49 assorted DHA gobos for sale. Have been in a lantern briefly, very light discolouration visible on the metal, but absolutely flat with no warping. Mix of A-size and B-size. Message me for a list of designs/quantities. £5 each.

100 assorted DHA gobos for sale. Brand new and unused, but not in original packets. 1 A-size, 99 B-size. Message me for a list of designs/quantities. £5 each.

I've had some cheap but very cheerful ones from CPC before now. Not sure about VGA connectivity, though, the ones I've used have all been composite video. Might be worth a look.

The Glasson stuff is really good - have programmed a load of it on a couple of pantos. Theatr Clwyd in Mold have quite a lot which only gets used around Christmas - they might be up for hiring it to you if you need it at a time when they don't. Drop me a PM and I'll hook you up.

Lights4Fun and Festive Lights are both great suppliers for this sort of thing.

1 is a CCT Freedom. 2 I think might be a CCT Minuette. 3 perhaps something Selecon, but didn't the later-generation Strand Lekos have shutter handles like that? 4 looks like a Strand Prelude. 5 is a Strand Cantata.

Some very bad journalism, and bad writing, in that Daily Fail article. Early on, it clearly states that a doctor had to staple Twitter back together last night! Many of the comments at the end are a pretty good indicator of what's wrong with people's general mind-set in situations like this these days, too - so much talk of blame and pointing fingers, and I only had to read a few comments before finding the first one suggesting that the audience should start looking for someone to sue. Very sad.

Impossible to know for certain - too many conflicting reports. Some say ceiling collapsed ; some say large numbers of people leaning on balcony rail caused front couple of feet of balcony to fall. Reports less than half an hour ago were saying that 30 were injured - now the number has gone up to 80, including a few serious. No point speculating on anything, as the exact details won't be fully known for a good while yet. All that can be said at this stage is that if any BR members are on the venue or show staff at the Apollo, or were in the audience tonight, I hope you're OK.

Thanks for the offer, but thanks to Bill Richards at Strand I now have the diagrams I need.

Anyone got a service manual or a circuit diagram for a Strand Act6+ dimmer pack? The 'updated' model from the late 90's - the one with the fuseholders along the bottom of the rack, not down the left-hand side. Ta.

Hello! This is a pleasant little refuge from the hustle and bustle of the BR, isn't it? :) For what it's worth, once I'd ticked the relevant box in my account on the ALD website, I had to log out of the BR and log back in again before the ALD forum became visible. Might be worth mentioning this to anyone who's already a BR member and is trying unsuccessfully to access the ALD bit.

Not sure whether this is the root of your particular problem, but there was an issue with the PSUs in a lot of MAC550s - one of ours died completely, and when we kicked up a fuss with Martin (they weren't very old at the time) they admitted that there was a problem with a big batch of PSUs and swapped all of ours out FOC. Might be worth a phone call, in case that's what's causing your issues.

Showing the iron is normally a condition of the theatre's licence. If a particular set design or stage layout makes it inconvenient to show the iron, then it is possible to apply for an iron waiver on a show by show basis - but you'd need a very good reason to convince the fire officer that you can't show the iron before the show or during the interval, and you still need to make arrangements for it to be able to come in in case of an emergency anyway. Any set that we have for one of our shows which will impede the progress of the iron to the stage floor usually gets around it in one of two ways - an iron buffer is installed which provides a continuous fire break to the bits that the iron doesn't cover ; or bits of false floor can be made in such a way that they can be lifted/pivoted/slid/removed to allow the iron to get all the way in.

Yes. Next question ...

Sadly, yes. Strand seem to have (or had, at any rate) a habit of using obscure and hard-to-source components in their equipment - sometimes it seems that, if there was ever a choice at the R&D stage between a component that was readily-available in the UK and easy to source if spares are required at a later date, or one that's different enough to make it incompatible with anything else and consequently has to be shipped in from another country, their engineers went for the second option. Barmy.

An Act6 being "non-DMX" doesn't define which version it is - it could be the same as the variation that another user might think of as being the DMX version, but without the DMX input card. If, on the other hand, we're talking about the very early Act6 racks (black rather than grey, with only one socket per channel), then I honestly can't remember what sort of fuseholder they have in them - we only have a small number of them, and it's been a long, long time since I've worked inside one.

Not quite true, Boatman. Perhaps some versions of Act6 use panel-mount fuse holders - IIRC (and I'm sure I do!) the ones we have use PCB-mounting ones, which we had to get direct from Schurter.

We recently needed a few spare fuse carriers for Act 6 racks. After much searching, we discovered that the only place from which they're available is direct from the manufacturer (Schurter) in Germany, who sold us some at a reasonable cost. If I think on when I'm back at work tomorrow, I'll dig out the contact details for you.

