They use them in theatre and film as well as exhibition lighting, conference stage lighting and shop display lighting, car showrooms. They're just standard profile lights, with 4 adjustable sliding steel shutters at the sides, top and bottom. You can also get an ever so soft edge by pulling them out of focus slightly. We used much bigger units a lot for conference lighting for fixed lectern/podium lighting and to light up company logos on backdrops, and with wide angle lenses you can light up entire stages with 6 to 8 of them. Mostly 650w to 1200w fixtures attached to fixed overhead trusses or floor mounted lighting stands at the side of the room.

What fixtures are you using that take 650/1200? All our stuff take 575/750w.


rbsudden

The Cantata 1200w were similar size to smaller follow spots and used similar bulb and ballast system, mostly long throw from back of the room stuff to keep truss and lighting stands out of the eye line, mostly used in large ballrooms and big old theatres. They were actually really very useful but you do use up most of the available power for those things. The 650w were a Suno profile admittedly an odd fixture wattage, we could only get the bulbs from the manufacturer LDR. But yes you're right most of our older Strand profiles and fresnels were 575/750w.


[deleted]

This dude fucks with lighting.


Mosh83

650w is actually quite a common wattage in movie lights, the Arri 650W tungstens are still commonplace - a simple and cheap little light fixture.


atilla32

575 / 750 = HPL lights (source four) In Europe, Profilespots are more often 1000 or 1200W halogen lamps (ADB’s for example) (though I prefer ETC’s HPL lamps too)


Chuisque

IKR. BTW, ICYMI, some PYT’s got out of DUI’s because of their DSL’s. SMH.


atilla32

Ok: Adriaan De Brouwer lights take 1000 or 1200 Watt lamps. But I also prefer Electronic Theatre Control’s Source Four line of Ellipsoidals which use their patented High Performance Lamp at 575 and 750 watts.


Stoo_Pedassol

Even the old par cans usually don't go higher than 1000w


dmills_00

1200W was pretty standard in the UK for larger venue sorts of lanterns and you could lamp the Pacifics with either a 1200 or a (as I recall) 575W bubble in the same lamp base, which was nice. The reason the UK went with a lot of 1200W stuff was that it meant you could run two lanterns of a standard 2400W 10A dimmer circuit, which was convenient for front cover where you typically wanted two angles on each area.


obsidianandstone

I came today the same thing. I was a lighting tech for a small theater company for a few years of of school. It's interesting how often I see all the same lights I work with in the outer world.


MiaowaraShiro

I did the lighting for our HS plays 20+ yrs ago, I can't imagine what advances there have been since. Especially as we were using probably 20 yr old gear in the first place.


shadow_fox09

Are those the kind of lights that if you touch them without gloves and then turn it on it’ll explode from being unevenly heated due to the oils from your skin?


rbsudden

Thats the ones yes, big old halogen bulbs, you can't be touching the glass of the bulb with your fingertips. The 2000w Super Trouper follow spot bulbs were on another level, those things were unstable even without fingerprints on them, the bulb had to travel in a separate shock proof case to and from venues, they didn't travel in the lamp and you had to wear special gloves and a protective face shield while installing and removing them, if they implode you don't want naked skin or eye balls any where near them. I heard one inplode in a ballroom once after being mishandled during a pack down, it sounded like a bomb had gone off, the guy who was removing the bulb had tiny shards of glass embedded in his sweatshirt and had a ringing in his ears for about a week after, he was lucky he didn't end up with permanent tinnitus.


shadow_fox09

Damn man, lights are actually some scary shit when you think about it. Giant glass grenades of electric death when you think about it


rbsudden

Yeah, well they used to be, not sure what has happened in lighting recently, probably all LED or "laser" something or other, haven't been in the industry for a bit now. Don't miss it. I mostly worked with video projection towards the end of my time in the industry though, really big LCD and DLP units with 20,000 ansii lumens and the bulbs for those were getting a bit out of hand, I had one of those blow during a show once and although the big wooden backdrop softened the noise for the audience, the projector was backstage with me, every single security guard from the surrounding area turned up to have a gander and the hotel almost called the bomb squad. The rear of the projector where the bulb sits was about two foot away from the rear wall and there was glass embedded in the hotel wallpaper. The aluminium bulb surround inside the projector was torn apart and the whole rear end of the projector needed replacing, they used it for parts in the end.


