OK, if you have single-phase for incoming power; using 2 hots, a neutral = and a ground, here is the phasing in a 12-circuit CD80 pack: Dimmers 1-6 Line 1 Dimmers 7-12 Line 2 Disregard what I remembered in my first response.

I know that being in the realm of balanced = is important. I *think* the percentage is based on your transformer = rating.

Shall we say "less than good". For accurate colour rendering, you need an illuminant with a continuous spectral output. Discharge lamps are constitutionally incapable of this. Be the manufacturers as clever as they can, the fundamental spectral output of the discharge is always there. Sodium it the most noticed, at 589 and 589.6 nM. Mercury has strong output at blue. green, and UV. However clever you ae with the phosphors, these will still come through. I can still tell when discharge lamps are being used in a stage rig. You may say that it doesn't matter. It does to me.

My personal pet peeve is the way some people (mostly on other groups...the people here tend to be much better about this) leave their posts in 150-line paragraphs without breaking them up. I find as I've grown older (and more used to online communication) that properly-implemented block paragraphs really do kick ass as far as readability is concerned (all else being equal, of course). ------------------------------ Subject: RE: jefferson / adams Date: Thu, 28 Apr 2005 14:43:34 -0400 Message-ID: <6E497ADB607656479C24E6D7BF6B505A0196C7E9 [at] exchange.rmwc.edu> From: "Paul Schreiner" > I'm not sure if I'm prouder of John's views or Samuel Adams=20 > beer, since John is my great great great....grandfather.

My prefered shop-built expedient is to replace the string with cardboard, I always find the string twists around either the pencil or nail and I end up with not circular circles.

Message-ID: <2147483647.1114700287 [at] mharvey.d.umn.edu> Each semester I lecture an hour on color mixing in my beginning lighting course. I've developed the following web site with lots of links to some pretty neat online experiments in color vision. The lecture concludes with a simple color mixing demonstration using three 3" fresnels, a small lighting console and the projection screen at the front of the class. Somewhere I read L164, L132 and L124 mixed very closely to white and I've been using those colors ever since. I have the class of 18 students stand up and make a large circle around the perimeter of the room. Rotating clockwise, I have each student stand in front of the lights while I light them with various color combinations. My point is that combinations of additive and subtractive color mixing often produce unpredictable results and lighting designers do the whole production a favor by taking the time to look at costume swatches in a light lab demonstrating how colors will interact. If I can announce it ahead of time, I challenge the class to wear clothes as bright and colorful as they dare. (Hawaiian shirts welcome!) Wide varieties of patterns and colors of fabric produce some amazing effedcts, but even without advanced warning, some surprising effects pop up with the clothes the students happen to be wearing that day. ____________________________________ Mark Harvey Associate Professor, Theatrical Lighting and Sound Design University of Minnesota Duluth http://www.d.umn.edu/~mharvey From: "Storms, Randy" Hey all.

Do NOT store lights or costumes or soft-faced flats in non-climate controlled areas, such as sheds. Cycles of heat and humidity will corrode lamp contacts and cloud plastic lenses (Source 4) and cut serviceable life in half or worse. Costumes, of course, mold up quicker than my shower and some fabrics don't last long in too-dry conditions either. Soft-flats will go right to hell in high-humidity. Properly built platforms are OK. No storage is a common problem in NY. Rent-and-return is good option (and lets you play with more stuff over time and your shows won't all look like the same one) and so is the dumpster method.

You DO realize that a fluorescent lamp is a discharge lamp (using mercury instead of metal-halide)? The actual light output is (mostly) from the mix of phosphors on the inside of the tube. By varying the mix, you can get REALLY good CRI numbers, or "warm" light, or "grow" light, pretty much whatever you want. Many, if not most TV studios now use fluorescent lamps. The studios seem to be happy with them, they save a LOT of energy, and the talking heads aren't sweating from the heat of an incandescent. ---------- Jerry Durand Durand Interstellar, Inc.

I'm going to demonstrate my ignorance of US power systems, here. The Uk is very different, and some of the numbers I quote need divided by two. I just don't understand the words "single-phase (120/240) 3-wire plus ground", or rather, I don't believe it. Let me tell you how it works in the UK, and you will understand my incomprehension. Power comes in to the sub-station at 11KV, three-phase delta. It cones out at 220/380V three-phase star. All the equioment is powered on this basis. Any individual piece of equioment is powered between live and neutral, at 220V. With a heavy load, such as the stage lighting, the load is spread across all three phases, so that the neutral carries only the out-of-balance current. On a large site, with good planning, this is usually not large. Some motors need the big three-phase. Domestic installations are different. I have 100A of single-phase. My neughbour is probably on a different phase.

God forbid we bother to introduce any basic principles to University students, or expect them to learn anything beyond one way to approach one goal. Shadows?

Since common e-mail courtesy dictates that we not use html code in our messages, but instead use plain text, the underscore indicates a word of emphasis in e-mail where italics might go in a regular letter. The three dots are "ellipsis points". They are used to show deleted words. While they are technically supposed to have a space after the word and then a space in between each dot, in common usage (especially the relaxed formality of e-mail), they are found very often as I typed them.

I don't think that is the problem. Remember, there are two packs daisy chained at the end of the control cable. Only one pack was acting up. The signal is AMX, not DMX. The converter is at the light board. We are using the same control cable as we used before converting to a DMX board. Also, when I plugged the old AMX board in, the problem still existed. Right now, everything is conjecture, as I cannot presently get the pack to flicker. Is there anyone who has converted their old CD-80 sytems to DMX and kept the old AMX control boards? We could certainly stand to have a spare that was known to be good.

And do > the symptoms indicate an out of balance condition? There is no such thing as a "phase" with the feed we are using. The most common problem is for the neutral connection to become loose somewhere, which can cause all sorts of problems, such as excessive voltage in some devices and insufficient voltage in others. In worst case, this failure can cause equipment to burn out or catch on fire. This happened at my house about 5 years ago. Whenever something would start drawing power, such as the microwave or refrigerator, many of the lights in the house would momentarily change intensity. Suspecting a neutral problem, I checked the feeder cables at my distribution panel. The voltage on one side was 127 volts, on the other it was 118 volts. I verified all the connections were tight in the panel, but the problem remained. I called the power company and asked them to send someone out immediately. They sent a person the same day and he found that the neutral from the pole pig to my house was corroded and loose. Apparently the person who hooked it up did not use the proper aluminum/copper connector.
