Porcelain G4-GY6.35 Halogen Socket with 6" Leads

Engineered for professional-grade lighting systems, the 03488B Porcelain Bi-Pin Halogen Socket delivers dependable performance in high-heat and high-wattage environments. Constructed from durable high-temperature ceramic (porcelain), this socket is built to withstand demanding thermal conditions without cracking, deforming, or degrading over time—making it an ideal choice for halogen lamps such as JC, JCD, and MR16 types.

This socket supports up to 750 watts and 250 volts, making it compatible with both low-voltage and line-voltage lighting applications. The socket comes with 6-inch 18AWG high-temperature insulated wire leads, ensuring easy and secure connections in enclosed or hard-to-reach fixtures. The leads are silicone-coated for enhanced flexibility and protection from heat and wear.

With spring-loaded contacts, it offers secure, vibration-resistant lamp retention and consistent electrical connectivity—reducing the risk of flicker or contact failure. The design accommodates pin diameters up to 1.5mm, ensuring broad compatibility with a comprehensive range of IEC 7004-standard bi-pin bases, including:

• G4 IEC 7004-72-3

• GU4 IEC 7004-108-2

• GY4 IEC 7004-72A-1

• GZ4 IEC 7004-67-3

• G5 IEC 7004-52-5

• G5.3 / GU5.3 / GX5.3 / GY5.3
