which clamp to fix an HID video lamp to the arm

[stargost]

I have a standard (Ligth Monkey / Salvo) 21W canister ligth with a video diffuser and was trying to get it fixed to the camera, but what i've done so far hasnt worked well.

Is there a standard accessory which would clamp the ligth head and make the connection to the arm (I have sea and sea, but i guess the it doesnt matter

Thanks a lot
