Given 2, 100 microF capacitors, AC or DC power source, any resistors, a switch, and a lamp (max voltage 5v). How do you make that lamp slowly power on to full brightness in 8-10 seconds. What would the circuit look like too?

I would propose circuit like this:
(simply and enough for your purpose)
Of course its a draft, you have to pick right power transistor according wattage of your light. Also ensure enough base current to fully open the transistor (after C charged) but not too much to force the Led current too fast, so choose the correct base resistor.
