just found the head i was using last summer:

had no idea they were that expensive - but yeah, they are fairly decent for a generic light source... and they were "cold" so i didnt burn my forearms as much! Although i was taking shots on a table top and had a lot of flexibility as to how close the lights could get to the objects i was photographing (it was for a company that sells things on eBay) - not sure how they would fare 4 metres away from a model...

Man is the dream of the Dolphin"
