Kobold

Kobold debuted their Softube, an accessory for their Kobold 200 and 400 Par and Bron Kobold strobes. The Softube is a collapsible light tube that fits onto the front of the fixture and creates a large soft source from an intense source like an HMI Par. The tube comes with a built-in reflector and a Velcro shroud that allows users greater control of their light in the field.
