Stage Lighting Terms – A Guide to Lampie Slang

On Stage Lighting presents an essential guide to stage lighting jargon and UK lampie slang for anyone who needs to understand what these weirdos are talking about or needs to blag it as a member the LX department.

Every so often, lighting technicians have to talk to people in the real world (or lesser mortals like sound engineers). It soon becomes apparent that, as in every corner of life, there is a certain amount jargon. Lighting terms, slang and other gobbledygook that techies use when communicating with each other, to the exclusion of the outside world.
While a full glossary of stage lighting terms is outside of our scope today, here is the Blagger’s Guide to Lighting Jargon.

Dictionary

Some of the terms are lighting specific, others related to stage work in general and are based on the garbled utterings of UK based lighting techs.

Directional Terms

To an outsider, one of the most peculiar things about stage workers is their sense of direction. On stage, normal directional communication gets mangled. Any one who remembers acting in a school play will know that their drama teacher kept talking about “Stage Left” and “Stage Right. Drama teachers themselves often get this muddled up, so let’s be clear: Stage Left is your left hand side if you are standing on stage, looking out at the audience. This is the opposite of House Left (from the audiences point of view) or Camera Left (er, from the camera).

It doesn’t get any easier, though. Stagey people say Up when they mean backwards and In when they mean down. What’s that about?

Up and Down Stage are further and nearer to the audience respectively, relating to historically sloping stage floors. If something “runs up and down” it is not a fitness crazed techie (does anyone know any, BTW), it is something that has its long axis sitting at ninety degrees to the stage front. Up and down stage.

Conversely, it might “run on and off” (Onstage being nearer the centre, Offstage nearer the sides) with its long axis parallel to the stage front.

So having used up the terms Up and Down to mean something else, what are we going to do when we really mean up in the air or down toward the deck? Why, use Out (up / away) and In (down toward the stage floor) of course.

Let me be the first to admit publicly that my tiny brain uses these directional concepts by default, even when absolutely nowhere near a stage. Be warned of this before you try to move a sofa at home with your nearest and dearest techie.

Endless Numbers

Many of the different technical disciplines use numbers but the lighting department seem to barely use anything else. If you think that the world of business uses too much jargon, you should listen to two lampies outlining their plans for the next five minutes.

The trouble with deciphering the numbers is that they are used in a wide range of contexts and that context is only clear if you know what the numbers mean. Otherwise, they are just numbers. Let’s start by looking at what the numbers represent

Quantity and Capacity

Somewhere in the number jumble, there may terms that reference the quantity of items or the capacity of an item. Examples include five [insert another bit of jargon here] or a 6-way [bit of jargon] or a [bit of jargon] to 12 [other bits of jargon]. Also included in the capacity equation are references to power draw (1000 watt or 1k), current capacity or electrical rating (16 or 16 amp rating with appropriate connector type).
A final confusion factor is added to distinguish between equipment that is designed for use with 3 phase or 1 phase power. The term “3” refers to three phase power and thankfully the word “single” is inserted by thoughtful jargon spewers to reduce the shear quantity of integers in any one sentence.

Length

Lighting cables are not only denoted by their electrical rating and connector but also their usable length. The length of rigging kit is also something we might need to talk about. Rummage around in a lampie sentence and you will probably find a reference to the length of something, like 10 metres. 2 10s references two of something, ten meters in length.

So far, we have got the potential for a sentence to contain number that denote quantity, capacity, connector type, phase number. That just describes a piece of kit.

3 63 3s 2 3 63 singles refers to a piece of common electrical distribution kit: Three (of) [sixty three amp, three phase] plug to three (of) [sixty three amp, single phase] socket.

6 16 2 15, 3 10 metre 15 and 2 2 way 16s actually translates to : Six (of) [sixteen amp] plug to [15 amp] socket, three (of) ten metre fifteen amp cable and two (of) sixteen amp two way splitters.

Notice the use of the word “metre” to split up the length and the connector rating. Hey, anything else would just be confusing, right?

Manufacturer Numbers

Rather unhelpfully since the dawn of production lighting manufacture, the makers of stage lighting equipment have followed naming conventions for their various products that rely heavily on numbers. Lanterns produced by Strand Electric went from pattern numbers like 23, 264 and 243 on to ranges with real names that the subsets could only be described by their beam angles such as 16/30 or 11/26 ( 16 to 30 degrees and 11 to 26 degrees).

Modern lighting equipment manufacturers have continued on this unimaginative folly by mainly referencing fixture power such as 700, 1200 and 2000s. Fixtures made by different manufacturers get called the same thing, for instance, the Martin MAC700 profile and the Robe ColourSpot 700 both get called “seven hundreds”. And so it goes on.

