The Alpha Speedbox is a new line of softbox from SMDV designed for use with monolights.
Designed to withstand the heat generated by modeling lights, the Alpha Speedboxes are based on speedrings made with aluminum and steel rods. As with the non-Alpha Speedbox's speedring, the Alpha Speedring features SMDV's patented folding mechanism.
Also, the Alpha Speedring has larger opening to be able to accommodate all kinds of monolights, including Profoto.
Various mounting adapters are and will be available, including Alien Bees, Bowens, Elinchrom, Profoto, and more!
