Author Topic: brand of lamphouse in Ideal Theatre pictures? Mike Croaro Master Film Handler Posts: 394 From: Millbrae, CA Registered: Apr 2005 posted 12-09-2005 02:56 PM                     Hi Folks: Just saw the pictures of the Ideal Theatre that Brad just posted. Nice theatre!. Unusual looking lamphouse. Does anyone know what brand it is. Vertical or horizontal lamp? Just Curious.

According to the manual, it is horizontal. -Aaron  |  IP: Logged Mike Croaro Master Film Handler Posts: 394 From: Millbrae, CA Registered: Apr 2005 posted 12-09-2005 05:53 PM                     Hi Aaron. Thanks for the information. It's so "boxy" I thought for sure that it was a vertical lamphouse.

Very interesting. One thing caught my attention. The manuel gives the following statistics regarding screen illumination: LP-1000 XBO-1000 Lumins: 9,200 for screen with 20-28 feet LP-1600 XBO-1600 Lumins: 14,100 for screen with 30-36 feet The unit uses a 14 inch dichroic coated glass reflecter. I find it hard to believe that the 1000 watt lamp could provide good light to a screen 28 X 12 (scope). I also have doubts about the 1600 watt providing good light to a screen 36 X 15 (scope). Any ideas? Does this unit provide such a big bang in light output? Just curious, Mike  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

The "box" was so small that the reflector was almost touching the rear and the ignitor was located near the lamphouse douser. It accepted HS bulbs and did project a much better light than the comparable ORC lamphouse of the period ( early 1980's ). Problems was the tricky spring loaded focus mechanism, IR heat damage to the ignitor and wiring problems if not properly ventilated...we sold many for export since it was small and easy to ship  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 12-10-2005 01:26 AM                        I had a couple of Pups once, but they looked more like the Xenex boxes. Different manufacturing dates?? They were great lamps. I was never in a position to compare them to Super Lume-X boxes, but they seemed to do the job very well.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-10-2005 11:31 AM                     The glass mirror used in those and the Xenex-1 is still a pretty darn good mirror to this day.

Definately more reliable than an ORC, but I'll take a small XeTron or Strong over it anyday.  |  IP: Logged
