The Lightsock 80 is a covered wagon style diffusion system made specifically for the Astera Hyperion tube. When used without the included blackout “siders” it will provide 360° of beautifully diffused light. The diffusion comes by way of proprietary material known as “Pearelescent” by the manufactuer. Adding 1 “sider” and you can reduce the aperture to 180°. Add the second to reduce the aperture even further. Access the back of your Hyperion through the provided cutouts with your fingers or clamp of choice.
