I bought a used 1000w metal halide grow light cheap off Craigslist because the grower switched to LEDs. Mounted it in the ceiling in my basement. Doesn’t take any special electrical wiring.

Put a couple of lawn chairs down there. I run it 1-2 hours day, usually right at sunset. It’s so bright you literally have to wear dark sunglasses. It was a real lifesaver for the emotional health of my spouse. The kids love it too, they also wear shades while they play or read. Even the neighborhood kids like to come over. It totally illuminates a 20 x 20 room. Where we are electricity is $0.074/KWH so for 15 cents a day this has been a huge boost to the family’s mental well-being.
