Phottix designed the Barndoors with Grid and Gel Set for the Indra500 and Indra360 TTL monolights. This kit includes four-way barndoors, a 60-degree honeycomb grid, a set of red, yellow, blue and green gels, and a carry bag. The honeycomb grid helps control light spill and adds directional control to the output, which can be further directed by using the barndoors. The kit can be used with or without the barndoors, and the coloured gels offer creative options for edge lighting or background lighting.