That's all well and good, but don't forget what Pete originally posted ... Suggestions of multiple fixtures costing £100 each, or Golden Scans, Robocolours, etc. are hardly low-cost ...

'Nix has hit the nail on the head. Multiple sources are more effective than one single powerful source. (Although the brighter the sources are, the better it looks!) I've found that one of the most effective sources of light for a m/ball is a very narrow angle profile, not too far away from the ball (but far enough that you can get a reasonable edge), irised or shuttered in to the ball. Three or four of these work just fine.

This FAQ is now replicated, extended and superseded by the one on the Blue Room Wiki, here. The Blue Room Lighting FAQ What do the numbers on Par 64 lamps mean? Par 64s use various different type of lamps, which have a fixed beam angle and can't be varied in the way that profiles or fresnels can. Par lamps give out an oval beam, hence why you will usually need to rotate the lamp inside the parcan to achieve the focus you are after. The most common lamps (and their closest 120v equivalents in brackets) are as follows : CP60 (FFN) - clear lens, beam angle of 9x12º - VNSP (Very Narrow Spot) CP61 (FFP) - frosted lens, beam angle of 10x14º - NSP (Narrow Spot) CP62 (FFR) - lenticular (stepped) lens (looks like a car headlamp), beam angle of 11x24º - MFL (Medium Flood) The following lamps are also available, but encountered less frequently : EXG (240v) - beam angle of 57x21º CP95 - grided lens, beam angle of 70x70º - WFL (Wide Flood) FFS (120v lamp) - lenticular lens, beam angle of 24x48º Par 64 lamps also come in 500w flavours, with slightly different beam angles. These are number CP86 (VNSP), 87 (NSP) and 88 (MFL). [N.B. - the number in ParXX (e.g. Par64) is the diameter of the lamp in 1/8ths of an inch] I need to make up some single-phase extensions.

It's impossible to give a full list of colour sizes for every available lantern in a limited resource like this. However, here are a few of the more commonly-encountered sizes (all in millimetres) : Strand Prelude - 150 x 150 Cantata, Harmony - 185 x 185 Alto - 245 x 245 Coda500, Nocturne - 240 x 214 Coda1000 - 285 x 240 Iris - 395 x 305 SL 19, 26, 36, 50 and zooms - 160 x 160 SL 10 - 305 x 305 SL 5 - 405 x 405 Patt.23 - 100 x 100 Patt.123, Patt.23N, T-Spot - 165 x 165 Patt.223, Patt.743 - 215 x 215 Patt.243 - 298 x 298 CCT Minuette F, PC, profile - 125 x 125 Minuette flood - 220 x 230 Starlette 1k fresnel - 185 x 185 Sil 30, Sil 40, Freedom - 185 x 185 Sil 15, Sil 25 - 245 x 245 Sil 10 - 205 x 205 ETC Source4 19, 26, 36, 50 - 160 x 160 Source4 10 - 305 x 305 Source4 5 - 356 x 356 Source4 Par, Parnel and Zoom - 190 x 190 Source4 Junior Zoom - 155 x 155 PAR64 - 250 x 250 I've found an old Strand lantern and I'd like some more information on it Try visiting the Strand Archive at http://www.strandarchive.co.uk. On the site is a huge database of old and new equipment alike, and should be able to provide you with detailed information about your lantern. You can also get info on Strand's line of control equipment past and present, too. What software is available for creating lighting rig plans? Good, but expensive, software includes: wysiwyg AutoCAD Vectorworks Cheaper software includes: Turbocad LX Designer Free, but less good, software includes: Sweetlight (requires specific hardware) Google Sketchup There are plenty of other 2D CAD packages out there to explore, all of which will do the job one way or another. I'd like to be able to work on the programming for my show before I go to the venue. How can I do this? By visiting the website of your manufacturers desk you can download a piece of software called the offline editor. This allows you to work or edit your show on your PC as if it was the lighting desk. The manufacturers that offer offline software are: Strand (for the GSX, 300 and 500 series) ETC (for Expression 3, Insight, Express and Congo Consoles) Zero 88 (for the Frog, Fat Frog, Leap Frog, Bull Frog & Mambo Frog) Avolites (for the Pearl & Diamond 4) Flying Pig (for the Wholehog 2) MA Lighting (for the GrandMA) Jands (for the Vista) Clicking the links will take you to the relevant websites. I've downloaded and installed the Strand Offline Editor, but when it starts I get an error message asking for "TNT.dll". I'm using Windows XP. Whats going wrong? Unfortunately, the Strand Offline Editor doesn't work in Windows XP, not even in a DOS box. Theres a few ways round this, but they're all a bit cumbersome. You can find a discussion of this here. The most elegant solution we've found so far is MarcTs' RAMdisk version of the OLE, more details here. What software can I run a show from and what about USB-DMX Dongles? There are lots of PC based lighting control products, the good, the bad and the ugly. Most are bad or ugly, good to look at are... PCStage LightFactory Horizon Chamsys MagicQ BlueLite Dongles comes in all shapes and sizes, from built and tested commercial offerings to 'open source' projects...

