Add instant ambience to your spa relaxation with the In-Ground LED Spa Light. This bulb screws into your in-ground spa's existing 12-volt light socket, and its 54 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 Spa Light uses LED lights, the bulb should last approximately 100,000 hours under normal operating conditions. This LED light is ideal for in-ground spas requiring 12-volt bulbs. For spas requiring higher voltage, a 120-Volt In-Ground LED Spa Light is also available. An Above-Ground LED Spa Light and a 120-volt In-Ground LED Pool Light can also be purchased separately.
