A local club is building a wall of those 12VDC LED lamp clusters. Calculated DC Amps is a little less then 40 Amps after measuring one lamp hooked to a power supply and measuring the DC current.
Any suggestions on how to proceed with this project? Parallel MOSFET's? One really big IGBT? Really big bipolar power transistors?
Figured I would use a 555 for timing and drive the gate(s)? base? through a high speed optoisolator.
