Important Notes
- Maximum lighting time is listed by the supplier as up to 48 hours or more; actual run time will vary depending on charge level, usage and operating conditions.
- Solar charging time and performance depend on sunlight conditions and panel exposure.
- The supplier page includes a generic qualified-electrician installation note; this should be confirmed before publishing, as it may be standard boilerplate rather than a lantern-specific requirement.
