Ok thank you all for your response. Does anyone have any specific models or where to start looking?
Also i should have mentioned this earlier but portability is a must. I will be using them traveling overseas most of the time.
If you need light weight AND durability(relative) then LED panels or fixtures are what you need. I would start by looking at the vendors mentioned in American Cinematographer magazine and on various video blogs. As this forum is largely concerned with still imaging, continuos lighting info is scarce from experienced people. Also relevant is how large a space do you need to light?
