I’m looking for cheap and easy ways to light up tombstones as well as some yard props in my haunt. I’ve got about 25 tombstones and need bulk lighting that is waterproof. I’ve used those LED color changing puck lights before, but you have to turn them on and off every night and they only have about 10-20 hours of light per 3 AA batteries, so those get pricey over a month long scene. I have low voltage landscape lights throughout the yard year round but can’t find mini light fixtures that can display different colors cheap at all. Would love something that can display whatever colors or color I need plus has a 4-6 hour timer. Oh, and I’m not very technical at all! Am I asking too much here??