4 700s on 3 at 200 translates to: Four (of) [some kind of 700] on bar three, starting at DMX address two hundred.

Reference Numbers

With lots of different parts to a lighting system, we need to be able to distinguish elements within it. In order to stop others from knowing what we are up to (other than skulking in Dimmer City) lampies have devised a cunning and impenetrable method of marking different control channels, dimmers, fixture addresses, intensity levels, gel references and circuit numbers. Yes, you’ve guessed it – more numbers.

The context that these numbers are used in is not so definable. They may be thrown into the middle of a sentence, their presence only discernible by the fact that the integer in question does not relate to either quantity, electrical capacity, length or manufacturer imposed number.

Putting it all together

By now you either knew all this already or are utterly confused. How do you work out which numbers relate to what? Here is some general guidance for cracking the number code:

Jumpers (not the woolly kind) that jump from one electrical connector into another are always referred to plug first. A 16 2 15 (often written 16 > 15 or 16 – 15) is a sixteen amp plug to a fifteen amp socket. Confusingly, in DMX cabling the number of pins takes over from the rating: a 5 to 3 is a 5 pin XLR plug to a 3 pin XLR socket.

Working out what a number it relates to is sometimes a question of knowing what it cannot relate to:

The number 101 is not one that relates to a fixture type, beam angle or common power capacity so it could either be a dimmer / control channel but chances are it relates to Lee 101 – Yellow, a vile yellow gel.

The numbers 16, 32 or 63 all relate to common UK power ratings and connectors but could also relate to anything else. You see how it’s all a question of context.

So, now you have started to get to grips with lampie grammar, let’s take a look at some other lighting terms and slang.

Lampie Rhyming Slang

The UK lighting business follows in the Cockney Rhyming Slang tradition with it’s own version of the language. In true Cockney fashion, the best proponents of this rhyming slang usually only refer to the first word of the term:

  • Billys = Billy Bunters = Punters = The General Public
  • Dianas = Diana Doors = When the Billys are let into the venue
  • Desperate = Desperate Dan = Lighting Plan

A particularly inventive use of rhyming slang is the phrase “Onions” which is a contraction of “Onion Bhajis” – it rhymes with Zarges, the popular brand of combination ladder.

Trade names

Every industry uses trade names in their own unique language, stage lighting is no exception. Here are a few of the most common:

Spanset – Technically known as a roundsling, the Spanset, Spanny or Spanz is an extremely strong webbing covered loop using for rigging and slinging.

Grelco – Common in the UK, the word Grelco refers to the specific type of plastic 15 amp 2-way splitter which this brand used to dominate. Younger lampies have been known to call them Snappers, after a more modern trade name. The 3-way version of the Grelco is inventively referred to as a Trelco or Trellies, in case you were wondering why Dave said he needed some trellis but does not seem interested in gardening.

Socapex – The popular brand of multipin connector used for dimmer and power circuits, “Soca” has become the lampie slang term for the entire cable as well. Other terms include Multi or Snake and different connectors are referred to by their dominant brand – Lectriflex, for example.

People

In the stage world, it seem like everyone has some form of derogatory term for those who dare to work in other departments. Some used by us “lampies” include “Noise Boys” and “Hum Scum” for the our arch enemies in the sound department and “Vidiot” for anyone involved with screens, tellies and cameras.

Electricians are unsurprisingly called Sparks or Sparkies while Chippies (carpenters) are also known by other phrases, depending on the level of abuse intended. “Wood Butchers” right through to “Hairy Ar*ed Nail Benders”. In the world of trades shows, Rug Tuggers are in charge of all flooring requirements throughout the hall.

For some reason, Riggers are often known by the most derogatory monikers but only from a distance. They are generally too scary to insult in person but the term “Nappy Wearing Sky Gods” cannot be heard above the noise of a cherry picker at 15 metres. “Nappy” refers a fall arrest harness and not to the results of a particularly vibrant curry from the night before. Watch out though, riggers have a special spy called the Groundman who lurks around on deck and reports insulting language to the roof via Motorola radios. They can also drop things on you.

Animals

In the stage lighting world, you don’t get too close real animals unless you happen to be on the electrics crew for a “Horse Of The Year” show (yes, I have). To feel closer to nature, lampies occasionally use animal based jargon including:

Spiders – a many legged, cabley thing that breaks circuits out of a mulitcore. If you are feeling more rock n roll, you can call them Fan In and Fan Outs instead.

Badgers Clamps – A  scaffold half coupler with an eyebolt for suspending barrel.

Pigtail – Any kind of short cable coming of something such as the power lead of a moving light or a flying lead from a breakout box.

