They all are painted to look like ARRI units but of course they're not. Has anyone actually tried any of these lights? The ebay store is called Seven.Studio

From the outside the heads look almost the same, although the finishing is not as "perfect" as the one of the originals. The ballast is a bit different but the functions are the same (stepp-less dimmer etc). We had some problems with the ballasts, some we´re getting really hot, others we´re quiet noisy, but not all of them! Most of them worked quiet fine.
I compared the beam and by watching it (did´nt measure it because I never had the time at work) I could see a difference in the grade of it at the points where the fresnel glass "makes a step" (don´t know how to call this - i mean the typical fresnel structure with "stairs"). The Arri glass is much better, the grades are softer and it´s like one beam of light whick looses intensity towards the edges, the chinese glass looks more like layers of light with different intensities. Maybe it has got to do with the mirror too. Both lamps were equipped with the same, brand-new Osram HMI-lamp!
Anyway. It seems that Arri has got some quality problems too. The rental house ordered a couple of brand new 6K-PAR Arri Heads with Ballasts in the States and two of them did´nt work, they had a problem with the electronics and it becam necessary to exchange the whole board of the ballasts. From the inside they look like a computer...
By the way. There is a local brand called "Dexel" which copies a lot of lamp heads too, mainly fresnel units and some of the look exactly as "Desisti" studio lights. I always wonder wether this brands are getting any problems with copyright and patents...
