Hey guys!
Recently I got an old lighthouse bulb which is called a 'Brandarislamp' here in the Netherlands
The type is a Philips 7504K, they were made to be powered by 70v and draw 60 amps, I hooked it up to a old PC PSU.
I started by using the 5v line from the supply, after a few minutes the filament lit up very little, then I connected the 12v line and there was some light, but a little bit dim. (just enough for me tough.)
I also tried to power it inmediately with the 12v when the filament was cold, but that tripped the automatic fuse inside the PSU.
After a while my PSU got too hot (the fan wasn't turning..) and it died...
What I want to do is make a new PSU for the lamp, so I can use it as a dim light, So I am wondering if someone could help me out with an idea for a power supply.
It doesn't have to be very powerfull, but it would be nice if it has some 'oomph' and could provide some decent light.
Also some general info about lighthouse bulbs is welcome!
Here I have some pic's from the bulb with 5v and 12v
