Low-voltage lighting | Problems and solutions
Low-voltage lighting
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.
