Buying Guide
Light type and power: Choose rechargeable, battery-powered, or wired options based on installation location and maintenance preferences. Rechargeable units minimize ongoing costs; wired lights offer consistent performance for permanent installations.
Voltage and compatibility: Verify voltage (12V vs. 120V) and niche compatibility (6-inch, waterproof ratings) to ensure a proper fit with your spa or pool. If replacing existing lights, confirm the exact model compatibility (Pentair, Hayward, Jandy, etc.).
Color and control features: If ambiance matters, prioritize lights with color-changing modes, presets, and remote control. Check remote range and whether the remote is waterproof or needs direct line-of-sight for reliability.
Durability and seals: Look for IP68 waterproofing and corrosion-resistant housings (stainless steel or high-quality plastics). Submersible lights should withstand continuous water exposure and, if used outdoors, saltwater or chlorinated environments.
Installation: Consider whether the unit is designed for easy DIY installation in existing niches or requires professional help. Check for adhesive strength, surface compatibility, and included mounting accessories.
Power considerations: For permanent spa upgrades, confirm electrical compliance with local codes and ensure that any 120V lights are installed in accordance with safety standards. For temporary setups or decorative use, cordless options may be more convenient.
