Also You try for better results halogen 400W bulb (is powering from 36V).  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 10-22-2006 06:52 PM                     The EVD bulb is the 400 watt halogen requiring a 36 volt transformer to operate. You build a support rod to mount the halogen filament in the same spot as the carbon arc point to allow the reflector to do the job. The bulb can run on A.C. but last longer on a D.C. power supply. Wittner Cine in Germany has transformers, sockets and other items to do this conversion.  |  IP: Logged Dave Ritchie Film Handler Posts: 65 From: Thames, New Zealand Registered: Oct 2006 posted 10-26-2006 01:05 AM                     thank you It's all ordered and on it way  |  IP: Logged
