Landscape Lighting Wiring

I'm planning to run 12-2 home run wires from a 600W multi-tap transformer to six hubs. The hubs will be located between 10' to 100' from the transformer. I then want to run 25' of 16-2 wire to three or four fixtures from each hub. Each fixture will have an MR-16 20W bulb and already have approximately 36" of 18-2 lead wire pre-attached. Can I mix these three sizes of wire and should this approach prevent voltage drop? Alternatively, I could use the T method of wiring each group of three or four fixtures. I understand that with a group of four fixtures, I can hook up the 12-2 home run wire to a T connector placed between the middle two lights and then continue to run the 12-2 wire to both fixtures on either side of the T connector. But,how do you hook up the T method for a group of three lights? Do you wire the home run wire with the two wires running to either side and with the lead wire from the middle fixture?

I would would stick with 12/2 wire for the secondary feeds and 10/2 for your home runs back to the transformer.  I like to never put more than 100 watts on 100 feet of wire to just be safe.  With the 10/2 you can double that total.  If you use 12/2 DIRECT BURIAL CABLE on the secondary runs as mentioned, you can use the supplied CONNECTORS to attach each 18/2 fixture lead to the cable.  Why don't you check out our handy POWER CABLE CALCULATOR for more information.
