PARnel Lenses

MRourke — Tue, 09 Apr 2013 00:44:37 GMT

I am looking for information about how the PARnel optics work. Does the 'focus' knob move the lamp back and forth like a traditional fresnel? How do the dual lenses work?

can the acc. slot for Iris or rotator also be used with a standard patterm holder?

Source Four LED washes

BarterElectrics — Mon, 25 Mar 2013 22:03:23 GMT

Anyone have experience with using the Source 4 LEDs as a front light system? I'm curious how well a wash works with the flat field of the optics.

In other words, an even front wash depends on an overlap of the field angles of the lights. With the LEDs having so little drop off, how successful can a front wash be?

Source Four Angle Sans Barrel

Jodaco — Thu, 31 Jan 2013 21:00:24 GMT

On several occasions, I have found it useful to hang Source Fours with no barrels in them. At a glance, this appears to produce a circle of light roughly equivalent to that of a Source Four with a 36 barrel, only without the easy ability to shutter, gel, or focus the edge. I don't know exactly, but I'd like to. Are there any specs on the beam and/or field angle of a Source Four devoid of a barrel?

Thanks anyone who knows!

Source 4 Beam Spread Question

Bill Kersh — Wed, 16 Jan 2013 23:34:34 GMT

I read the KnowledgeBase Article: Source Four Beam Spread Quick Sheet. The sheet states tha a 36 degree S4 will throw 50fc at 45'. Is this the same for a 575W and a 750W?.

Thanks

Use a 750W bulb in a 575W Fixture?

Bill Kersh — Wed, 16 Jan 2013 23:20:30 GMT

I am a volunteer at a community theater and we are on a pretty tight budget (go figure). Is it safe to use a 750W bulb in a 575W S4 Ellipsoidal fixture. We need more illumination but don't have the money for new fixtures and it would help if we could get more light out of the fixtures we have. At the same time, I don't want to do anything unsafe.

Bulbs for S4 750/115 Ellipsoidals

Bill Kersh — Wed, 16 Jan 2013 23:12:11 GMT

Anyone have a suggestion for what brand of bulb is the best for these lamps. A list of manufacturers would be appreciated. Thanks much

Source 4 Lens Test

bluehitchiker — Fri, 11 Jan 2013 08:31:36 GMT

Hi,

I recently started working in a theater that has been operating for quite a few years now. At some point, the barrels of all of the Source 4's were opened and cleaned but the lenses were mixed up. Just wondering if there is a way to test what degree a lens is, so they can be put back together correctly. Thanks for any help anyone can give.

URGENT!!! need help before my last show tomorrow - pleeeeaaaasee :-)

lmcniven — Sat, 22 Dec 2012 20:23:12 GMT

Hi all

I have one more christmas show to do and have just lost one of my etc revolution rwm/sm original. Even if no one can help me before tomorrow, I would love to know your thoughts and would love some advice as the following has happend twice now.

I have two revs, both powered by the same 32amp independant and dmx together - going through the one with no intensity first then to the one that is working fine.

i finished a matinee and was going to check my scrolls to see if they needed calibrating when i noticed i had lost a lamp.

I changed the lamp, but didnt get anything through, i changed to another new one and still nothing.

I reset the independants - as sometimes this works - several times but still no intensity.

I still have control over everything else pan tilt scroller etc, just no intensity so the dmx is fine.

The LEDs are showing the lantern is ok as they are, full and static green,amber and red.

I took off the shutter,gobo and scroller modules and everything appeared to be fine on them and inside the lantern, from what I could see.

Someone mentioned changing the two fuses that are in the base of the lantern i.e where the power and dmx are, but i can not find an obvious access for them.

This has happened to a different rev a year and a half ago, so either its a fault in lantern again and its just coincedence or i am being totally silly and have missed something obvious and possibly doing something wrong for it to happen again.

It is rigged 8m up and i am currently working on it off of a ladder, if needs be it will have to come down tomorrow before the show for me to investigate depending on what advice i get as it is timeconsuming getting it down etc.

