Economy Soft Box Light™ can be used with photoflood, fluorescents, and our new screw-in tungsten halogen lamps. The silver metallic lining inside the soft box is designed for maximum brightness while the diffusion panel provides the smooth velvet light soft boxes are known for. The SBL-1 light fixture has a ceramic socket that will accept all Edison base lamps. The light stand adapter will fit 5/8" light stands. The stand mounting bracket features an insulated handle on the tilt mechanism and a ratchet locking system. The elastic collar on the back of the soft box allows for easy setup and prevents light leaks. You can also use the SBL-2432 24X32 inch soft box on your Smith-Victor FLC200 and FLC300 constant color monolight by replacing the continuous light mounting bracket with Smith-Victor mounting bracket #670159.(Options for tungsten halogen lamps with an Edison screw-in base include the 150-watt JT120V-150 (part 408091) and the 250-watt JT120V-250 (part 408092).
