From the Manufacturer:
The Spiderlite TD6 is the most powerful and compact constant lighting system available today. This durable unit is perfect for on-location or in the studio offering up to 1200 effective watts of power per light. The Spiderlite TD6 offers the ability to switch between cool daylight fluorescent lamps to Tungsten Halogen hot lamps. Be prepared for any situation with one light head that can offer both options! Three separate controls allow the ability to adjust light output, without changing color temperature. With an adjustable rheostat, every time adjustments are made, color temperature can shift greatly. By utilizing these switches, your color stays constant which means you are only white balancing your camera once! Each switch controls 2 lamps.
Other features include:
All metal construction.
The Spiderlite TD6 is constructed of all-metal, no plastic to break.
The surface was intentionally designed to be highly reflective maxizing light output. Any light that is projected back towards the light base is bounced off the silver surface and projected forward for maximum efficiency.
Built in adapter ring.
No need for additional brackets as this unit incorporates a built in adapter ring. Simply insert the soft box rods into the four openings. For easier set up, one softbox rod insertion point is cut out at the top. This allows the last soft box rod to simply slide into place.
Using the oversized handle and lock-down turn knob, rotate the light head 180-degrees and turn your softbox from a vertical to horizontal position in seconds.
15 ft extra long power cord.
No need for additional extension cords as this unit comes standard with an extra long 15' power cord.
Included tilter bracket.
The included tilter bracket allows the Spiderlite to be tilted to precise angles.
Power the unit on and off through the UL-approved heavy duty cord switch.