Descriptive Lighting Terms

Sometimes, the best slang is based on an obvious likeness of something to something totally unrelated or a consequence of their presence. This is the case with:

Pickle – a pickle shaped hand held switch used to locally control electric chain hoists AKA the motors.
Ray Guns – Plastic 16a Ceeform 2-way splitter that looks like – well, a gun. “Sod it, Nev. Just gun ’em together, I can’t be bothered to run another 50 metre 16 to this one as well”.

Trees – Plastic 16a Ceeform 3-way splitter of tree like appearance.

Binoculars – More 16a Ceeform 3-ways that look…. Well, you’re getting the hang of it now.

Tripe – A bundle of cables, taped together for easier management that ends up looking like tripe. Another term is Loom.

String – Electrical, referring to cable including the largest of heavy mains supplies.

Shin Busters – Low mounted fixtures that trip everyone up, specifically the monitor engineer (if you get it right)

Acronyms

While the financial and business sector have the monopoly on outrageous acronyms, stage lighting jargon has it’s fair share. We won’t go into all of them, but here a selection:

  • AJ – Adjustable spanner, a UK term.
  • DBO – Dead Black Out. Everything dark.
  • TRS – Tough Rubber Sheath. A reference to the insulation on mains and dimmer cables . Used to denote a single channel of cable.
  • RCD – Residual Current Device. Safety switchgear that protects the user.
  • MCB – Miniature Circuit Breaker. Safety switchgear that protects the equipment.
  • FOH – Front Of House. Anywhere forward of the stage line or where the general public hang out. Also used when leaving – F*** Off Home.
  • FUCT– Acronym for various words including Failed Under Continuous Testing. Used to mark up faulty equipment

Unimpressed by Technology

In order for technical types to real feel that they are the masters of all the bells and whistles they survey, they resort to derogatory names for posh kit. This can be found in other departments such as the video where they habitually refer to the snazziest of 90” Plasma screens as Tellies.

In the lighting world, this practice is evident by terms such as Nodding Buckets or Wobblies for moving lights and Waggly Mirrors for scanners.

Contextual Terms

No highly complex language is complete without some terms that use the same word for multiple purposes, to the confusion of non-speakers. Here’s a few.

Dead – A height at which a flying piece rests. A busted something. Something that isn’t broken but is no longer required in this performance. “ Are these boxes dead?”

Strike – To dismantle the entire show. To remove something from the stage area. To fire up discharge light source.

Spike – To nail. To decide on a fixed position for something an/or mark that position. The use of white tape to denote a hazard such as tripod legs or Shin Busters.

How to pretend you’ve been doing this for ages

In order for the Lampie Blagger to convince those around them that they have been around since the dawn of nodding buckets, it’s a good idea to throw in slang from times past such as:

Cracker – The cracked oil machine referred to an early form of atmosphere generator. Today, they are usually called Hazers but using the word Cracker will really give you a history.

Black Light – Ultra Violet (UV) lighting effects are not quite so in fashion these days.

Floats – Floats refer to another out of fashion lighting technique, footlights. Originally floating wicks, footlights were used extensively for a part of theatre lighting history. Sound engineers still call low mounted microphones Float mics, don’t let them nick your terminology.

How to avoid getting rumbled

Here are some common Heffalump traps that will flag you up as a rookie instantly. Avoid.

Incorrect use of “Lamps” – Stage lighting technicians refer to lamps and never bulbs, although the word Bubble will give you an old fashioned kind of cred. Lamps never refers to the fixtures themselves, which are called lanterns or more specific terms.

SocapLex – This is a common faux pas and is like a sign that says “I hope to go there one day, but so far I have only bought the T shirt”.

So, that’s all for now. Now you should be able to order a cable, chit-chat in the local tongue and hurl abuse toward other residents of the stage area. What more could you possibly want?

    If someone knows you are new in the business, don’t get caught out by being told to go to Flints (a theatrical chandlers) to buy tartan paint, sky hooks (a common lampie/rigger joke) or a long wait (rather than a stage weight).

    If you do end up at Flints for these items they cost £10 each, even the guys in the shop have a sense of humor although your production manager or boss probably wont see the funny side after spending all of the budget on nothing!

    never used the rhyming slang myself, will bring it back! 🙂

    cheers Rob!

    To add to the theme, grelcos can sometimes get called OLBs – one lucky b****** – one male and two females…

    Sometimes Grelcos get called ‘Twofers’ or ‘Twofer blocks’ & we call ‘Trees’ ‘Crows feet’. They might be a ‘nappy’ to some, but to others they’re ‘safety trousers’

    In the Unimpressed category (though admittedly not technology) you forgot ‘The Turn’. They might be Stadium Rock Gods, adored & admired by millions, but to us they’re just ‘The Turn’

  5. cha0tic November 23, 2009 at 2:34 am #

    …and off topic, as it concerns the noise boys, but it’s one of my favourite bits of rhyming slang:
    Meat & twos.
    You know. Those speaker thingees they put on the down stage edge of the stage so the turn can hear themselves.
    Meat & Two Vege, wedge.

