The Westcott 1200W Spiderlite TD6 7' Parabolic Umbrella Kit is a great illustration of how much you can do with a single light source. The kit includes a Spiderlite TD6 lamp head, a Tilter Bracket, six 50W, 220V daylight fluorescent lamps, a 7' Parabolic Umbrella with silver interior, carrying case and a front diffuser.
The silver 7' Parabolic Umbrella is a really big, broad light source that wraps light around your subject yielding clean highlights and rich open shadows. But due to the special shape of the umbrella there's a unique mix of soft enveloping light with the kind of crisp detail you only get from reflectors.
The shaft is double walled for strength, but it tapers to 7 mm to fit Elinchrom and other European flash heads. The silver interior is slightly cooler in color temperature than a white umbrella and tends to focus the light into a soft but narrower field - ideal for throwing the light over a long distance. Two of them, for instance could light an entire auditorium or a large graduating class. Mounting the front diffuser on the umbrella produces light reminiscent of a large octabox.
The TD6 lamp head accepts 6 (included) 50W daylight-balanced fluorescent lamps, rendering an accurate, full spectrum output with a CRI rating of 90+. Three switches on the lamp head allow you to use 2, 4 or 6 lamps to control power level. All-metal construction and built in adapter ring with 180-degree rotation make the TD6 a favorite of photographers and videographers alike.
