Document: these lights light ou the waterfalls in our pond but also light up the tree fern and its Spectacular at night.Love them
They light up our trough fountain and makes the water dance on the rock wall behind, makes it look like flames dancing.
Give my pond just enough light to feature my stone wall and in pond water feature, with blue and green filters gave pond a warm look,  added the sound of running water, a relaxing atmosphere.
Also included are three sets of color light lenses (red, blue, green, yellow) which i have not yet used. I will post updates...as currently the lights have only been in use for about a week, with no issues or problems. Currently, I recommend these lights for small to medium size ponds...for above avreage accent lighting.
These seem well made and they work great in my small (7' x 8') pond. If you had a larger pond, the cord between the lights is only about 2 1/2 feet and probably wouldn't go all around the edge of your pond. The lights came with 4 different colored lenses (one for each light) which was nice. I am happy I purchased these.
Purchased these 30w lights to place in our newly installed 400 gallon pond, as a source of accent lighting for viewing the pond during the evening hours. Easy to set up and install. Simply plug in and go! Each of the lights is weighted on the bottom of each unit, and each light will sink and stay where you place it. No floating issues withthis product. Lights are connected by 3 feet of line between each light.
My waterfall/pond is only 80 gallons but this Halogen light set does the trick. I searched high and low for a submersible LED light set but reviews/price of those units were sketchy. These halogen lights are made well, have not leaked and come with 3 different colored lenses (cheap plastic) but have held up well. Lights are placed approximately 1 foot deep and dramatically change the color of the water and the waterfall :)
I purchased these lights and I regret that I did. Two of the bulbs blew out within the first three weeks of use. Replacing the bulbs is more difficult than need be. The light bulb requires too much force to go back in. It actually bends the contacts. The two new bulbs that I put it, blew out the second I plugged the unit in. There went 15 dollars in bulbs down the tubes. I walked the light set right over to the garbage can and threw them out.
We use the lights to provide accent lighting to two underwater plants, and the third simply sits on the bottom under our small fountain pointing upward...and completely lights up the moving waters of our pond fountain. Great lighting effect! I compared this set of lights to a comparable LED set....and these lights win hands down. Much brighter, heavier, better quality than the LED set I just sent back. They provide bright warm light, while completely submerged underwater in the pond/fountain.
We needed something for our small pond that we could leave on a timer. For the price, they work great.
