Performance metrics for the Peasur 140 LED system indicate a high failure rate associated with moisture ingress through the PIR sensor gasket. This structural vulnerability leads to corrosion of the 3.7V Li-ion battery terminals and permanent circuit malfunctions, such as "ghosting" where the light remains dimmed regardless of motion input. Technical specifications list the battery capacity between 1200mAh and 1800mAh, which may be insufficient to maintain the 140 LED array at full intensity for extended periods.
Material analysis confirms the use of a monocrystalline silicon solar panel with an efficiency of approximately 20%, though its small surface area limits energy recovery during low-solar-yield winter months. The housing is constructed from UV-sensitive plastic that is prone to yellowing. Aggregated data indicates the unit relies on an analog PIR sensor for motion triggers and a photocell for dusk-to-dawn logic, with no digital override capabilities.
The 270-degree lighting angle is achieved via a multi-faceted SMD 2835 LED array, which provides high lumen-to-watt efficiency but creates localized heat-soak within the enclosure. The IP65 rating is often compromised at the hinge and sensor seams, requiring supplemental silicone for long-term survival in high-precipitation environments.
- LED Count: 140 SMD2835 Chips
- Battery Chemistry: 3.7V Li-ion (18650)
- Illumination Angle: 270 Degrees
For installations where hardwired reliability is more critical than solar independence, the Karjoefar 100W Barn Light provides a high-output, mains-powered alternative.
