This 21 x 19" MixPanel 150 Softbox from Nanlite is compatible with the MixPanel 150 LED Panel. It features a speed ring-free design and the unit mounts to the front of the LED panel via touch fasteners. Ideal for portraits and interviews, the softbox reduces contrast while diffusing the light, and the included grid gives you added control over the spill light. The softbox folds flat for easy storage, and a carry bag is included for transport.
