I have had a pair of these lights in my yard since Octoberish last year. I think I have them on the brighter setting. They are pointed toward the doors to give us some light if we are out late and forget to leave a light on.
On heavily overcast days they are noticably dimmer at night. I don't know how late into the night they stay on. I figured even if just a few hours, that would be a few hours of bugs for my fish (if they work to attract bugs).
I will report back if I ever get around to doing it. Plan was to put them about a foot above full pool. As water level changes, I guess I would get to test out different heights. Never really thought about different colors attracting different amounts of bugs. Planned to point them down into the water.
