Impact Luxbanx Extra-Small Deep Octagonal Softbox (18")
Key Features
  • 12" Deep Parabolic Design
  • White Interior
  • Spare Rod
  • Removable, Recessed Front Diffuser
The Luxbanx Extra-Small Deep Octagonal Softbox from Impact is a highly versatile tool for strobes, LEDs, and fluorescents. This extra-small 18" diameter softbox allows photographers to pinpoint a light source to separate a subject from the background and is well suited for controlling light placement for close-up head and shoulder poirtraits while retaining the wrap-around light and circular catchlights created by larger octaboxes. Also, this model utilizes a 12" deep parabolic design that provides a long throw and directionality that is great for portraits and minimizes light spill. The softbox features a soft white interior, removable front diffuser and removable inner baffle. The diffuser and baffle can be used together for maximum softening of the output. Removing the inner baffle will give you a more crisp light quality with higher contrast, while shedding the front and inner diffusers turns the Luxbanx into a large reflector with maximum brightness and contrast.

Impact Luxbanx Overview

The Luxbanx Extra-Small Deep Octagonal Softbox from Impact is a highly versatile tool for strobes, LEDs, and fluorescents. This extra-small 18" diameter softbox allows photographers to pinpoint a light source to separate a subject from the background and is well suited for controlling light placement for close-up head and shoulder poirtraits while retaining the wrap-around light and circular catchlights created by larger octaboxes. Also, this model utilizes a 12" deep parabolic design that provides a long throw and directionality that is great for portraits and minimizes light spill. The softbox features a soft white interior, removable front diffuser and removable inner baffle. The diffuser and baffle can be used together for maximum softening of the output. Removing the inner baffle will give you a more crisp light quality with higher contrast, while shedding the front and inner diffusers turns the Luxbanx into a large reflector with maximum brightness and contrast.

The octa Luxbanx has an additional control via the 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 and adding directional control to the Luxbanx's attributes. The large surface area of this octagonal-shaped softbox gives you a unique wrap-around quality of light that gains emphasis as you move it closer. Catchlights in the eyes of your subject are round and natural. Every Luxbanx comes with a carrying case and a spare Flex Rod. Separate purchase of a speed ring that matches your strobe's mount is required for use. Impact makes models to fit most popular brands.

Impact Luxbanx Reviews

Quality Softbox

By Craig Richard
Rated 5 out of 5

I glad that B&H sells these Impact soft boxes that are wonderful for the price. I can only tell you that I was able to build a vast array of light modifiers and speed rings for a faction of the cost from the yester years of the past. CRC

Not the best, but mostly satisfactory

Works pretty well as designed. I don't like the slight yellow tint of the inner baffle, which I don't use anyway because I have bare bulb flash units. I also own an Impact 72 large strip softbox that I bought several years ago and stored folded, which now stinks when I open it, presumably due to some deterioration which I can't see. These Impact softboxes are not as nice as the Chimera ones I have owned, but they are a much better value and are satisfactory.

How does this compare with Aputure's Light Dome II, which is much more expensive?
Asked by: Mark
The Light Dome II is 34" this is 18". This softbox does not have a gel holder or include a speed ring. You will need to assemble this softbox rod by rod where the Light Dome II is on a umbrella shaft.

What inexpensive fluorescent light can be used with it? And what adapter would be needed?
Asked by: Lance
A fixture you may use that can accept a fluorescent bulb is the Photoflex StarLite QL Tungsten Fixture (120-240 VAC) B&H # PHSLFVBSL320. It would need the Photoflex Mogul to E-27 Lamp Adapter B&H # PHFVSKT and then the ALZO CFL Photo Light Bulb (85W, 120V) B&H # AL151255. To attach the softbox, you will also need the Photoflex Speed Ring Octo Connector for Starlite B&H # PHSRSOC. https://bhpho.to/2xm4iqF https://bhpho.to/2DQcgOV https://bhpho.to/2MshD9q https://bhpho.to/2SlOL8e
