I am a self procliamed awsome lawn guy. however, I have run into a snag with some lighting issues. I need to install some lights in front of one of my complexes. It seems that in my contract for landscaping repairs and maint., I failed to protect myself from hard wired electrical desplay. All I need to do is install six ground level lights directed upwards into six seperate trees. There is power coming from somewhere to existing lines from a previous lighting system. the lines were descovered capped with wire nuts and have power at night. I immagine they are wired to a nearby street light and are controlled by the street lights photo cell because the lines are hot at the exact time the light comes on. Will I be ok connecting the new lights to this system if I seal the lines in conduit? Is there a good book for lighting if this isn't a field i want to persue but just need a hint once and a while for such problems? btw subbing out wouldn't be an option.
