Arc table lamp from the LCD projector and I used the lamps existing wiring. So let me turn this on and while it's warming up I'll open the box up and show you what's inside the box there, so I use this cardboard box as an enclosure just because it was available and its cardboard is easy to work with. So here we have the two boards from the original projector and what I did was I bypassed the interlock here.
It had both a thermal interlock and a mechanical switch interlock, which I just shorted out and then the actual power supply board for the lamp itself had an optical input on this side. And if you look closely down at the consolatory x' there, you can see I've shorted one out so that the power supply board thinks that it's always getting the signal to turn on.
So surprisingly, this lamp cord between the power supply and the lamp was able to withstand the high starting voltage. I think the starting voltage could be many kilo volts, but after the arc strikes, the voltage is pretty low and the current is high. And then I just used a lamp cord with an inline switch here, just to turn the whole mess on. So this is a 270 watt light pretty bright.
Let me just aim it up at the ceiling kind of see what that looks like when we stop the camera down a bit, so you can see compared to what the brightness of that fluorescent lamp there, the spot from the from the arc grill from the arc. The lamp is pretty bright, so I mounted the bulb in there with some silicone tubing and some wire and the wire and silicone tubing can take the heat, but the paint inside the lamp housing cannot so after it runs for about five minutes.
