The average cost to install outdoor or landscape lighting is around $4,000, with most projects ranging from $2,000 to $6,000. The total cost can vary widely depending on several factors, including the number of fixtures, design complexity, and the type and quality of the lights used, such as wall sconces, pathway lights, or lamp posts. Other factors that influence the price are the square footage of the area being lit, the amount of electrical work needed, any required excavation or trenching, and local permitting costs. For specific types, you might pay around $100 for pathway or string lighting and up to $700 for lamp post lighting.

High-quality landscape lights that are hardwired and properly maintained can last for 10 to 25 years or more. You’ll usually get a longer lifespan from soffit lights and wall-mounted lights that aren’t directly exposed to the elements or prone to damage from foot traffic or vehicle traffic. Solar-powered and battery-powered lights often won’t last as long, but you can still expect a lifespan of five to 15 years.

One possibility is that they aren’t getting enough sunlight during the day, which could be due to a lack of sunshine in your area or trees blocking the solar panel. Alternatively, if the solar panel is dirty or the batteries are dying, your solar lights might not operate at full brightness.

Yes, animals can trigger motion-sensor lights. In fact, this is a reason why some homeowners install motion-sensor lights, to catch sneaky little critters looking through the rubbish for a midnight snack. There are sensitivities to animal detection though, so you may want to look for an option that avoids animal detection as much as possible.
