Author Topic: 6kw GS/7kw GS - Possible? Andrew McCrea Jedi Master Film Handler Posts: 645 From: Winnipeg, Manitoba, Canada Registered: Nov 2000 posted 01-09-2005 10:44 AM                        This might sound like a stupid idea, but is there any chance that the xenon bulb manufacturers will begin developing 6000 watt or 7000 watt GS/GTP bulbs that could output up to 10,000 watts of light? It seems that with exhibitors now using 60-80 foot wide screens, with low light, such an invention might be useful. They've recently developed the 2000-3000 GS/GTP bulbs. Anyone want to explain why this might not be possible or why it could be a good improvement? I assume that the bulbs would not have a long life. Thanks!  |  IP: Logged Aaron Sisemore Flaming Ribs beat Reeses Peanut Butter Cups any day!

The upper limit for 35mm film without damaging it is 7K. I would assume that '10K of light from a 7K bulb also includes all the IR that comes with the visible. No go. The real solution to these giant screens is , of course 5/70 film! -Aaron  |  IP: Logged Andrew McCrea Jedi Master Film Handler Posts: 645 From: Winnipeg, Manitoba, Canada Registered: Nov 2000 posted 01-09-2005 07:24 PM                        If only 70mm would come back...  |  IP: Logged Thomas King Expert Film Handler Posts: 119 From: Sheffield, Yorkshire, England Registered: Oct 2004 posted 01-09-2005 10:16 PM                        70mm never went away.

What great light! -Monte  |  IP: Logged
