You can set the mood of your pond by using lighting.
You’ll set a more relaxing atmosphere by brightening the other areas: the pond bottom, a stream, and more calm areas.
Skimming a still surface area with light can create a calm mirroring effect.
If you want a more lively feel, illuminate areas where the action is: waterfalls, aerators, anything with movement. This includes anything around the pond as well, like plants.
For waterfalls, you can position a light to skim the water’s surface so everyone can see the rippling water
You can make them blend right in with proper setup. Nobody should be able to easily see the wires and fixtures.
But you may find this hard if you have an incorrect amount of pond lights.
The Correct Amount Of Lights
There isn’t a correct average number of lights for ponds.
Everyone’s water feature is slightly different.
You may need to get more than you think because water breaks up light, so plan on about ⅓ more if not ½. This is especially true if the material you are working with (rocks, liner, the pond surroundings) are dark because dark materials absorb light.
Let’s get into what makes underwater pond lighting so tricky.
Underwater Lights Can Be Tricky
Water can bend light like a strongman can bend a skillet: easily
This means the light may not go exactly where you want it to.
You may have to play with the angles until you find the ideal look for your pond. Just make sure there isn’t any glare going anywhere.
The lights can reflect into your neighbor’s home or be blinding from certain angles. A night test can ensure proper placement and angle and tell you which fixtures need adjusting.
After some practice, it can become easier to find the right placement.
But you probably don’t want your pond lights interfering with your pond fish.
Lights and Pond Life
Nobody wants to accidentally boil their koi.
You won’t be in danger of that no matter how many lights you use. But, you can end up raising the temperature too much and hurt your fish.
They don’t deal well with constant, large temperature changes. Fish also need some areas to remain dark and quiet for them to escape to. It’s hard to hide from nocturnal predators in what basically becomes a lit up fishbowl.
But done correctly, adding LED lighting can transform your pond.
You will need to maintain it to keep it looking good.
Maintaining Your Underwater Pond Lights
Like with any other landscape feature, maintenance is key:
Plants grow over the lights
Lenses get cloudy
Cords can get cut
And many other occurrences can happen.
You can help prevent this by maintaining your water feature lights every 3-6 months. This way they’ll have a better chance of staying bright and working longer.
This can mean spending less time and money on your pond in the long run.
