Comments about Speedotron Speedotron M11/CC Light Unit - 1600WS with 11.5" Reflector and 5500°K color-corrected flash tube:

I bought three of these in 1987-they ALL still work perfectly. Very versatile. Uses either Brown Line OR Black Line Speedotron Universal Mount reflectors and accessories in 7,11.5,16,20, or 22 inch (Black Line beauty dish). Allows use with barn doors,honeycomb grids,diffusers,and colored gels. Works well with softbox speed rings and Lastolite Umbrella Box and other umbrellas with 7 inch reflector attached. Durable flash tubes,powerful modeling lights. The best Brown Line light head for heavy use.
11.5 inch reflector with Speedotron 20 degree grid + snap-on diffuser+ 2 Leaf barndoors makes a superb hairlight or separation light
