Yes. Lumien rates its brass underwater fixtures IP68 and supplies a 30 ft lead to reach dry ground.
Is a transformer included?
No. It runs from a remote Lumien 12-15 V low voltage transformer, sold separately.
How do I size the transformer?
Add up the VA of every fixture on the run and choose a Lumien transformer with headroom; Lumien publishes the VA rating of each fixture.
