New higher power lighting rig

This is a conversion of my  lighting rig to power three Xlamp LEDs as studio lighting, each channel using 2-3A and delivering about 20 Lux to a screen at 3m (without lens).

This is the kind of power I need to illuminate a screen and still be able to shoot video at ISO6400 or pref well below that.

That way I could shoot a realtime shadow play on a 3x2m screen using an effective point source.  The sgadows will stay sharp even some distance from the screen and the shadowplay can take place in a 3D cone of light.

Portable LED lighting box

3 (opt 4) channel constant current LED driver with potentiometer current adjustment for control of LED torches, possible installation lighting.  Based on RECOM LED driver – data sheet below.

Makes the much larger studio rig portable – I can take this around and work out of the studio, on a small scale.
