I have a 200 watt "Malibu" transformer and I want to connect 5 three
tier 12V lights and two landshap lighting 20W. should I use a smaller
wattage transformer? Do I have to use more lights to equal to 200
Also, I have 100 feet of 12 gauge wire do I have to use it all or can
I cut what I don't need off?
The wattage rating is the MAXIMUM you can use. Use a single light if you
wish...no problem...just a lot of excess capacity. You can use up to 10
You can cut the wire off, but tape./seal off the ends if it is to be buried.
Here's another bit of info from the Malibu FAQ page:
** Should transformers be used to their full capacity? **
Yes. As the load decreases, the output voltage of the transformer
increases. Therefore, the life of low voltage lamps will be shortened
unless the transformer is carrying close to its rated capacity. The rule
of thumb is to use at least half the transformer's wattage rating.

Nicolas, you're planning to use the 12 gauge wire from the house to
the transformer, right? You don't need heavy stuff like that for the
12v lights. No offense meant.
