May not want to run AC and DC in the same conduit for any length, even if it is shielded.
You can get direct bury Cat5 that is shielded, on the cheap.
LED outdoor lighting is pretty cool, but a different type of light as R&R said. I like it tho.
Out lighting guy's are doing some tests with LED stuff for a city that want's to replace all the outdoor lighting, even the street lights. I am not hearing much on the positive side. Just have to see how it plays out.
Don,
I sent your info to our guy's after you PM'd me a while back. We do large projects like schools, hospitals and factories. Problem with LED in these applications is payback time. Bean counters look at this stuff
I personally like LED light, and will utilize appropriate amounts of LED light on my property.
Also, be careful on how far you try to shove DC Voltage. If Edison won the battle, I doubt that telephone poles would exist today, and the world may have run out of Copper by now
