Outdoor lighting problems explained
Outdoor lighting problems driven by environmental exposure and conditions.
Dead insects return inside the light even after you empty the cover and fasten it again. The useful first check is whether the affected chamber is designed to close completely. An intentional opening calls for a different response than a displaced gasket or loose cover. A lantern can look enclosed from the front while remaining … Read more
An outdoor light still turns on, but the planting bed or walkway it illuminates looks weaker than before. In daylight, the lens has pale spots or a chalky film. Sprinkler deposits may be obstructing and scattering light before it reaches the intended surface. The useful test is whether compatible cleaning improves both the dry lens … Read more
The sprinklers finish, an in-ground light’s lens looks cloudy, and the fixture still illuminates that evening. That combination does not tell you whether irrigation water entered the housing. It also does not establish that the fixture’s protection is intact. Start by distinguishing moisture on the outside of the lens from haze beneath it and water … Read more
An outdoor light is weatherproof only when the fixture rating, gasket, cable entry, junction box, and mounting angle all match the water exposure it actually receives. The first meaningful checks are simple: is the light listed for wet locations, does the gasket still compress evenly, and can rainwater drain away instead of sitting in the … Read more
An outdoor post light that stops working is usually a power-path problem before it is a fixture-style problem. The first useful checks are whether one post is out or several outdoor lights failed together, whether the failure followed rain or irrigation, and whether a photocell needs 30–60 seconds to respond after being covered. If the … Read more
An outdoor wall light that stops working is not automatically a bad bulb. The bulb is the fastest check, not the most reliable diagnosis. A better first split is timing: did the light fail right after rain, trip a GFCI, flicker for several nights, or stay dead even with a known-good bulb? If it works … Read more
When an LED flood light stops working right after rain, the most likely failure is usually not the LED chips. It is moisture reaching the driver compartment, the junction box, or a weak wire connection. If the flood light works again after drying, suspect a seal, cable-entry, or junction-box leak first. If it stays dead … Read more
Solar lights do work in winter, and that is the first thing most people get wrong. What usually changes first is runtime, not whether the fixture is “broken.” A light that stays on 8 to 10 hours in summer may only manage 4 to 6 hours in winter because the charging window is shorter and … Read more
