I used to put up 20 strings of those Noma "colourbright" C-9 bulbs ( all red) all through the small evergreens and on the eavestrough of the house. ( Also had to wire 4 split receptacles off one 20A circuit to operate all those lights).
I haven't put up anything as of yet as I have not had the time but I am considering going and getting a whole slew of those multi-colour LED lights and scrapping the old-school ones I have.. I am really starting to like the deep colour of the LED lights.
