  • S4 H.I.D. recall

    I understand there is an ETC recall related to failing H.I.D. Source fours. Anyone had sucess in claiming a recall? How long is a ballast expected to last anyway? It seems crazy that you have to buy the entire "burner assembly" which is almost as expensive as a new instrument. Anyone else had...

  • Source 4 Maintenance Schedule.

    So I work at an outdoor theater in southern california. I have come to the end of what I can deal with fixing our old fixtures and have gotten preliminary approval to purchase about 18 S4 next before the next summer season. With additional purchases being made in the future. My question is this... Since...

  • Re: A question on Source4 photometrics

    Hello georgeg, The “standard formula for computing lumens” you have must have an assumption of what the beam profile is as this equation does not seem to take that into account. Maybe that assumption doesn’t fit the Source 4 beam profile. Where did you get this formula from? Take a...

  • Re: A question on Source4 photometrics

    For some reason this question has fascinated me so I got one of our Optical Design Engineers involved and this is what he has to say about the matter: Okay, here is what is going on. The equation used by the student is correct for a source that radiates uniformly in all directions, such as a bare HPL...

  • Re: Need help replacing reflector

    I followed the instructions in the S4_Assembly_Guide pdf on the etc web site, but with a twist. Instead of the 'drop & pop' idea mentioned, I used a drill press & 8 saws-all blades. >I took a piece of high density foam & put it on the bed of the drill press, & cut a chunk the...

  • Sticky lens train guides

    I have 100+ new S4 ERS's with a mixture of 19's, 26's, & 36's. I am experiencing problems moving the lens trains during focus. Most of the lens trains are in there original bodies, but some have been swapped around with our 80+ existing bodies. This issue has been really slowing down...

  • XWFL Missing Cd MF Information

    So I am a student and I am glad I did not procrastinate on the current project I am working on! So I am figuring out Foot Candles of all the source four series which create a field diameter of around 10ft. I have successfully done this for all fixtures lamped at 750, 575/115, 575/115X, except for the...

  • Source Four HID PAR start-up time

    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...

  • Source 4 Lens Test

    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...

  • Source Four LED washes

    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...
