I actually like the fact that they chose to use WAGO connectors on this as it makes it much faster to repair or service in the field. In any sort of theater equipment, fast serviceability is an important selling point. These connectors don't really add any measurable amount of resistance at the power levels we are talking and they tend to hold very secure with stranded or tinned wire. You can pull solid wire out of them but you really have to want it.

Those wago terminals are actually a lot better than they look at first. A lot faster then screw terminals, they don't damage the wire at all and the grip is extremely good. Those are called the wago 222, and there is a new version with a little bigger levers called wago 221. I gave away all my screw connectors after I found these.

The sulfur ones were excited by microwaves, and the bulb needed to be rotated by a motor. If I recall the tech died off for a few reasons, the primary one being the inventor not really wanting to license it out reasonably, and the fact that it had mechanical/rotary components. That and when you mention microwave technology, people who did not understand got scared of scary invisible (and not there) radiation of course... They were primarily installed in those air filled end lit tube systems in factories.

The sulphur at 2.45 GHz with magnetron (not solid-state RF amplifier) one were developed it seems by CeraVision UK and LG in Korea but each company failed the entry to market. I've never seen but heard lately that a new company made sulphur prototype has been now running solid-state at 433 MHz for high power and maybe small power with solid-state at 2.45 GHz. No idea if they've solved the troublesome issue to remove the mechanical-rotary of the sulphur bulb.

The rotational Plasma Lighting System is still on the marked and all the old problems are solved. The main problem was related to the power supply and the live Time and not to the moving parts. In 14 years of working with rotational Plasma lighting System I never had a failing motor!! It's just a question on part cost/quality relation. And thru new electronics the live time of a Magnetron is in the upper 50.000h The development of Plasma Lighting is still going on for special markets. And for the people that have a problem with rotating we have a static solution that is working on 1000Watt Bulb power. (-;

That reflector is a high quality electroformed nickel typically used with xenon short-arc lamps for its precision and resistance to UV radiation. The "AQ" refers to the reflective coating - vacuum deposited aluminium with protective quartz overcoat. This gives higher reflectivity in the visible range over the more standard electrodeposited rhodium but at the cost of lower durability.

There's a slight pwm-type noise just under 16kHz when you have the camera near the back of the operating light (~3:30 mark). Was that audible or was it the camera picking up the EMI? I wonder if those filter screens kill the EMI. Maybe you need to run with those in place to meet FCC requirements. If you get a chance in the next vid it would be funny to see if it will work as a an ISM jammer and/or see if it will pick up on an FM radio.

Great! In the 70cm ham band. Thanks Hive!

I used to own 2 television sets that used this technology, they were built by Panasonic under their "Lifi" range to highlight "Luxim Lifi" plasma discharge lamps. They offered a 5 year lamp warranty, and the units they built were unreliable for one reason or another (Never got more than one year out of the lamps). I believe the problem was with their RF feedback circuitry. The lamps were not a user serviceable part and it was like talking to a brick wall when dealing with the service department of my big box store who needed to have their hands held dealing with Panasonic since it was not a standard part and I had an extended warranty through the store, but that is another story. Interesting thing, I took one of the lamps apart years later, there is a "Radioactive Materials" sticker on the inside of the lifi 4000 case indicating Krypton-85, which I assume is in the capsule of the discharge pill, and I am guessing your unit is the same way. The light quality from those things is awesome though when they work. The unit I had was a module with everything needed including the lamp built into a very well machined aluminum case.

Now that I'm thinking about it perhaps those metal screens are for RF shielding... Just a thought... Another thought is that it's too bad those aren't DMX controllable...

+tesla500 16:52 That chip is likely not an RF generator. I'm pretty sure it is an LM25007MM (datasheet says the marking is SLYB, and it's in a VSSOP package). It's a buck voltage regulator. That's why you see the decent sized inductor next to it! :D My guess is that the RF generator might be that SOT23-5 device that you see near the center of the unit, in the area of the TO-89 package device. I also noticed the coil-whine type noise as well. Is that coming from the lamp or the power supply? Very annoying, at least for me, with my relatively sensitive ears. (my headphones are at a comfortable level too)

can you determine if the quartz lamp outputs any UV light and if so what it's spectrum would be? I'm wondering if this lamp setup might be a substitute for mercury or xenon arc lamps that are used for their UV output. mercury and xenon lamps used for microscopy have relatively short lifespans, sometimes only a few hundred hours. they also require a minimum runtime and a minimum cool down time lest they explode. I'm wondering if this lamp design has those same limitations.

Can you check the RF emissions on the one you didn't take apart, since you were talking about how it passed RFI certification?

Just tested it, pretty much the same in the assembled light.

Great vid! The RF part should be using ceramic substrate for lower loss and better heat conductivity. It would be fun to place the lamp in our meeting room and disable all those laser pointers working at the same band.

Regarding the non-FCC compliance, have you made sure the 433 MHz RF driver is earthed as well as the Luxim resonator, the RF cox and so ?

Awesome piece of tech, I wonder however why they didn't help adjust he color change by adjusting some forced air cooling

What is the problem with that much power being radiated? It will jam the 436mhz frequency for other devices that are using it?

the stuff around the lamp module is most likely thermal paste and graphite heat conducting tape. This is used to transfer the heat to the heatsink. So a tight fit is necessary :-)

I hope to see this lamp on youre set

The linked Luxim pdf details pretty specific burn orientation whereas their site FAQ says orientation doesn't matter - I wonder which is correct...

while it does make the construction feel a little garage factoryish those wago terminals are incredibly robust. they have video of a torture test where the entire wiring melts around the terminal but it still holds.

I have one of these lights, and the temperature is skewing a lot blue (I'm getting 11000k on the 5600k setting). Do you know if there is something I might be able to adjust on the unit to fix this by any chance?

This standard allows for over 2.5 million times the radiated power limit of normal consumer devices (FCC part 15 class B), in this case, 70dBuV/m @ 30m at this frequency, equivalent to 110dBuV/m @ 3m. The FCC part 15 class B standard allows 46dBuV/m at this distance and frequency. I was astonished that the FCC allows such an exemption.

I personally am hesitant about using them because of the stab-in connectors on duplex sockets, which are known to cause bad connections. I know, they're a totally different manufacturer and a different design, but I've never really had much confidence in these sorts of connections.

Can anyone explain the annotation at 19:25? He says it is 70dBuV/m at 30m which is the same as 100dBuV/m at 3m. But I thought the power followed the inverse square law, and so moving 10 times closer to the source would yield 100 times more power, which is only a 20 decibel increase instead of the 40 he shows. I appreciate if anyone can point out the flaw in my reasoning.

I was wondering what the advantages of an RF excited lamp are over a conventional arc lamp or metal halide.

HID and derivatives like this do have one major advantage over current LEDs: way smaller emitter size, which allows much better focusing. An LED putting out this much light would be about 5x the diameter so your beam would diverge 5x faster, or you'd need a 5x larger reflector to get the same divergence.

I'd say that depends, the ones you used in your project are especially bad in that regard, and you still need to do mosaic optics if you want hundreds of watts. There are things like CBT-140 from Luminus - emitting area is 14sqmm, but only around 4klm. AFAIR best efficiency for RF excited lamps is around 90lm/wRF, but continuous spectra is not the thing that LEDs are known for, but hey, you can already buy 180lm/W chips off the shelf, scratch that Samsung SPMWHT541ML5XAR0S6 - 212lm/W.

Hence Powercon being a thing! Good eyes spotting my mistake! I'd assumed it was a Powercon because, well it's supplying a decent current and its not an audio device...
