We have Malibu landscape lighting and the bulbs burn out after only
about two months of service. They are very bright compared to my
neighbor's Malibu lights and he only replaces bulbs about once a year.
When the landscapers installed our lights they did not use the wiring
that came with the set. Instead, they used their own wiring which is a
much larger gauge resulting in less voltage drop by the time the
current reaches the lights. I am sure they thought they were doing me
a favor, but their generosity appears to have worked against the life
of the bulbs. Is there a simple solution to drop the voltage enough so
these bulbs don't burn so hot? Would a standard light dimmer for 120
VAC work to adjust the 12 VDC voltage?

I don't know volts from ohms, but helped a friend shop for those dang
Malibus. We had to select the right total watts to fit the transformer,
as I recall. If a bulb burned out, it was supposed to be replaced
quickly or the remaining bulbs got too much. Is the transformer right
size for size/number of bulbs?
