I have a question for those in the know about landscape lighting and electrical engineering in general. I have a pool and spa which each include a 12v light. Previously they were halogen bulbs which I have replaced with LED's. They are powered from the same Intermatic control box which houses the pump timer. The transformer is a 500w unit. Obviously this is way overpowered for the new LED's in the pool and spa. Because I have some power to spare I have started adding other LED lights inside my pool enclosure. I'm no electrical genius but I can do the math. From my research I've learned that the max wattage load should be less than 80% of the total wattage or around 400 watts total. Which brings me to my question. Is there a parasitic wattage load from the wire itself?
Thanks in advance for your replies.
