Trouble with Outdoor Lighting
I hope a question regarding low-voltage outdoor lighting is welcome here.
The outdoor lighting system I installed myself many years ago is having problems. The transformer (and therefore, the lights) keeps cycling on and off. The customer service tech I spoke with said the transformer is overheating. It's a Malibu 120-watt transformer and I have 120 watts worth of lighting on the system. He told me that it could be problematic to max out the wattage. He also told me that lights should not be attached to the end of the line, but instead, an extra foot of line should follow the last light. This would mean digging up the lines and splicing on an extra foot of cable, and since the line tees, ending in two places, the chore is doubled.
Does this sound like good information? After going online, I've found that all these Malibu transformers have many, many complaints and one-star ratings, so before I go digging up the yard I wanted to get some feedback on the soundness of the customer support person's advice, particularly the foot of extra line bit.
