The Pentair Light Engine Kit (619818Z) is the OEM 2nd generation replacement color LED engine assembly for the IntelliBrite 5G Color LED Pool Light. If the color-changing function of your IntelliBrite 5G has failed or the light output has degraded, this is the service kit Pentair specifies for that repair. ⚠️ IMPORTANT: THIS IS A KIT — NOT A SINGLE COMPONENT This listing includes the complete light engine service kit: circuit board (PCBA), two thermal strips, uni-tension wire clamp assembly, and an off-white silicone gasket (8 3/8" diameter). All components are included together in one kit. ⚠️ IMPORTANT: VERIFY YOUR FIXTURE'S VOLTAGE BEFORE ORDERING The IntelliBrite 5G Color LED Pool Light is available in both 120V and 12V fixture configurations. Confirm your existing fixture's voltage before ordering. If unsure, check the label on your fixture cord or the original installation documentation. ⚠️ IMPORTANT: LICENSED ELECTRICIAN REQUIRED — NEC ARTICLE 680 Pool lighting components operate in a wet environment. Installation must comply with NEC Article 680 and all applicable local codes. This component must be installed by a licensed electrician or a qualified pool professional certified in electrical equipment installation. The light engine is the core LED circuit board assembly housed inside your IntelliBrite 5G fixture. It drives the color-changing and white-light output of the light. When the engine fails — typically presenting as loss of color cycling, no illumination, or flickering — the fixture housing and cord do not need to be replaced; only the engine assembly. This 2nd generation kit (applicable to fixtures manufactured from 2010 to current) restores full color LED performance using the OEM Pentair circuit board. Specifications Pentair Part Number 619818Z Part Name Light Engine Kit — Color, 2nd Generation Generation 2nd Generation (2010 to current) Gasket Diameter 8 3/8" (20.9 cm) silicone, off-white Quantity Included Kit (circuit board, 2× thermal strips, wire clamp assembly, gasket) Fits Into Brand Equipment Line Model / Part Number Notes Pentair IntelliBrite 5G Color LED Pool Light 619818Z 2nd generation light engine kit. Verify your fixture's voltage (120V or 12V) before ordering. Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Pro Tip Before ordering, locate the part number on the original light engine circuit board itself or in your IntelliBrite 5G fixture's installation manual to confirm this is the 2nd generation engine (619818Z) and not a 1st generation variant. The generation designation matters — installing an incorrect engine generation will result in improper fit or function. When servicing the engine, also inspect the lens and gasket assembly (619864 / 619864Z) for scratches or seal degradation, as the lens is removed to access the engine and is a common companion service item.
