How Long Do Lighting Fixtures Last? Warranties on fixtures and transformers range from one to 10 years, but fixtures made of brass, copper, or stainless steel should shine indefinitely.
In short “until it fails” as some of the transformers are still in operation after the legal retirement of plant engineers and technicians. When a transformer is operated under ANSI / IEEE basic loading conditions (ANSI C57.96), its normal life expectancy is about 20 to 30 years. The ANSI / IEEE basic loading conditions for Transformer are:

Frequently Asked Questions
How long does a light transformer last?
They operate at about 90 to 95 percent efficiency and can run for a very long time, anywhere from 20 to 25 years. They also are much more quiet, so you can place them close to the fixtures, rather than having to run wires a long way from the transformer to the fixture itself.
How long can low voltage wire run?
Lighting Tip: You can run 12-gauge about 100 feet without voltage drop issues as long as the total wattage of the fixtures on the wire is 100 Watts or less. Also check that your wire and connectors are listed for direct burial which helps prevent corrosion and other weather-related problems over time.

How to make longer wire runs from transformer to lights?
There are several factors that will allow you to make longer wire runs from the transformer to the lights. Increasing the wire size, using a higher voltage tap on the transformer and lowering the number of lights or overall wattage will allow you to make longer wire runs. Started!