When we got a replacement for the last time it happened, the person who delt with it has no record of what the problem was.

Can anyone help me or give me any advice at all?

Many thanks folks,

Have a good christmas :-)

Source Four HID PAR start-up time

Steve Martin — Mon, 17 Dec 2012 23:19:39 GMT

I am considering a purchase of Source Four HID PAR's to use as on-stage work light. They would be on a switched circuit. I have three questions:

What is the cold start-up time for the HID PAR .
What is the hot re-strike time for the HID PAR.
Is it likely the HID PAR can cause the stage curtains to fade. The reason for this question is that we have had flourescent fixtures as work light in a couple of rooms on our campus and this seemed to have caused the curtains to fade. It may have been unrelated but seemed to be the culprit.

Also, do you have any better suggestions as to what kind of fixture I might use for this purpose.

Thanks,

Steve Martin

Hazy Gobo Issue

rtmacd — Fri, 14 Dec 2012 19:33:32 GMT

I have several 36 degree fixtures all with the same gobo. Most of them look great but I have a few that are very hazy when in focus. It looks as though there is a bunch of light spill coming from somewhere in the fixture. Can anyone tell me what is wrong and what I may need to fix or replace?

I've attached a photo of the problem fixture.

Thanks,

Ryan

Candela on S4 PARs

jhonsaker — Wed, 28 Nov 2012 16:27:59 GMT

Can anyone tell me why it is that the Candela for a MFL and VNSP has a lower fluctuation in the center of the fixture?

Just noticed it for the first time during a training session today and am quite interested in finding out why. Is it a reflector/lens issue?

Replacing House lights

Ricky Newkirk — Tue, 27 Nov 2012 18:55:31 GMT

I am in the process of trying to find a good replacement for some of my house lights. Right now they are 12 regular PAR 64 par cans, a row of 5, a row of 4 then a row of 3 . My problems are many because there is no ceiling over my lower orchestra seating, everything is hung from the roof (aprox. 55') except for 4 that are hung from my 2nd catwalk. The only way to change the lamps is to rent an $800 per day pew lift. Needless to say I need something more efficient then 500w par cans. LEDs won't work because we can't afford to run data lines to each lamp, we would have to scaffold the whole area. (that is how everything was installed) and it is a High School building so my budget is not huge! I am looking at replacing with SF pars and increasing wattage from 500 to 750. I also want to try an maintain the asethic look of the hall when this is done. Does anyone have a better suggestion or idea? Our building is only 9 years old and I would love to get my hands on the electrical engineer or architect that left this mess for me! Any help will be greatly appreciated!

Source 4 VS. Source 4JR

cbernier01 — Tue, 16 Oct 2012 20:35:52 GMT

Good Afternoon.

I am looking to purchase new lighting equipment for the theater I work in. We're in a 50' x 50' black box theater with a 20' grid. (5x5 spacing)

I, like most folks, am a big fan of the Source Four. However, in dealing with college budgets, I can get more units if I use S4 Jr's. Does anyone have any stories, good or bad, to help me justify purchasing one over the other? Or perhaps I need to look at some combination of both units.

Please let me know. I am looking for any advice that folks might have. Thank you very much!

Ballast - ETC Source 4 HID PAR

James Araki — Mon, 01 Oct 2012 21:57:22 GMT

Is there anything special about the ballast for a ETC source Four HID PAR

It looks as though it cost as much as a brand new fixture.

Temperature of Source 4 pars w/ 575w lamp

pemobley — Thu, 13 Sep 2012 20:49:06 GMT

Hi,

How hot do Source 4 pars get, using 575w lamp? What is the max temperature they could reach indoors, used for no more than 2 hours continuous on?

thanks,

Need help replacing reflector

johnlott — Wed, 16 Sep 2009 21:07:16 GMT

I have a reflector on a source 4 elipsoidal with a big ole crack in it and need to change it out. I however have not found any documentation to help with the process. I would greatly appreciate any help here.

