I'm thinking about the lights outputs -
They will take quite a lot of amperage if they're all lit at the same time, so I'm thinking about having a 25% duty cycle or similar. That way only 24 lights can be active at the same time, consuming around 6A - unless my calculations are way off.
I should mention, this is using bulbs. Using LED's it will consume far less power.
The biggest problem is that I only got 8A fuses but hopefully there's larger fuses available.
Either that or I'll need to put the +5 VDC through multiple fuses, which requires a little work.
