Hi, all.

I have a bit of a strange request.  At work, I have a device that I have to repair that uses 400 multiplexed itty bitty incandescent lamps (10 rows of lights, each with 40 lights).  They each use 5V at 300mA when they're on (they're actually 1.5V lamps, but they have a 4R2 resistor and 1N4002 diode in series with each one to make it compatible with 5V.  I know, it's inefficient to do it that way, but that's the way they did it, and my timeframe is a bit tight to be modifying it now).  

Anyone know where in town I can get a power supply that could supply 120A at 5V?  Alternatively, I can power each of the 10 banks of lights individually, and use multiple smaller power supplies.

Any advice with this is appreciated.  Frankly, I'm stumped.

Thanks
-John C.
