This is an Interfit Stellar Tungsten Two-Light Twin Softbox Kit. It includes two 24x24" softboxes with adapter rings, two 500W bulbs, two 8' (2.4 m) air-cushioned light stands and a padded kit case with interior dividers.
Stellar Tungsten units have tough aluminum bodies built for long life and reliable service. The 500W bulb is color balanced to 3200°K enabling it to be used with other Interfit products such as SXT3200 or halogen lighting.
The Stellar Tungsten units feature "S"-type bayonet fittings enabling the use of Stellar light modification accessories such as softboxes, or a beauty dish for portraits and fashion images. The use of honeycomb grids, color gels and snoots is not recommended as these will shorten the life of the lamps. Interfit recommends the use of 400 ISO when using continuous lighting.
