle of coverage. A typical 35mm FF lens has a picture angle of 62 degrees while a 35mm DX format has a picture angle of 44 degrees. Light that is directed outside of the angle of your lens is basically lost except for reflection. The Ultimate Light Box reflector directs a large amount of that lost light back toward the subject. Also available is our Mini Reflector that mounts internally and may be purchased as an accessory.

The Ultimate Light Box System may be used in any combination of ways:
  • with the small dome attached or not
  • with the large diffusion lens on or off
  • with or without the diffusion filters
  • with or without the reflectors attached
  • or any combination together!
    When the system is used together, the inner dome performs like the inner baffle in a studio soft box and reduces hot spots from the flash. The system is limited only by your imagination and allows you to control the amount and softness of the light as you desire.

        And.....It's more compact than you'd imagine!
    The Ultimate Light Box System stores easily in your camera bag either slipped over a lens or with your camera flash stored inside of the light box.

    "Over the years I've tried any number of light modifiers. None that I found ever improved on simple bounce flash. I only used them when bounce was impossible or impractical. This product is different. I can't think of any situation that requires flash that wouldn't benefit from using the Ultimate Light Box." - T633 from Dover, NH
