Add instant ambience to your spa relaxation with the Above-Ground LED Spa Light. This bulb snaps into your above-ground spa's existing 12-volt light socket, and its 24 variable-intensity 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 Above-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 above-ground spas. A 12-Volt In-Ground LED Spa Light and a 120-Volt In-Ground LED Spa Light as well as a 120-volt In-Ground LED Pool Light are also available. The Above-Ground LED Spa Light will not work with spas that have dimming systems or electronic controllers.
