    Strain relief

    You would be correct! The plastic strain relief might have gone brittle and could crumble when it's removed. If that happens, a bag of the strain reliefs is cheap. The tool is expensive, but there might be cheaper versions on Amazon. Or you could switch to a metal clamping-style.

    Dave Cunningham and the Magic of the Source 4--today at 2PM eastern

    I remember seeing a few of these on eBay at one point. They were going for a pretty penny! I can imagine the disappointment when manufactures started only producing dipped Par 38's. @STEVETERRY Thank you so much for providing us with this unique history and perspective. Fixture design and...

    Dave Cunningham and the Magic of the Source 4--today at 2PM eastern

    When was the ENX 360 watt lamp brought to market? Does it use similar technology? The Source Four's reflector always reminded me of a much larger and better thought-out version of an MR-style lamp.

    Strain relief

    It's either clamp-style or Heyco, I'd imagine. If clamp-style, it should be fairly obvious, with two screws you loosen to lessen its grip. The entire piece has a locknut on the back that unscrews for removal. If Heyco, I second @derekleffew 's suggestion in getting a set of the pliers. I have a...

    Altman 360Q Focus

    Your fixture's lamps are definitely set at different depths in the reflector. As Derek said, it could be a lamp seating issue, or it could be the center screw out of adjustment. If you adjust the center screw, remember to compensate with the three slotted screws to add (or relieve) tension as...

    Vintage Lighting Identity and date these fixtures?

    Looks like you have an Altman Shakespeare in the very back. It's still a good fixture for projecting gobos (including glass). It may need a new socket, but that's only a roughly $15 expense. The big dome fixtures are Scoops, probably 14". They make great worklights if you retrofit them to LED...

    Large HS Auditorium and Black Box Upgrade

    LED retrofit? I have never been 100% happy with retrofit dimming in a house lighting application. I would redirect the money for those dimmer racks toward proper DMX LED house lights.

    Vintage Lighting Kliegl Bros. Light Identification

    I would wire it to an external transformer and use a 12v lamp intended for landscape lighting. Failing that, even a 120v LED designed for enclosed fixtures. Life can still be hit or miss, but I've had more good luck than bad - especially if you use the best lamps you can get. I don't think I...

    Vintage Lighting Kliegl Bros. Light Identification

    Very cool. I'd think it could be rewired and upgraded to warm white LED for the sake of historical accuracy.

    Control/Dimming Analog control of 0-10v LEDs

    I love this idea. Our main sound engineer, who is also a network engineer, loves using Arduino/Raspberry Pi for stuff. He will take this project and help me run with it I'm sure.

    Control/Dimming Analog control of 0-10v LEDs

    I really appreciate everyone's input on this. This is as much of an academic exercise as it is a practical one. That being said, maybe I should just stick a Doug Fleenor DMX8DIM and a Northlight converter in there. It would cost some money, but we have a handful of old Altec 9444A amps to sell...

    Control/Dimming Analog control of 0-10v LEDs

    Thanks, Mac. That must have been Alan's line of thinking as well. Sounds like the best thing I can do is get a few drivers, a DC Amp multimeter (or make sure the one in my kit can suffice) and start designing a buffer circuit. I found a few ready-made op-amp boards online, mostly designed for...

    Control/Dimming Analog control of 0-10v LEDs

    Thanks, @tyler.martin for your response. I'll admit that I guess I had my (figurative) wires crossed, because your post raised more questions, but better for me to know this now. Here's what I have been told about my controls from an EDI Tech. - The output amps are LM358 and the sliders are...

    Control/Dimming Analog control of 0-10v LEDs

    It seems that 0-10v dimming is making a comeback (or actually never left) in the architectural market, and it has me thinking about a project. We are currently redoing our lobby areas and part of the longterm plan is adding lighting in areas where it wasn't originally. We have gotten around...

    Strand Century Dimmy

    All the more reason to differentiate :) No need to apologize. It just helps streamline troubleshooting and advice-giving when we're all on the same terminology. You've definitely come to the right place if you want to make this system work, or allow your existing dimmers to communicate with a...
