Recessed lights drop down into a 1" dia. drilled hole to give a clean flush look. Each light is constructed from a stainless steel bezel and a plastic, fully potted body. The solar panel can be positioned remotely using the 2 meter long lead. The 3 lights are separated by quick disconnects at a distance of 1.5 meter each. For longer runs, add up to two optional extension packs for a total of 9 lights running on one solar panel.
