Addy I found that site about year ago and wondered how well they would work. How long have you had them? Did you get the ones that can change colors?
They have been in the pond for about 3 weeks now, very well built, heavy duty, no real heat output that I can notice. They are just white light, I asked them for the brightest ones they have. I did not care for the color changing, this was mainly to see the fish in the evening while watching tv.
after many years of trying multiple brands of submersible lights I've finally decided to quit using them. IMO they make the fish swimm funny, many have issues with leaking, some put of large amounts of heat and others leak out small amounts of stray voltage. I found that outdoor halogen light hung 8-10" over the pond wotk really good for me, they show the fish up better at night, they don't seem to heat the water much but they do heat the air around them and will help reduce the chance of freeze over for those of us in the deep south and the attract bugs for the frogs enjoyment. I want to try LEDS done the same way on the new build and see how they do.
There is no voltage leakage, my hubby the electrician can pick up, ow he would ban me from the pond lol The heat even when on land it not tremendous, I am not home, but will get our infrared temperature reader and check it, when we get back to maryland. I put my hand right on the light, lit up and it did not burn me or even really feel hot. The pond shows not temperature increase with the led lights, the halogen are a different story. the fish do not seem to mind them at all. They just float around. We do not have them on all night just maybe 4-5 hours.
I have underwater ones that I had to pull out that I bought at Lowes and they quit working but now they decided to work outside the pond tucked in the rocks and shining out onto the pond. I don't turn them on much except when someone is coming over or am out sitting on the front porch in summer when warm which happens here rarely. Sounds like addy might have found some good ones.
I did a lot of research for them jw, so far really pleased with how they are working.
I sealed the LEDS also as I did not want to find out the hard way they leaked and since i had the silicon anyway why not .The only thing is i found my snails like to work more when it is a little darker and had to move the ones up by the waterfall so I'm not sure how they are going to react to the lights in the pond .I read where they prefer dark to work .So may have to do like JW and just turn them on once in awhile .
Mine are on a timer sissy, just for evening viewing ow the pond is dark, out in rural md, there is no light down there. I have the lights turn on right before it gets dark so there is not sudden bright light to scare the fish, it is just staying lighter for a while longer.
