Impact Luxbanx Duo Large Square Softbox (40 x 40")
Key Features
  • For Strobe, LED, Fluorescent Lights
  • Also Compatible with Quartz Lights
  • Maximum Quartz Wattage: 1500W
  • Heat-Resistant Textured Silver Interior
The Luxbanx Duo Large Square Softbox from Impact is a versatile 40 x 40" light-shaping tool for strobe, LED, and fluorescent lights. It has a heat-resistant, textured-silver interior so you can use it with quartz lights up to 1500W. When using the Luxbanx Duo with strobes, attach the front diffuser and inner baffle for maximum softening of the output. When using it with hot lights, the inner baffle should be removed. Open face lights can be used as is, but it's recommended that you use the flood setting rather than spot on Fresnel sources. The softbox has four forward-opening vents to dissipate heat. Removing the front and inner diffuser essentially turns the Luxbanx Duo into a large reflector with maximum brightness and contrast.

Impact Luxbanx Duo Overview

The Luxbanx Duo Large Square Softbox from Impact is a versatile 40 x 40" light-shaping tool for strobe, LED, and fluorescent lights. It has a heat-resistant, textured-silver interior so you can use it with quartz lights up to 1500W. When using the Luxbanx Duo with strobes, attach the front diffuser and inner baffle for maximum softening of the output. When using it with hot lights, the inner baffle should be removed. Open face lights can be used as is, but it's recommended that you use the flood setting rather than spot on Fresnel sources. The softbox has four forward-opening vents to dissipate heat. Removing the front and inner diffuser essentially turns the Luxbanx Duo into a large reflector with maximum brightness and contrast.

For additional control, the versatile Luxbanx Duo has an optional fabric grid which mounts to the recessed lip of the softbox with touch-fasteners. The grid narrows and concentrates the light's beam forward, controlling spill light and adding directional control to the Luxbanx Duo's attributes. The ample surface area and square shape of the softbox make it ideal for large sets, groups, full length fashion, and large product work. Every Luxbanx comes with a carrying case and a spare Flex Rod. Separate purchase of a speed ring that accommodates your light's mount is required for use. Impact makes models to fit most popular brands.

When paired with the Arri Brand Lighting it's perfect. These soft boxes are big and heavy and made for hot lights.

Asked by: Noah
You can use it as long as you buy a Bowens Mount speedring -- i.e. Impact Speed Ring for Impact, Bowens S, Westcott . Then it will mount perfectly.

question

Will this work with Bowens S Mount?
Asked by: Tim
Yes; if you purchase the Impact Speed Ring for Impact, Bowens S, Westcott & Aputure, B&H # IMSRIMPV2, it would allow you to use the Impact Luxbanx Duo Extra Large Rectangular Softbox (54 x 72 ), B&H # IMLBRDXL, with a light fixture that has a Bowens S-mount for light modifier usage.
