Re: LED Xmas lights and X10.. the final solution...

["Steven Downin" <downin@xxxxxxxxxxxxx>]

I ran across the LED glow issue last year. I'm slowly changing outside
decorations to LEDs where possible. The $0 solution is to connect at least 1
miniature light set to each LED branch power feed.  This not a problem since
I have an intermix of LED and miniature lights.  This needs to done at the
controller end or before the LED strings.  The pass-through power
(string-a-long) on the LED string is rectified voltage (about 100 volts DC).

My decoration theme is candy cane so most of the lighting is red and white
(clear or frosted).  For years I'm made on own color schemes by
interchanging bulbs. However, this is not possible with LEDs.  For one
decoration I interwove the red and white LED sets using tiewraps.  My next
task is red/white LED icicles (sometimes called curtain lights).  There are
a few on the market but are way, way, way too expensive.  No easy solution
other than cut, splice, heat shrink, and keeping the polarity straight.

The colored LEDs are very bold in color.  However, the white LEDs have a
slight cold blue color when viewed outside in the dark.
