So, I tried to count and there’s conservatively 20 lamps on the rooftop. There’s a Walmart near there, so I’m assuming that’s his lamp dealer. They have a bunch of bundled lamp sets (3 lamps in a set) for $50. That would put his lamp budget at around $350. I’m going to assume it’s a monthly cost as rain exists and it’s a safe bet that he doesn’t move them inside (they would be tripping over lamps all the time). That doesn’t include his extension cord, light bulb, or decorative ladder budget or any fees for filling the dumpster with lamps.
