Low-voltage lighting | Problems and solutions
The only real concern for the owner of a low-voltage system is the replacement of burned out lights. The most commonly used bulbs (such as MR-16 and Par 36 bulbs) have a life expectancy of anywhere from 1000-1500 hours depending upon wattage and type of bulb. Standard incandescent light bulbs produce a soft yellowish light. Halogen bulbs produce a clean, bright white light, and while they cost more, they also last longer than incandescent lamps. Halogen bulbs (or ‘lamps’ as they are called) do need careful handling — use a cloth or gloves when replacing as oil from your skin can shorten lamp life.
Replacements
When a lamp burns out replace it with the proper bulb — a lamp of higher wattage may overload your transformer and cause voltage drops (lights will dim) or may tax the entire system.
Replacement lamps may be purchased through:
- Lighting Specialties (Portland)
- Horizon Irrigation (several locations)
- Pacific Lamp (Beaverton)
- United Pipe and Supply (several locations)
Simple Problems and Possible Solutions
If a single light doesn’t come on ...
bulb may be burned out
If all lights don’t come on ...
check to see if the transformer is plugged in
check for a burnt fuse in the transformer
check the timer on the transformer for the correct setting
Caution
Please be careful when digging around night lighting. While there is no chance of electrocution from cutting a wire, low-voltage wiring may be just 2 – 3 inches below the surface.
