Extension does the job.
Great customer "care" -- I purchased just two extensions but was sent four, two of each "coupling" configuration that might be required depending on the particular fixture involved. Thoughtful and unexpected. The service at time of sale (by phone) was patient and professional. Nice way to do business. The two extensions (making a six meter long lead to run from solar panel to fixture) work as intended.
Best UsesExtending distance solar panel can be placed from fixture.
