Guidance from Gary Duff Designs

Decades of experience have taught us a few things, here’s what most clients want to know before we start.

  • We design architectural, landscape, and ambient lighting, everything from path lights and garden lighting to pool illumination and accent lighting that enhances your property’s design.

  • Lighting should enhance, not overpower. We use low-voltage LED outdoor lighting and precise fixture placement to highlight texture and movement, never the light itself.

  • Yes. Every fixture is chosen for coastal durability, resisting salt, wind, and seasonal changes common across Long Island, NY.

  • Absolutely. We design with FX Luminaire smart lighting controls, allowing you to adjust timing, color, and brightness from your phone or home system.

  • Every property is different. The investment depends on layout, materials, and technology. During your consultation, Gary Duff Designs will provide clear recommendations and options to create lighting that fits your home, lifestyle, and goals.
