Add instant ambience to your evening swim or pool party with the In-Ground LED Pool Light. This bulb screws into your in-ground pool's existing light socket, and its 231 RGB LEDs gradually transition through the entire color spectrum, glowing in thousands of colors each minute. # Bulb # Instructions Choose from five different effect modes to find the light that best suits your mood: white only, color mix, color lock, blue-green fade, or party mode. In party mode, the colors transition quickly through the color spectrum. No external control system is required, and since the In-Ground LED Pool Light uses LED lights, the bulb should last approximately 100,000 hours under normal operating conditions. This LED light is ideal for in-ground pools, but color-changing lights are also available for above-ground spas or 12-volt or 120-volt in-ground spas.
