    Looked a bit at the Arri HMI 5000 Watts. They are very expensive though.
    Would something like this work?

    I can have the lights very close to what I'm filming. About 1 meter away from target so I'm not trying to light a whole room.
    Just did some shots and had to push the ISO to 4000. Ouch a lot higher than I would like, but the final output are very small videos for computer games so thankfully I lose a lot of the noise when I downsample.

    That's a lot of juice. You could not put that anywhere near an actor's face. With a joker 1600 you will get more than enough light to shoot with MX or Dragon with LLOLPF even at rather extreme FPS. It costs a lot less, and has a very small footprint.

    Aha, yea, I think you may be right. Maybe something closer to 1600 or so. Is it the HMI lights you are talking about? They are quite a bit out of my price range. I think my price range is more 1000-2000 dollars. Found some Jokers that cost 10,000.
    Thanks for the help.

    Andreas,

    Id just rent an Arri M18 with a high speed ballast. This can also be fitted with 1200W HMI if too bright. If you need to buy - HMI is well out of your budget range, you may find a tungsten though. They start to get flicker free from 5KW, you may use two 2KW on different power lines, if they are not on the same electrical phase. In general while fresnels provide an excellent light quality they have much lower output then reflectors like PAR or Open Face.

    Cheers,

    Ulf

    I rent most things we use. Joker 1600 is not 10 000 at BnH

    I think Arri T5 would work for this purpose. Its very strong and really cheap to buy or to rent.

    Thank you

    Just for fun, a 220V 30A system that can crank up to 1MW of light output for 10 seconds: http://www.hispeedvideo.de/LSunSource.html

    Definitely a rental...

    Thanks Daniel. Do you think it would be flicker free around 100-300fps?

    Generally a 5K Tungsten globe is fine at higher speeds - the filament doesn't have time to cool between power cycles. That T5 does eat a lot of power; you'll need a 50 amp circuit to make it work. At least here in 60hz 120V land. Probably slightly different in 50Hz 220V land.

    Maybe it could be an idea to get a slightly less powerful one around 2000-3000 watts maybe. What is the biggest lamp that you can operate in normal apartments?
    Cheers

    I read up a bit more and found these Arri ST2 2000W. Were apparently used together with Phantom because they were "flicker free"