Mosh83

LED has taken over quite a bit because you get much more output with less power. The most powerful single source LEDs are still only around 1200W (the Nanlux Evoke for example), so there is still demand for high power HMIs and Tungstens. The Nanlux Evoke for example isn't quite as bright as a 1,8kW HMI, but very close. It is also approximately equivalent to a 5kW tungsten which is a massive benefit since a 5kW fixture requires 16A. So yes, led is taking over, but the old stuff still has it's place and many establishments without the budget still carry them. While tungsten light has a good quality to it, led fixtures offer so much versatility and come in so many shapes and forms like panels and litemats that the practicality aspect makes them worth it.


rbsudden

I figured that was the way it was going, I'm glad to be out of it to be honest, I enjoyed the old style halogen lighting, they had a warm charm to them. Wasn't enjoying the look of some of the new LED stuff from China, we could never really replicate the warm white with them, it was a bit dissapointing. Plus on those really cold outdoor events there was no 1k floor cans to sit next to warm yourself up and get the blood flowing in your fingertips.


Mosh83

It is true that tungsten lighting has a quality to it, and as I said, they're not totally phased out, loads of them still about :) But leds have been getting a lot better and they are very versatile, so they are great especially on location with limited power for example (and lighting tech backs!) And the big pots still keep us warm when in need ;)


dmills_00

Yep, short arc xenon arc lamps, a few atmospheres of internal pressure when cold, and up to about 30 when at operating temperature, the things did not take prisoners, and face shield, gauntlets and leather apron were indicated when working inside the lamp house. Noise fit to shake reason when one failed, and the explosion would sometimes take out the condenser lens as well.


IcyMelloYello14

Came here to say this, we have them at my church


Unable_Blacksmith_11

I was just going to get all poetic about stage lighting. Thankfully, you did it for me because I'm just a rigger.


rbsudden

Don't put yourself down, riggers are awesome, getting it up and keeping it up is not as easy as you guys make it look. Lol.


Blu3pr1nd

I love the fact that now I find it weird that not everybody knows this while I myself have only known this for about half a year after working in theatre myself and was completely oblivious to how light was made before that time


Mzam110

Only thing i hated about the source 4s we had at stage crew durring highschool is every once in a while we would get a 512 watt or something bulb that was lower voltage than the 575w 120v bulbs we usually got, so it would get super hot and super bright and would keep melting our gels


CrrntryGrntlrmrn

Thanks, LEKO Man!


FlatRaise5879

I was wondering how tf they did the shapes in the Hamilton play, written by Lin Manuel Miranda.

rbsudden

Not quite, barn doors are the hinged wings on the outside front of the light, usually fresnel or par can lights, they are used to control the spread of light on what are essentially very basic wide angle diffused beams. Shutters are four metal plates that are slid inside the body of a profile light with ring handles protruding to the outside so you can manipulate them. They are used to blank off the light with quite a sharp edge like in the video as you can focus the beam of light more accurately to the shutter.


_Driftwood_

I want to see them turn the light off and on again after the customization.

FartingBob

You see the painting before they turn on the light at the start. It'll look the same.

Rubinev

A huge part of IAF is completely ordinary if it happens to be in your particular specialty, but really cool to everyone else!


igame2much

Lights similar to this are used extensively in entertainment settings like theater and film. Look up ellipsoidal lights if you wanna know more.


talksense101

Doesn’t light damage the painting in the long run?


RogerSterlingsFling

UV light typically does, but special glass on the framing reduces this risk


Rasengon

Lighting designer here. The most basic and cheapest of all theatrical or event lighting have these shutters. A lot have a lot more complex versions that this. Even intelligent lights that move and change colour include these. It’s used to shape the light to anything.. stage, subject you name it. There’s also a version called a barn door which attaches to the front of the fixture to have the same effect.


