E26, E27, E39 & E40 Edison Screw Lamp Holders – Medium & Mogul Base
E26, E27, E39 & E40 Edison Screw Lamp Holders – Medium & Mogul Base Socket Solutions
Yoeruyo's E26, E27, E39, and E40 lamp holder range covers the two most widely used Edison screw base families in global lighting: the medium Edison screw (E26/E27) for general-purpose lamps, and the mogul Edison screw (E39/E40) for high-wattage HID, LED, and high-pressure sodium lamps used in industrial and street lighting. Our holders are available in pendant, batten, panel-mount, porcelain, and keyless configurations to suit residential, commercial, industrial, and OEM applications worldwide.

Buying Guide – Selecting the Right Holder
- E26 vs E27 – E26 (26mm) is the North American standard; E27 (27mm) is the European/international standard. The 1mm difference means they are not safely interchangeable — confirm your market before ordering.
- E39 vs E40 – same rule applies: E39 is North American mogul; E40 is European/international mogul. Not interchangeable.
- Medium vs mogul – use E26/E27 for lamps up to ~300W; use E39/E40 for high-wattage HID and LED corn lamps from 150W to 1000W+.
- Housing material – thermoplastic for LED and CFL lamps; porcelain or ceramic for HID, HPS, and high-wattage halogen lamps generating high base temperatures.
- Wire gauge – 0.75mm²–1.0mm² (AWG 18–16) for E26/E27; 1.5mm²–2.5mm² (AWG 14–12) for E39/E40 high-wattage applications.
Frequently Asked Questions
Can I use an E27 lamp in an E26 holder?
E26 and E27 differ by 1mm in thread diameter. While they can sometimes physically engage, mixing them is not recommended due to safety and contact reliability concerns. Always use the correct holder for your market's standard.
What is the difference between E39 and E40?
E39 (39mm) is the North American mogul Edison screw standard; E40 (40mm) is the European/international mogul standard. They are not interchangeable. Confirm your market's standard before ordering mogul-base holders.
Do E39/E40 holders need to be ceramic for HID lamps?
Yes. High-intensity discharge (HID) lamps including metal halide and high-pressure sodium generate extreme heat at the lamp base. Porcelain or ceramic E39/E40 holders are required for safe, reliable operation — thermoplastic holders are not suitable for HID applications.
Are these holders compatible with LED corn lamps?
Yes. E26/E27 and E39/E40 LED corn lamps are direct replacements for CFL and HID lamps in the same base size. LED lamps generate significantly less heat, so thermoplastic holders are generally suitable for LED corn lamp applications.
Do you offer bulk pricing for OEM and contractor orders?
Yes. Yoeruyo offers tiered pricing for orders of 100 units or more across all base types and holder configurations. Contact us for volume quotations, mixed-SKU pallet orders, and distributor program details.
