What did it cost to light the LED house in the movie, "Deck The Halls"? (Materials & Labor)?

Question

Majority of materiels were supplied by Color Kinetics.

Answer 1

I don't know the cost but LEDs are cheap when bought in quantity. The least expensive colors are red, yellow and green. Blue is high dollar. The power supply shouldn't be much unless you have a LOT of them (drain = 20 mA typ). Just watch your polarity and make sure to use a DC source rated at around 3vdc. Connect in parallel.
