  • Just buy it
Model: FJ400 II Single Light
This thing is a beast! Lit in a small room with no diffuser, just bounced off the ceiling. I just upgraded from a Goddox ad200 and I’m so happy I took the leap.

Love the product but when I order Amazon it needs to come to my house not the dang post office. If I wanted to leave my house I would have went to the store to purchase.