Socapex : 1 = Circuit 1 Live 2 = Circuit 1 Neutral 3 = Circuit 2 Live 4 = Circuit 2 Neutral 5 = Circuit 3 Live 6 = Circuit 3 Neutral 7 = Circuit 4 Live 8 = Circuit 4 Neutral 9 = Circuit 5 Live 10 = Circuit 5 Neutral 11 = Circuit 6 Live 12 = Circuit 6 Neutral 13 to 18 = Earth Lectriflex (Harting) : 1 = Circuit 1 Live 2 = Circuit 2 Live 3 = Circuit 3 Live 4 = Circuit 4 Live 5 = Circuit 5 Live 6 = Circuit 6 Live 7, 8 = Earth 9 = Circuit 1 Neutral 10 = Circuit 2 Neutral 11 = Circuit 3 Neutral 12 = Circuit 4 Neutral 13 = Circuit 5 Neutral 14 = Circuit 6 Neutral 15, 16 = Earth What's the pin-out of a DMX cable? Pin 1 = Ground Pin 2 = Signal -ve Pin 3 = Signal +ve (These pin numbers are true for both 5-pin and 3-pin connectors, although strictly speaking 3-pin connectors should not be used as they don't comply with the official DMX512 standard.) Some older Martin fixtures (such as the Roboscan Pro 518 and Robocolour 400) use the older Martin Protocol which switches Pin 2 and 3 so the pinout is Pin 1 = Ground Pin 2 = Signal +ve Pin 3 = Signal -ve If using these fixtures along side fixtures with standard pinouts, you'll need to create an short adapter (M-F, for use after the last standard fixture, and F-M for use before the next standard fixture) using the wiring shown below 1-1 2-3 3-2 Do I need to terminate my DMX line? Yes, all runs of DMX data should be terminated - this will prevent 'reflections' of stray data coming back up the line and corrupting the signal. To make a simple terminator, all you need is a 5-pin XLR plug and a 120-ohm 1/2-watt resistor. Simply solder the resistor across pins 2 and 3 of the XLR (sleeving the legs of the resistor is a good idea to prevent shorting). What's the pin-out of a 4-pin scroller cable? Pin 1 = Ground Pin 2 = Signal -ve Pin 3 = Signal +ve Pin 4 = +24v or +48v DC Why do I sometimes see two current ratings given for fixtures with discharge lamps? During the fraction of a second that a discharge lamp is striking, it pulls more current than it draws while running (perhaps several times as much). This can cause problems if you're trying to run several moving lights from a single power feed - the rating of the feed might be sufficient for the operating current drawn by all the units, but if all the lamps strike at once the current peak that's drawn momentarily might be several times what the supply's rated for - at best this can cause a voltage drop sufficient to prevent the lamps from striking, and at worst it can trip the circuit protection device. Where can I buy second-hand lighting equipment? AC Lighting's second hand and stock clearance list. Stage Electrics. VLPS. 10 out of 10 PSLX Enlightenment What's this I've been hearing about a change in the colours of 3-phase cables? The IEE published an ammendment to their wiring regulations, specifying new cable core colours for single-phase and 3-phase installations. The old colours (red/yellow/blue for phases, black for neutral) have not been used since the end of March 2006. The new 'harmonised' colours (brown/black/grey for phases, blue for neutral) have been used since then, though it is not necessary to replace any existing installation. For further information, please refer to the IEE website. How can I use two lighting desks to run one rig, for example one to control generics and one to run moving lights? There are two ways this can be done. 1) Use two seperate 'universes', i.e. the generic desk runs to your dimmers and moving light desk uses a seperate DMX tie line or cable to go the first moving light and then daisy chain out. This keeps everything seperate, and is less likely to cause problems. 2) Use a DMX merger, such as the ELC DMX Merger 2 in 1 (http://www.leprecon.com/elc/mini_dmx_merger.htm) or the Compulite DMX Merger (http://stagetec.co.uk/php/index.php?sectio...;contentid=1305) which enables you to use both desks in 'tandem' and combine their DMX outputs into one stream. Due to the serial multiplexed nature of a DMX signal, using a simple passive 'Y-lead' splitter to link two consoles into one DMX line will not work! How Do I Light A (Rock) Concert?
