This little COB light from Viltrox is powerful, bright, solid and smart, eventhough it's very compact and cheap. However, be aware of its main weakness : I mount it with the nanlite PJ-FZ60 projection attachement or a lightdome with the bowens adapter, but it fits very poorly. If I keep it on a stand with the NPF batteries upside down, it doesn't dissassemble, but every other use is too risky. The bowl reflector fits well though, obviously.
