Lotus 4" Square Deep Regressed Corrosion Resistant LED Downlight - 15W | LD4S-CPL
Lotus 4" Square Deep Regressed Corrosion Resistant LED Downlight - 15W | LD4S-CPL
The Lotus LD4S-CPL is a corrosion-resistant 4-inch square deep regressed LED downlight designed for installations where standard trim materials are not the best long-term choice. It combines the same clean, low-glare architectural look of the LD4S family with a rust-free polycarbonate trim built for harsher environments.
Purpose-built for ocean front soffits, saunas, and steam showers, the LD4S-CPL delivers premium light quality with 90+ CRI, flexible beam control, and the same compact no-housing-required installation platform used across the LD4S family. This is the right merchandising angle: not just another trim option, but a specialty solution for corrosive and moisture-heavy environments.
