[Photonicinduction] purchased a very very bright light. This 20,000 Watt half meter tall halogen will just about light the back of a person’s skull with their eyes closed. These are typically used to light film sets.
Most people couldn’t even turn such a light on, but [Photonicinduction] is a mad scientist. Making lightning in his attic, it’s easy to mentally picture him as the villain in a Sherlock Holmes novel. Luckily for us, if he has any evil tendencies, they are channeled into YouTube videos.
He gives a good description of the mechanical and electrical properties of the light. The body is as one would expect for an incandescent light. A glass filament envelope with the filaments supported within. The envelope is evacuated and filled with an appropriate gas. This light is dangerous enough that the outside must be thoroughly cleaned of fingerprints to keep a hot-spot from forming, which could cause the lamp to explode.
After some work, he managed to convince himself that the filaments within were not, in fact, garage door springs, and gave a demonstration of their properties. For example, their resistance goes up as they are heated. In order to keep from tripping the power supply, filaments this large must be preheated. Failure to do so passes a very large number of amps.
The next step was to hook the lamp up to his home-made 20 kW power supply. He gives a good demonstration of just how bright it is. Within seconds he’s sweating from the heat and definitely can’t even open his eyes to see with the tiny sun occupying the center of his abode. Video after the break.

Nice…. so I’ll be needing 6 to induce the tube… and they’ll take double the power pulsed right? ….. I’ve just had this awesome idea for converting a Chevy Volt into a laser cannon.
Every time I see his videos I think about all of the “Close Encounters” type experiences his poor neighbours must have had.
After this 20kw lamp, I wonder if 911 received numerous calls about the sun crashing into the neighbor?
I doubt it, he lives in the UK where we are a bit simple and so only have to use one number and dial 999. :)
In Russia it’s 000

The french got it right! As far as i see we use these lamps on lighthouses. but you could also use them on underground/protected/space gardens for a total of 10-20square meters, couldn’t you? The sun is only at around 1.4kw per square meter
He has a video of running a huge high pressure xenon lamp from an inverter welder at max of what the welder can give…given the higher efficiency AND efficacy of HP xenon, that was probably brighter…
I had the CC (automagic YouTube parsing) up on the screen, and it’s interesting what it made of his accent… Yes, “that’s a lot of hate” coming off that tube, enough to drive you out of the room.
That’s brilliant – I just turned it on and got: “It’s like having a bum fly me to the moon” (“it’s like having a bonfire in the room” for those that couldn’t understand his accent)
This would come in handy when I’m looking for… anything really.
Where’s the new moon? Ohh, there it is!
xkcd says that it cannot be done, but I’m pretty sure [Photonicinduction] could!
That’s no moon…
There are no next door neighbors as chill as Photonicinduction’s.
Chill huh? You sure that shivering isn’t out of fear? ;-)
Or quite as tanned in winter.
I always want a lamp like that. So i can make a searchlight and also call Batman
I feel like he ought to get onto these pages more often. His homemade power supplies are unquestionably awesome.
Definitely the correct mix of “that’s cool!” and “I’m not entirely sure that’s safe”
I think he need an electric chair in that room so he has a place to sit!
…until he runs 1000 volts through it!
8 garage doorsprings instead of a filament :D
Sorry, but it’s true!
Don’t fall in love with this one, you’ll get burned!
I could command respect if I had a serious podium like that, with a serious chrome lever. That makes a VVVZZZZVVVVCH noise.
I have to wonder where [Photon] got that big, bad bulb and for how much. I’ve seen them for as little as $1800 and as much as $6000 online, and I can’t imagine that even he would be willing to pay THAT much for a cool light show. Then again, this is [Photonicinduction] we’re talking about…
Oh, and kudos to [Packrat] and [Sheldon] for suggesting turning on the YouTube CCs. I needed the laugh.
Someone should tell him that the projector on his wall should be mounted upside down so it does not have to be at a nasty steep angle with a ton of adjustment. Those cheap portable projectors are designed to sit on a low table or be upside down on the ceiling or wall.
One.question, how on earth does one procure 20kw without blacking out the local area.
Note to self welding goggles required.
Multiple welding goggles and sunglasses, and one of those ‘volcano suits’.
In the US, houses are commonly equipped with 100A service (or at least 200A if using electric heating, cooking, hot water), at 240/120V split-phase. 100A x 240V = 24kW right there; just shut off enough other stuff to keep it below that.
I’m pretty surprised the camera did not melt.
The failures even a 500-1000 watt lamp can produce are energetic enough that running this lamp without an enclosure is an exercise in… bravery, if nothing else.
He’s got practice in that sport…
i always wondered what it would be like taking a slow stroll through a (thick) forest at night (in the dark) and suddenly THIS thing switches on, slightly off the path/trail …
quite the sh*** and giggles :D
Does anyone know how bright this is, in lumens or candle power?