    Then back on topic whilst I’m still posting.
    It’s a Lighting desk, unless you’re a septic*, then it’s a Console.
    It’s a swivel (clamp) in the UK & for some reason that’s totally beyond me. A Cheeseborough on the other side of the Atlantic

    *More rhyming slang. Septic Tank, Yank’

    I have to admit, that part about Shin Busters is good 😉

    …I’m a Brit working in the USA. Can you recommend a website that has the US lighting slang and a US slant on the industry?

  9. klmklm February 12, 2010 at 10:08 pm #

    stuck way up here in aiberdeen, its nice to see its all universall!!

  10. Graham J McLusky February 19, 2010 at 11:12 pm #

    Great web site. Just found it. Will pass this on to everyone!

    The problem is that in the technical industries there are two many “TLA’s”… (Three Lettered Abbrevieations)

  11. Bridget April 3, 2010 at 1:53 am #

    I’m from the U.S. so this was really interesting! Great site! Here’s a few slang terms from the other side of the Atlantic:

    Over here, we call the sound guys “Hum Heads” and they call us “Squints” (all that squinting at instruments). But I think I like “Lampies” better!

    Grelco’s are called twofers. The 3-way version is usually called a threefer. Not very inventive, I know.

    ERS instruments are often called Lekos, even if they’re another brand.

    And my personal favorite bit of Squint Slang:

    The little bolt on C-Clamps, sometimes called the pan screw, which allows the shaft of the clamp (and therefore the instrument) to rotate 360 degrees is affectionately called “the f**k nut”. This is because it’s usually next to impossible to loosen the thing, especially on older clamps… and thus the vulgarities fly.

    Cheers!

    Hey cha0tic, I was told many (o so many) years ago that the scaffolding company that made them was named Cheseborough (second name I can’t remember). They were out of NYC I believe. They also use to be referred to as cheeseburgers, but haven’t heard that in years.
    And Bridget, my understanding of the naming of the afore mentioned “f*** nut” had to do with what the techie would scream when the c-wrench (spanner?) slipped and his hand slammed into steel. This would usually be followed by the wench being turned into a hammer and the offending little bolt being turned into shrapnel that would come flying out of the cats (FOH lighting positions).
    Finally, Rob I love your site. I can’t believe I’ve missed it all these years. Thanks for good info and great laughs.

  13. Mary June 3, 2011 at 8:42 pm #

    Can someone tell me the name for the term when you use spotlights zigzagging all around for the opening of a show, etc. What is it called?
    Thank you!!

  14. J from Toronto July 8, 2011 at 4:59 am #

    I think the term you’re looking for is “ballyhoo” for spotlights scanning.

    Up here a cheseborough is a cheeseburger — and that’s what you’ll hear from the peanut gallery until you’re done rigging whatever elicited the first mention.

    Twofers reign supreme here afaik, a threefer is clear — but I might not give you a grelco if you asked.

    “Blacks” either refers to drapery or to the clothing crew *should* be wearing – it does not refer to folks of African ancestry.

    I still mount instruments on floats — pretty much anything rigged with a yoke+clamp in the air would be on a float on the floor (more likely for FX lighting than footlighting btw). They may also be floor mounts, floor stands, or whatever descriptor comes to mind — but floats usually wins out.

  15. Uxbaz November 25, 2011 at 7:33 pm #

    The German for lampie is “pig thrower”. It starts as shine verfer (I don’t spell german sorry) which is light thrower. Shine to swine and there you go.

    Pig chucking and proud for a long time now

  16. Sebastian February 17, 2012 at 3:48 pm #

    Hi! Im quite new in lighting design and I’m looking for some information about “gloster” I understan it’s a type of pipe.

    Thank you very much.

  17. Martin May 27, 2012 at 10:38 pm #

    Another term for spotlight scanning (particularly when it’s the audience they’re scanning) is “Funky the scum”

  18. Rob Sayer May 28, 2012 at 4:00 pm #

    He he, Martin. Not heard that one before. Before the term Bally-Hoo was popularised in the age of moving lights, I’ve known at least one LD to call “Hollywood” to the spot ops for audience scanning.

  19. Dangly May 30, 2012 at 2:21 am #

    No-one has mentioned a Big Ben yet…

    Vidiots got promoted to picture tossers in our neck of the woods

  20. Rob Sayer May 30, 2012 at 8:43 am #

    I don’t really think of Big Ben as slang. What else would you call them? TV Spigot-cum-half-coupler?? 🙂
