Questions & Answers

Murat K : Do I need an adaptor to connect this to an AD200 with barebulb?VALERIE B : No adaptor needed. I use it with a Godox AD360II which has a bare bulb similar to the AD200. This will fit over the bare bulb then twist to lock.
JAMES R : Does this fit AD200 Pro with bare bulb?MARIO M : yes it will fit the ad200
Shopper : does this octa come with a grid?

Excellent product!

Quality materials. Very quick to assemble. Surprised to see that the mount now has a Godox - like slot, given that Godox borrowed the design from Quantum. Fits my AD200 perfectly.

Quantum QFlash softbox.

The Quantum softbox is perfect for the QFlash. It is very portable, very, very easy to set up and creates a nice effect.

You will not be sorry, this softbox is perfect

I use this small softbox with my Lumedyne light system both outside and inside my studio. Ive gone through several in the past ten years of the kind Lumedyne offered and they stopped selling it and steered me to this one that Adorama sells. It's better engineered and has better materials then what I was previously using and overall I LOVE, LOVE, LOVE it. And the price is very reasonable for what you are getting too. Wholeheartedly recommend.
