- An experiment was done to see how an overballasted e.g. 1 kW or 0.5 kW ballast was inserted in a HPS or MH bulb. and see what happens.
at 04:18 a hole has melted in the arc tube of lamp Nr 3.
It was carried out in a controlled environment. - Věda a technologie
Excellent video! Love the distressed HPS lamps, the capsuled ruptured and Sodium deposited on the glass outer envelope. Well done for 15 years on Utube!
Thanks Ian.
Congratulations on 15 years of cool stuff! Keep it coming! 👍
👍
You (and Aussie, RIP) got me more into my (then small) electronics hobby when I was a kid probably over 10 years ago now.
Haven't watched every video since then of course, though I watch some time to time.
Super glad to see you still uploading after 15 years!
Thanks for your kind comment.
Cool video. Interesting seeing how these lamps start with a bluish / pink glow due to the "Penning mixture" (neon and argon). Then as the sodium vaporizes it adopts that classic and beautiful orange glow.
Congrats on the 15 years Ray, I've been following your channel for quite some years. Yours, among some other channels, inspired me to build my own flyback & MOT setups years ago. Keep 'em coming! 👍
Holy crap!
Happy 15, dude!
Congrats on 15 years!
I havent been around HID lamps too much in the past 8 or so years, before that it was almost daily..
Best thing about HPS and Pulse start MH is they sometimes fail and will completely mirror the inside of the lamp as yours were...
Have used mirrored "ED17" and "ED28" shape bulbs as christmas tree decorations as they look similar to old school christmas light bulbs only way bigger and cool looking.
I've only had probe start ones just not start anymore or start cycling. Nothing as fun as the quartz tube going snap and silvering the outer envelope.
I tried putting an expired probe start bulb in the microwave in hopes of exciting the mercury vapor that way and instead just got a really cool flameout and plasma from the start circuit resistor!
Congratulations on 15. One of my first subscriptions on the platform alongside PhotonicInduction, V8Jagnut, Bigclive, and Aussie50 (RIP).
Speaking of photonicinduction, do we know where he went this time?
pretty cool how two of them lamps kept running once the arc tube ruptured allowing sodium vapor to be ionized / arc in the envelope then deposit the sodium metal? on the glass.
If it is sodium metal it will react with water.
if other metal probably won't react.
I have seen blown sodium lamps in the skip with a silver/black coated envelope with similar colours.
There is some mercury in there too. Hopefully the outer bulb doesn't burst too.
Congrats on 15 years of blowing electrical stuff up for fun and taking us along for the ride Rodalco2007!
3:37 not going to lie I jumped! :-D
In the words of photonicinduction... I popped it 🤣🤣🤣 great video mate
Love it. If you were local I'd give you a bunch of 1000 W HPS and Metal Halides to have fun with.
Congratulations on 15 yous of YearTube Ray, it has been a fun unpredictable journey, we lost some friends along the way R.I.P Aussie50, but at the end of the day, there are always microwave oven transformers.
We used to use the lamp cartridges inside the glass bulbs to sharpen knives.
Oh are they ceramic? I thought they were just quartz
i love how hps looks.
Congrats for the 15 years! Keep up the good content :)
Congratulations.
weird how the lamps have a "life" in hours. Driving it at higher power reduces that life. I don't know how they do it, but it's done on purpose. It fascinates me how closely it matches the hour time.
It's a tradeoff between light output/efficiency and lifetime.
Most likely you can calculate how long it takes to oxidize based on the amount of o2 molecules in the lamps atmosphere
@@TheRailroad99 yes but the lifetime is fake.
For others 15 and 15.. more and more 👌👍 great stuff
happy 15 years on you tube
That last one really held on!
Bro I love ur vids
Crazy cool👍💥
🙄
Super!
the insides of these bulbs are getting hotter than the sun.
Yeah agreed
Thanks, it was interesting. Could you please try to break one of those "silvertop" lamps underwater? There should be a reaction between sodium and water...
LED 1500 WATT panels are incredible
Like the 🌞😎 Sun
Lights up for miles
Ok
I'll put up a 1500W short arc xenon against any LED 1500 W panel. Fun with point- source lamps when they "expire" tho :)
@@totalrecone This comment reminds me of pictures I saw of maintenance workers replacing IMAX projector lamps.
They wore some quite serious protection gear.
@@Kalvinjj Totally agree. Those IMAX 15kW lamps could literally blow a hole in the lamphouse should they 'go off' while under operating pressure. I had a 4.5kW xenon blow during a performance and it took out the dichroic glass mirror, dented the Strong X60 outer shell and the anode lodged itself in the shutter of the projector. The explosion rang in my ears for two days after.
LEDs are definitely safer :)
nice...
Yes! Device tests!
Sometimes the leads in the base of the lamp will melt before the tube fails at these powers.
The fact that anyone knows this means they are a waste of oxygen
sounds like my wife reaches for to finish the job off
Nice poppage
How the hell did the glass not break?!
Switch one over to 200 VAC Mains once after starting. Talk about popping :)
4:03 Holy shit!
So strangely beautiful
@@hyvahyva LOL
Photoinduction-ish vibes...
👍🏻
I wonder what happens if you put double or more the amount of power on the power boost side, the outer glass shell might explode and glass will fly everywhere? I would like to see you do this again with more power when you get more free time.
I will do some on the capacitor bank when that project is completed.
Good stuff..!!! I' have one lamp of this type, but never tested it, ¿do they need an ignitor or just with the ballast will be enough? Thanks.
You spelled "lame" wrong
Hey man. I'm trying to make a setup like this. Can you help me make one like yours?
Im wondering that is it possible to connect two ballasts to run one lamp? 600+400=1kW?
Yes, try it out and check if the 400W ballast doesn't overheat, because the impedances are not the same.
that last one most eventful
Were these bulbs connected to 240V in series with the MOT primary? Or were they connected across ~2kV from the secondary winding?
The MOT's were switched in parallel with the normal 150 Watt ballast.
@@RODALCO2007 so if I understand correctly, the bulb itself had a voltage drop a bit less than 240VAC across it and was passing a few tens of amps (as shown on the dial) through the arc tube. Impressive!
The ballast normally limits the current to the lamp, otherwise it will self destruct as you can see in the video. A larger ballast means more current, more heat and failure of the lamp.@@deltab9768
@@RODALCO2007 makes sense. At first I was thinking the MOT’s secondaries were feeding kV to the lamp but it sounds like that’s not the case.
I think part of my confusion was being from the USA where 120V lighting circuits are very common. So they have a ballast that both boosts voltage and regulates the current.

Now, to fill the used bulbs with AA batteries and overcharge them. 🙂
Try starting without ballast.
How about some low pressure sodium light failures. And metal halide, fluorescent tubes And anything else that can be overballasted. Making things go bang is its own science.
I have only 1 failes LPS sox lamp which I will overballast at some stage. Done fluro's on MOT's and they go very bright, will do some more, stay tunes. The weather is absolute crap at the moment in Auckland.
Jet pipe overheat
Could you not have squeezed just one little wasp into one of thos bulbs. Not seen even ONE bee here in the UK this year. Too early for wasps but I bet those buggers turn up.
What was the point in all this lol
Esh
H P S. M H. M V. All junk. Led is king now.
No it’s not 😂
You should make a second video where you take those sodium coated bulbs down the nearest river or lake, smash them and then throw the pieces into the water.
Its not rocket science to see the results what would happen to the bulbs putting far too much power through them...... the bulbs would just burn out.
