The Diva-Lite 401 puts out a broad soft wash of light with drop off similar to that of a bounce card / reflector. For this reason it is most effective in close proximity to the subject. The built-in barndoors and detachable louver provides control over the spread of the light. For an even softer light, you can use the 1-stop flozier diffuser. It’s fitted with four Kino Flo True Match 55W 5500ºK compact fluorescent lamps, providing ample light for a quick interview setup with a single light. Light level control is established through an onboard dimmer as well as by 2 and 4 lamp switching, with an attached in-line power cord.
