This is the Westcott Spiderlite TD3 Backlight Kit which is based on the Westcott Spiderlite TD3 light fixture. The TD3 accepts three 50 watt tungsten (2800° K), three 30 watt fluorescent (5500K) bulbs, or two Studio Strobes and one modeling light.
This kit includes a diffuser dome which is useful in directing and softening the light emitted to your background. It also doubles as a tube protector during transport and storage.
The Backlight Stand rises to a maximum height of 3' (0.9 m). The riser is detachable, thus allowing your fixture to be mounted almost at floor level.
The TD3 has all-metal construction with built-in points for direct attachment of a 12 x 16" softbox -- no adapter ring is necessary (For mounting larger or octagonal softboxes, order #3520 Adapter Ring).
