I mounted the two Spring Grip Clamps on to the seat backs of two chairs. In the clips I mounted Nikon Speedlight SB-80DX and directed them against the white wall.
我将2只大力夹夹在了2个椅子的后面，并且在夹子上安装了SB-80DX，直射背景墙。

No power pack or springclips needed, it works off a 9v battery.
不需要电源或弹簧夹子，仅需要9 V的电池即可。

The power to them being changed should be shut off, the springclips and aluminum braid released, and the old removed.
