Where is the rub? They look great but why so cheap? I am now investigating . . .
I'm skeptical of these lights since it takes three bulbs for any kind of power, though I also question the power of HMI's in general.
I rent 2.5k Arri Fresnels all the time and running two or three usually soft bounced into either book ends or through a 4x or 12x rag and using a medium format back at 200 iso puts it right on the limit, like 1/60th at 5.6, where as with a dslr I can bump it too 640 and hold it.
Sill I don't really believe that HMI's produce 2x 3x the power of tungsten, as I've used both in the same setting and at the close to the same wattage didn't see much difference.
Also if working in a blacked out studio or location without window lights, I like the look of tungsten vs. HMI. New hmI bulbs are very blue and i find difficult for skin tones and though everyone says tungsten destroys the blue channel I've yet to see it do anything but look pretty, so I don't know.
These were shot with the 1ds3, not a lot of movement, obviously, but still shot at a fairly high iso and quick enough shutter and dof to work with a 1k. The top image was a fresnel, with a little bit of spun, the bottom was diffused through a box and flagged.

The earlier Canons had a difficult time going to a low enough Kelvin, not to have a lot of orange to the file, where the p30+ was beautiful with tungsten, though now the 1ds3 goes to tungsten quite easily.
Still, I'd like to see how these hid lights work, because the price looks good, I just wonder at this price if they are really usable and will work long term.
Personally, I don't think any of these smaller hot lights work well with people that are moving at any moderate speed, unless you use a Nikon at 1000 iso and then it's iffy.
I would like to see higher pixel cameras with higher iso and moderate powered (and priced) continuous lights that would work both with stills and motion.
We'll see.
