Custom Waterproof Outdoor Downlights for Commercial Lighting Projects
What Makes the DEP Series Different
The DEP Series is our answer for architects, distributors, and contractors who need reliable waterproof outdoor downlights that work in wet locations without the bulk of surface-mount fixtures. Unlike standard indoor downlights that warp or short out in humid conditions, these units are built from die-cast aluminium with a tempered glass lens — materials that resist corrosion and thermal shock. This is what sets a proper waterproof outdoor recessed lighting solution apart from consumer-grade alternatives.
I often get asked by hotel project managers: “Can I use the same downlight in the lobby and the pool area?” The honest answer is no — but the DEP Series comes close. With an IP-rated seal, COB LED downlight chips delivering CRI>80 (or CRI>90 on request), and four beam angle options, you can maintain consistent light quality across both dry and wet zones of a project.
