The Westcott 1200W Spiderlite TD6 7' Parabolic Umbrella Kit is a huge daylight source with added punch thanks to its silver interior. Imagine welding several beauty dishes together, then add the wrap-around light quality of a really large light source and you have the Parabolic Umbrella. It features a solid metal shaft that tapers to 7mm to fit European type heads like Elinchrom, as well as standard 8mm models. The included bonus front diffuser offers even softer results.
The kit includes the renowned TD6 lamp head and 6 digital-friendly, daylight-balanced, 50W full spectrum fluorescent lamps with a CRI of 90+. Three switches on the light head allow you to use 2, 4, or 6 lamps to control power output. All-metal construction, 180-degree rotation and a built in adapter ring make the TD6 a favorite of photographers and videographers alike.
