I was taking a look to some key lights and I was trying to understand weather
it would be possible to build one of this kind of lights on your own:

http://www.arri.de/lighting/europe_...mpheads/arrilite_open_face/arrilite_2000.html

I noticed on the tech specs:

Power: 2000 W Lamp Type: P2/27 FEX 2000 W 230V RX7s
i googled and this among others came out:

http://www.illuminoservice.it/italiano/dettaglio-prodotti.aspx?id=964

which costs just 22 €.

now is it possible to make your own light saving so much?

I mean, is really that kind of bulb, lamp, that is mounted on that Arry?

what else should I care or should I look for when trying to build one of those on my own?

ps: i noticed one thing i ma concerned about:

The globe is an expendable item and a very small part of the fixture. There are several manufacturers for fixtures of this type, but even the most efficient re-interpretation of that Arri is only perhaps 20% or 30% less expensive.

The one I have not used is Impact, so I cannot speak to their quality.

BHPhoto continuous flood lighting.
 
I don't recommend a diy starting around a bulb that hot. Open face tungsten fixtures are reasonably priced enough to be not worth the bother. If you want to mess around get a work light and try to come up with a better reflector for it, that is the starting point and the fundimental difference between film lights and shop lights.

DIY energy is much better spent on florescent. the commercially available 5000k daylight tubes whether long tubes or screw in compacts white balance very well. a 2x4' shop light and a sheet of sign board plastic will make you a pretty good kino knock off. get some basic clamp scoop reflectors for the compacts and you are golden.
