LitePanel Astra 4x
The LitePanel Astra (4x) has been a workhorse 1x1 in on set lighting for years. Being light weight you can put it pretty much anywhere for bounce or directional light, through a chimera or through a roll of diffusion. The possibilities with this light or endless.
The Astra is not RGB, but is bi color between tungsten and daylight and is fully dimmable. You can power the Astra through shore power or power it through the V mount plate and dtap cable on the back.
