Color Changing LED Pool Light 1.5" Fitting 12V AC Submersible Spa Light with 14 RGBW Modes, IP68 Waterproof, Pentair Compatible, 50FT

[TOOL-FREE 1/8 TURN HERMETIC LOCK]: Installation is quick and foolproof. Using the specialized installation tool, push the light inward and apply a simple 1/8th clockwise turn. You will feel a definitive stop point, ensuring the locking tabs are perfectly aligned and the unit is hermetically sealed against water intrusion without the need for complex hardware.
[STRICT 12V AC POWER REQUIREMENT]: Built for long-term stability, this fixture requires a dedicated 12V AC industrial/magnetic transformer (toroidal or square). To protect the internal LED circuitry and ensure a 30,000-hour lifespan, absolutely DO NOT use electronic transformers or DC power supplies, which will cause permanent fixture damage.
[IP68 WATERPROOF & INTELLIGENT MEMORY]: Fully sealed and pressure-tested for continuous submersion at a recommended 700mm depth. The smart built-in memory function automatically recalls your last saved color setting when powered on. For a quick reset, leaving the switch off for more than 5 seconds will automatically default the system back to the energetic 'Party Mode'.
