IMO, garden lights are inadequate because they get dimmer and dimmer as the night progresses. They are never bright as a proper anchor
light; then fade away. If y'all in Mexico
have found them useful, then hats off to you, but I detest them because people here think they substitute for a proper anchor
light, and in the wee hours of the morning, they are almost invisible!
In case you wonder about this, my worst experience was in the Burnett River, near the Bundaberg Port Marina, in Australia
, where we couldn't see boats at anchor who were using them for anchor lights! Only the [offensive] big spotlight could illuminate their boats....scary at a landfall.
