The holder uses a ceramic body rather than plastic, giving it resistance to heat and mechanical stress where low-voltage MR16 downlights operate continuously or on frequent switching cycles.\u003c\/p\u003e\n\u003cp\u003eDesigned for low-voltage downlight installations in residential, retail and commercial environments, the holder connects to existing 12V drivers or transformers via two 0.5mm² heat-resistant fly leads. The 90mm lead length allows the holder to be positioned inside a ceiling void, recessed fitting or track housing with sufficient cable run to reach a terminal block or driver output. The GU5.3 pin spacing is compatible with all standard MR16 halogen and LED lamps rated for 12V operation.\u003c\/p\u003e\n\u003cp\u003eThe ceramic construction tolerates operating temperatures higher than plastic equivalents, reducing the risk of socket deformation or cracking under sustained heat from halogen lamps. The two-pin push-fit socket grips the lamp securely without tools, and the fly leads terminate in bare wire ends ready for connection to screw terminals, wago connectors or inline terminal blocks depending on the installation method.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLead length\u003c\/td\u003e\n\u003ctd\u003e90mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e0.5mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitting\u003c\/td\u003e\n\u003ctd\u003eMR16 (GU5.3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage lamps does this holder take?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MR16 (GU5.3) fitting is designed for 12V low-voltage lamps, both halogen and LED. It must be connected to a 12V driver or transformer — do not connect it directly to 230V mains.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used with LED MR16 lamps?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The holder accepts both halogen and LED lamps with the GU5.3 pin base. Ensure the driver or transformer is rated for LED loads if using LED lamps, as older magnetic transformers may not be compatible with low-wattage LEDs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow are the fly leads terminated?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 90mm leads are bare wire ends. They can be connected to screw terminals, wago connectors or inline terminal blocks depending on the installation setup. The 0.5mm² CSA is suitable for low-voltage runs up to approximately 2m from the driver without significant voltage drop.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy use ceramic instead of plastic?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCeramic resists higher operating temperatures than plastic, reducing the risk of socket deformation or cracking where halogen lamps generate sustained heat.
