HID is, in my opinion, the only way to go. I am in favour of the UK HID because of the price. They are waaay cheap compared to other units on the market. The diffuser they supply for video is, quite simply, crap. They should have supplied an optional video reflector.
The diffuser scatters the light too much, and you lose a lot of the light generated by the HID element, a reflector would give even lighting but concentrate it on the subject. This is most important when you are dealing with a HID element of so little power.
If you get close to the subject and have two of these puppies, you have a good lightweight system.
I use a pair of Kowalski 24W HID units, the Xenon's. They weigh in at 600GBP each or about 850USD.
The dogs bollocks.
