The Westcott Spiderlite TD5 light fixture accepts tungsten (3200° K) or fluorescent (5000° K) bulbs. Three separate controls allow running of multiple combinations of bulbs together with no color shift. It has all-metal construction with built-in points for direct attachment of a softbox -- no adapter ring is necessary.
This fixture is available as the heart of several kits that include a softbox, tilt bracket, and light stand. 220 volt AC Bulbs must be ordered separately.