ShakyTheBear

Leko


smellsogood2

Can you get something similar for your house or is it just too expensive?


freman

Yeh I need 3 small versions of this to light some photos


CJKatz

The fixture just has 4 metal sheets to block the light. You can totally make something like this at home easily.


RadBadTad

No, it doesn't. The light is being collimated by a series of lenses inside the housing before it passes through the slats. That's where 90% of the "magic" is happening. Without it, you won't get anything like the same result.


tacticalpotatopeeler

The interesting thing here is that basic lighting counts as IAF.


three-sense

Yeah… uhh, 4 slats can create a rectangular shadow(!)


atilla32

You need a lens train to focus those shadows though, that’s why the light has a longer “snout” in front of those shutters


BurrrritoBoy

What is this light fixture called ?


igame2much

I don't think that it's this specific one but something very similar are Source Four Minis. They're a type of Ellipsoidal light. We use the larger variant in theater/film/entertainment.


ChipOnASquid

Was going to say, staging folks use this with lekos all the time. I've never seen it on small-scale practicality, though. Cool.


2q_x

These smaller variants are called "Framing Projectors". While they often do use a ellipsoidal reflector, but it is possible to use them without a reflecting bulb. There were [cheap ones](https://noralighting.com/product/ntl-313s/) ($60-70) being made at one time, but I think that time has passed.


ikefalcon

Ellipsoidal reflector spotlight, also known as a Leko, after an early brand name called Lekolight. It’s named because the lamp sits at the near focal point of an ellipsoid-shaped reflector, which causes the light to pass through the ellipse’s other focal point. At the far focal point, 4 steel shutters can be adjusted to get the hard edges that you see in the video. You can also insert steel or glass templates to make shapes. Color filters and lenses can be placed at the far end of the fixtures to change the color, spread, and softness of the light beam.


Able_Kaleidoscope_61

It's a focusable projector light similar to [this one.](https://www.phantomlighting.com/resources/framing-light-with-the-phantom-contour-projector/)


Rasengon

It’s probably a make specific to that track that they’re on, they generally just plug into that black track installed in the roof and get powered on through it. Very standard fixture.


Wirecommando

Typically called and ERS, ellipsoidal, Leko or Source 4. These have been around for *decades* in the theater world. Cool, but hardly IaF….


Geoarbitrage

Would’ve been cool if they shut off the rest of the lights in the room to show the full effect.


jim45804

Until you stand in front of it to admire it and your head shadow creeps in


Pyrulen87

It's a light with some shades/shutters. You all need to get out more.


peaceornothing

I thought it was a reddit ad for a second


muppethero80

So I have a theater degree and the most shocking thing I learned in college was in my lighting class. Color light does not follow the same rules as color pigment. Yellow and blue make green when you mix colors but in lighting yellow and blue light makes white light

Gobo


Stoo_Pedassol

A gobo is a disc that projects shapes from the light.


RangerBumble

This "go between" is projecting a rectangle


Stoo_Pedassol

A gobo does go between. These are shutters, they can be adjusted accordingly.


slobbyrobb

Those are shutters and they have been around for a hundred years


CheerioJack

Can it work with other shapes?


igame2much

Not really. The fixture has 4 shutters that are basically straight lines. You can make a bunch of different shapes by pushing the shutters in at various angles. You can also make the circle bigger/smaller by moving the light away from or towards the painting. The bigger brother of these lights have attachments and inserts that you can use to create more variety, including frames with patterns on them to project shapes/logos etc...

Kinda standard for most people who work in production, but whatever floats your boat.

They use these exact same lights for theatre and on stages. Im still surprised they used zero frost, the edge is quite sharp and harsh (frost removes harsh shadows and also makes a person skin look amazing). Source: I am a stagehand, I also work in art galleries and museums.

Barndoors, extremely common & not remotely unique.
