Author Topic: Building your own lamphouse John Westlund Expert Film Handler Posts: 204 From: Burney, CA, USA Registered: Jun 2001 posted 10-20-2002 05:33 PM                     After reading about Sam Hunters lamphouse he has built I have decided that I am going to try and build one myself. This is the bulb I was looking at. Volts 100 Watts 1200 Color Temp 5600 Lumens 110000 Rated Life 750 http://www.topbulb.com/find/Product_Description.asp?intProductID=46853 Does this look like a good bulb for this type of project and where might I be able to find a reflector for this? Also, what would it take to power this? Thanks, John  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 10-20-2002 06:37 PM                     This appears to be an HMI metal halide lamp Typically the arc gap is to long for a Xenon style reflector to gather but to small for most stage lighting ones Also they are an AC arc so unless you use a square wave ballast you will have beat flicker Also by the time you build all of that you could buy a good used xenon system  |  IP: Logged Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 10-20-2002 07:45 PM                     Gordon may be right about cost. That Dichroic filter I bought cost about 110 bucks and with all the little extras I had to get I probably spent 300 bucks. After all this I found a nice Christie for 350 bucks. Anyway, I like to experiment and I learned a lot in the process. But hey if it works then I guess it will be worth it. The only reason I used the heat filter was due to how close the lamp was to the apeture and I was afraid it would get too hot so I erred on the side of caution. I decided to use the EKD bulb mainly because of the lumens, and filament type for the reasons Gordon mentioned. The color temp is a little below SMPTE standards but its higher than what the ELC's in Eikis are so I figured what the hell, better than nothing. I will admit that I could have gone simpler on my project but then that wouldn't be any fun.  |  IP: Logged Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 10-28-2002 08:54 AM                     If anybody needs a 7" round heat filter let me know. ------------------ Samual Hunter Sr. KC5ZSL  |  IP: Logged
