It. Isn’t. Easy.
You have to go in with a plan. Think about where you and other people see the pond from, where the lights should point, and how you want your pond to look.
Even then there’s still a major problem: the water.
Water bends lights like kids bend bendy straws. The light can end up pointing in a direction you don’t expect or like, so that’s what makes it a trial-and-error process. The best thing to do is use a waterproof flashlight as a stand-in and test out where the water points the light.
As for the right number of lights, it’s about ½ to ⅓ more than most people guess. Rocks, the pond liner, and the surrounding area tend to be dark enough to absorb the light, meaning you’ll need more lights than you think.
Danny knows that will cost more but it’ll be worth it when Danielle sees their pond lit up beautifully.
