What kind of power cable and transformer should I need?

e.g Suppose there is a set of 4 path lights (each 3W) and 2 flood lights (each 4.5W) need to be installed in the garden, How to choose the cable and the transformer?

1. Add the individual light fixture wattages for all lights. 4*3W+2*4.5W=21W

2. The typical distance between two lights is 6-8 feet, but closer or farther is ok too. Based on the above diagram, 6 lights total watts in 0-60 should choose 75-100ft 16AWG power cable.

3. Transformer is large enough to support the Total Fixture Wattage, it should be the best usage within 80 percent of the rated capacity. So in this case a 45W transformer is enough.

Note: A transformer that is too large for the load may overdrive the lamps which will shorten their life spans.
