The up lights in question were working fine until I added a few more post lights to the end of the string so I dont think they are wired wrong. Whats got me puzzled is thet the last 3 post lights I added, which are a higher voltage then the up lights, are lit just fine. Same goes for the post...
I have about 250 watts in assorted light fixtures on a 300 watt transformer. All the lights are lit fine with the exception of the 3 uplights I have mixed in. They are lit but are very dim. Each are only 10 watts. The last 3 post lights in the string are fully lit.
