Landscape Lighting Voltage Issue has me entirely baffled
Getting to the meat of it, I have a 200W Transformer. I hook up a 12/2 AWG to the 15W output, and voltmeter shows 14.8V (Great). The run is about 8 feet. I hook up 1 Kichler LED light and the voltage drops 4V. (not Great)
Tried different 12/2 cables - same thing.
Tried a 300W Transformer. Same thing.
Tried a different light with the same type of LED bulb - same thing.
Each time, I get a proper reading up to the point of adding the light.
The only thing I didn't change was the brand of bulbs. Would a type of LED bulb cause a 4 volt drop? What if the bulb says 12V and it is connected to the 12 gauge wire coming out of 15V, would that make a difference?
THE BIGGER PICTURE: I had my daisy chain working just fine with a VERY long run (over 250 feet with 12 Gauge, and then half of them went out. I found the point on where the last light went on, and nothing after that and that is when I started trouble shooting. And part of that troubleshooting was to add another transformer (the 200W) and shorten the run to 8 feet and STILL the voltage drops after that first light was added. The ONLY thing I can even think of is it is the actual bulb that is causing the issue, but I have swapped out the bulb for the same brand of bulb and the same thing happens.
I am absolutely baffled. Any insight would be greatly appreciated.
