First off, I am glad I found this site. The information everyone posts is invaluable to the newbie and professional alike. Here is my situation, I moved into a home with an existing system. Rather than leave as is I decided to do some research (wife calls it a flaw) and have determined there are too many issues to just re-bulb. The existing system has two separate single tap 600 watt transformers mounted indoors (one in basement and one in garage). The lights are daisy chained on one lead per 300 watt transformer. The well lights (5 on house and 3 on trees) are par 36 and the connections are rusted with a few melted/burned tubes. The two driveway lights are 13 watt incandescent bayonet base. There are also two bullet lights that i have no idea what they are supposed to shine on. Now that I have decided to redo it I am stuck on where to start. I should really purchase new transformers with multi tap connections so that I can hit the maples out front and light some elements in the back yard. Rather than do that i am going to keep it simple for now and just tackle the front areas closer to the house. I was going to rewire from each 300 watt leg with a hub system. I was going to stay away from the par lights due to the mulch bed and the issues with existing but i am not sure i can get the effect i want on the house and taller trees. What would you do?? Thanks in advance.
