For image-makers in the field without access to AC power, the Forza 60 Battery Grip from Nanlite is an ideal, ergonomic solution that is designed to balance the light even with the optional FL-11 Fresnel or a softbox attached. The grip accepts one V-Lock type batteries that will run the 60W light for up to one hour half to five hours depending from capacity of battery. You can stand-mount it via its 5/8" (spigot 16 mm) or handhold it for the ultimate freedom of movement.
