The Westcott Window Three Light Plus Kit 2100 is based on the Spiderlite TD5 and TD3 light fixtures, which accept fluorescent (5000° K) or tungsten (2800° K) bulbs, or screw-in strobes. Although this kit is rated at 530 total fluorescent watts, it puts out the equivalent of 2100 watts tungsten, according to Westcott.
Three separate controls on the TD5's allow running of multiple combinations of bulbs together with no color shift.
The TD3 accepts three 50 watt halogen (available separately) , or three 27 watt fluorescent bulbs. It can also run two optional screw-in AC strobes with one modeling light. It is also capable of running on DC power with an optional inverter and battery. Each fixture in this three light kit has all-metal construction with built-in points for direct attachment of a softbox -- no adapter ring is necessary.
This Three Light Kit includes two 24 x 32" and one 12 x 36" silver interior softboxes, tilt brackets, 50, 30 watt and 20 watt screw-in fluorescent bulbs, three 10' heavy duty light stands, a boom arm with counterweight, and a deluxe wheeled case for storage and transport.
