Absolutely love your videos. The bit about the hilarious inefficiency of making saturated blue with halogen fixtures cracks me up every time. It never gets old. And your face scoffing at “white” LED is priceless.
I may have discovered a worse one! One of our painters brought in a very old UV light, which as far as I could tell, was just a halogen lamp with an incredibly thick glass filter in front of it, blocking out everything but the UV. It drew a lot of power and got stupidly hot and she was actually kind of amazed when I showed her the UV LED units you could now get for $20. She's teaching again this semester and I'm going to ask if she still has it and if so, can I take a closer look at it.
The painter in question let me have the lamp! It's a high intensity discharge lamp, not a tungsten, but it's still a very bright light with a very thick glass filter in front of it to filter out everything that's not UV. It gets _very_ warm.
Thanks for this! Great content! I am a professor of lighting design, and will absolutely be sharing this with my lighting students on Monday! Well done!
Great set of videos! I have watched them all and learned quite a bit. I have struggled with connecting low wattage lights (LED and conventional) to different modern dimmers without ghosting or light flicker. Even at a concert hall with modern electronic dimmers. Would it be possible to do a talk on the difference in modern dimmers (something around 1970 to now)?
I've got a question: what sort of equipment uses those Xenon lamps? I've tried looking for Xenon-powered stage lights to no avail, since I'd love one or a few for a collection. If they're built for general-purpose stage illumination, would you have a make & model, by chance? If I can't find any, I might just be forced to build one myself.
A lot of older moving lights use them. They were fairly common in followspots as well. I think the lamp in the video is out of one of our Martin MAC 600s. ETC also made a HID retrofit kit for Source 4s, but it doesn't seem to be available anymore.
@@Wyatt_Jamesxenon was used mostly in followspots and large projectors. Video location lighting may have used them as well. Most theatrical/moving head fixtures used some form of metal halide.
I managed to find a couple of very old Ushio xenon projection lamps since I left this comment, but I don't have any running gear. They were only used in a couple models of 16mm film projectors from the 70s, as far as I can tell. Should have went back and grabbed the one I saw there!

Ah, thank you! I've been able to find the keywords that I need from that Martin unit's model number.

18:04:... Read the Instructions... RTFM!
It is good to see you are using an old oscilloscope......
Be careful calling CFLs Soft Serve Cones. I might end up eating them in the middle of the night 🍦 💡
“Some have vacuum inside”….
That is a weird thing to say when you think about it.
