Electricity

 

 These are board notes from a lecture that two of our interns presented explaining how the electricity gets from the power company to the lamp. More info will be presented on this page in the future as this subject is often miss understood. Not to mention that it's also very important to lighting our shows.

Making New Brass Look Old: fume the brass hardware in a sealed jar containing 26° to 30° ammonium hydroxide is the tried and true method.  It is however hard to get hazardous material and has become harder to get.  It is usually available at a laboratory and chemical supply company, or commercial printer suppliers.  Use it only in a well ventilated area.  Wear eye protection, rubber gloves and a respirator with cartridges designed specifically for ammonia fumes.

Lamp life, color temperature

In response to a question to me off Pro-Sound Web's Lighting Forum. 

 "If I went with the identical lamp that's in this fixture, are you saying that it would be a more "brown appearing lamp"? You made that reference but am wondering if there is a lamp that is a more white appearing lamp as well. In the application that I will be using these lights, the distance to the stage is approximately 20 feet. I personally think that 575w is a bunch, although I am planning on hooking it up to a 600w per channel dim pack. Is it better to have the wattage there if needed, and just dim it when not? That sounds logical to me" ...

Brian's Steps to repairing a cable: Very Long...

Brian has been generous enough to contribute several pages of info to us and we are very thankful. I'll warn you though that the pages are filled with a lot of info. Take your time in reading what's here. As Brian admits, he types FAST!

Steps to repairing a cable:

(Preliminary Analyzing of the cable:)

1) Shake the ends of the cable at the cable.  (A plug with loose terminals will frequently rattle) This will help you find the end with the problem. If however one end is loose, they both will be so any repair to one side should be done to the other.  The female end of the cable is most frequently the end tensioned thus the one that will develop wires that break inside the jacket.  On the other hand due to people removing the plug by pulling on it' s jacket, that's the end that most frequently will have the jacket coming short of the plug.  Both due to stress can have problems with wires coming loose from their terminals due to pulling on them when the terminals are not tight enough and the strain relief does not provide enough clamping pressure on the wire.

Brian's list of Tech Books

Here is a list of books I have or have read at one time or another and am looking for once gain.  (The ones with no info behind their title.)  The list has stars denoting their sefulness.  One star is pretty much useless and a waste of money.  Two stars is for a book which is good for background or only one or two items in them useful, but on the whole still are not worth buying.  Three stars are for average books.  aSuch books are good to gain the basics of their subject only, but not specific enough to be of much use once they are read.
