Has anyone ever put a watt meter on the primary side of a typical Malibu lighting transformer to determine how much power is saved by simply changing the bulbs on the string to LED's? Just curious if anyone has some real number comparisons.
I wouldn't think the cost savings would be that great considering the transformer losses and price of LED bulbs. And wouldn't Malibu already have drop-in LED bulbs to retrofit their legacy products if there really were great payoff?
Also how do LED bulbs hold up to 6 months of winter?