Reflector of the Revolution

Pedro Alves — Wed, 20 Jun 2012 17:32:02 GMT

Hi all.

We've got only 10 Revolution since 2006 and all of them always give us a headache. But now that we've got some time free we open all of them and saw that on 10 Revolutions 9 have a broken reflector. Some cracked others broken. Is it normal that this reflector crack?? We use sometimes for longs periods the Revolutions but we've got others fixtures olders than this Revolutions and they never crack the reflector, only the rest of the projector.

What is the reference of the Reflector for we to order to our dealer?? We've look on the manual and online and we can't see that reference.

Best regards

S4 Lamp cosine, peak, flat

Lukas — Wed, 27 Jun 2012 12:40:34 GMT

i found some sheets about Gel life in S4s.
I do understand the focus options of the lens tube but what about the lamp.
There are different options like cosine, peak and flat.

I've read the "S4 peak and cosine fields" pdf, but i still need to understand how to make the different in adjusting the lamp

Any Help?

Thanks a lot

Lukas

Adjusting S4 Zoom

Lukas — Thu, 03 May 2012 10:57:44 GMT

we're adjusting our S4 Zooms, well at least we try.
Some are pretty fine, but on soom S4s it seems to be rather impossible.
In the middle of the spot, it is most time OK, but at the edge of the spot we got problems.
Sometimes there is a "shadow-ring", about 10 centimeters from the edge.
At other S4 we got "eyelashes" at the edge.

Any Idea how to get rid of them?!

Thanks

Lukas

New Fresnel

nfarwell — Tue, 13 Sep 2011 20:38:37 GMT

I got them today, unpacked and started poking at them:

Likes:

The lamp replacement method is awesome.

The locking focus adjustment is great.

It's a Source Four! OMGBBQ!!11!

They are light and seem sturdy.

Dislikes:

I'm going to need a spare bag of the spring retaining clips immediately. Just opening them and closing them once has bent 3 of the clips, requiring rather a lot of fidgeting to get the gel frame door shut. Is this really the best method?

The gel frame door is no longer a one-handed operation, making us ladder-dwellers sad. Sadface.

I'll connector them up today and turn them on. More reports later!

Anyone for a 19 Degree Source Four Jr Fixture???

Jon Frost — Sun, 20 Feb 2011 02:56:52 GMT

Providing lighting for small theatre and convention events, I use mostly Source Four Junior units and Par/Parnels. Seems only logical to have a 19 degree version of the Source Four Jr. Next to a 19 degree Jr., I'd use the 15-30 degree zoom as well. I lamp all my fixtures with 575w long life HPL bulbs.

If anyone else is interested in ETC manufacturing either of these fixtures, drop Product Development a note or phone call.

Thanks,

Jon Frost

Fan issue on Revolution.

Jakob Eriksson — Thu, 29 Mar 2012 08:57:54 GMT

I´m responsibility for stage light i our conserthouse which consists of three larger stages. On two of them we have Revolution. From day one it has been to much nocie from the fans so our symphony orchestra (I can tell they make alot of noice themsellfs...) wount use them. It´s not the scrollerfan (I know you can control it) that make the noice I think it´s the base fan that´s the worst. We have got fixture from diffrent years and they behave the same way. This suppose to be a silent fixture and consider to all i spoke to no one have had this problem. I can tell by my self that our fixture make more sound then fixture I´we meet through touring. How do I solve it? Software, physical modification or another fixture?

S4 70 degree lens and changing to 50,36 or 26 degree

Ric — Wed, 21 Mar 2012 00:49:14 GMT

Hi Guys,
We originally purchased 90 degree Source 4 units but ended up getting 70 degree lenses instead as 90 was far too wide for our use. ( long story...)

Can we just buy additional 50, 36 or 26 degree lenses for these units and have them fit fine?

The download tech info for the Source 4 s and the price differences give the impression that the 70/90 degree units are somewhat different to the 19/26/36/50 units.
