The Super Pro Plus is designed for use with a strobe, with fabric not intended for the heat of a continuous light. Because of its small size and white interior, light quality will be soft and even.
The 12x16 size is ultra portable and lightweight. It can be taken on location easily. The "Plus" designation of this softbox means you can remove the front face of the softbox if you like.
Chimera makes different strengths of diffusion material for front face applications. The softbox comes with a one stop diffuser, but a 1/2 or 1/4 grid cloth can be purchased separately. These would allow more light transmission and less softening of the light.
