Yoeruyo's G24, GX24, G23, and GX23 lamp holder collection covers the full range of PLC-type compact fluorescent lamp bases in both 2-pin and 4-pin configurations. These sockets are among the most widely specified bases in commercial downlights, office troffers, retail display fixtures, and OEM luminaire manufacturing worldwide. Our holders are available in horizontal, vertical, angled, and snap-in panel-mount configurations, with thermoplastic and ceramic housing options to suit every application.
Base Type Reference Guide
| Base | Pins | Pitch | Ballast | Typical Wattage | Key Market |
|---|---|---|---|---|---|
| G23 | 2-pin | 23mm | Magnetic or electronic | 5W–11W | Global |
| GX23 | 2-pin | 23mm | Magnetic or electronic | 5W–11W | Global |
| G24d (G24d-1/2/3) | 2-pin | 24mm | Magnetic or electronic | 10W–26W | Global |
| G24q (G24q-1/2/3) | 4-pin | 24mm | Electronic only | 10W–26W | Global |
| GX24d | 2-pin | 24mm | Magnetic or electronic | 20W–70W | Global |
| GX24q | 4-pin | 24mm | Electronic only | 20W–70W | Global |
2-Pin vs 4-Pin – Critical Differences
- 2-pin bases (G23, GX23, G24d, GX24d) – compatible with magnetic or electronic ballasts. The lamp's internal starter is integrated, so only two pins are needed for power connection.
- 4-pin bases (G24q, GX24q) – require an external electronic ballast. The four pins carry separate filament heating and power connections, enabling faster starting, better efficiency, and longer lamp life.
- G23 vs GX23 – same 23mm pitch, different base skirt geometry (round vs rectangular). Not interchangeable.
- G24d vs G24q – same 24mm pitch, different pin count (2 vs 4). Not interchangeable despite similar appearance.
- GX24d vs GX24q – higher-wattage variants of G24d/G24q for 20W–70W lamps; same interchangeability rules apply.
Application Scenarios
- Commercial downlights & recessed fixtures – office, retail, and hospitality ceiling lighting with G24/GX24 PLC lamps
- Office troffers & panel lights – G24q 4-pin electronic ballast fixtures for energy-efficient office illumination
- Retail display & accent lighting – compact G23/GX23 fixtures for merchandise display and architectural accent
- Industrial & commercial high-bay – GX24d/GX24q high-wattage PLC fixtures in warehouse and factory environments
- OEM luminaire manufacturing – panel-mount and snap-in holders for production-line integration across all PLC base types
- LED PLC retrofit projects – G24d/G24q holders compatible with direct-fit LED PLC retrofit lamps (ballast bypass may apply for 4-pin)

Buying Guide
- Step 1 – Identify pin count: check the lamp base — 2-pin or 4-pin determines the socket type before anything else.
- Step 2 – Confirm pitch: G23/GX23 = 23mm; G24/GX24 = 24mm. Measure or check the lamp datasheet.
- Step 3 – Check wattage: G24 covers 10–26W; GX24 covers 20–70W. Match the socket's rated wattage to the lamp.
- Step 4 – Ballast type: 4-pin sockets require an electronic ballast; 2-pin sockets work with magnetic or electronic ballasts.
- Step 5 – Mounting orientation: horizontal for ceiling downlights; vertical for wall-mount; angled for directional fixtures.
Frequently Asked Questions
Can I use a G24d socket with a G24q lamp?
No. G24d (2-pin) and G24q (4-pin) are not interchangeable despite sharing the same 24mm pitch. The pin count and ballast requirements are different — always match socket to lamp base type.
What is the difference between G24 and GX24?
G24 covers lamps from 10W to 26W; GX24 covers higher-wattage lamps from 20W to 70W. Both share the same 24mm pin pitch but the lamp base body dimensions differ for higher-wattage GX24 lamps. Always verify the lamp datasheet before specifying the socket.
Are these sockets compatible with LED PLC retrofit lamps?
Yes, for 2-pin G24d/GX24d sockets with direct-fit LED PLC lamps. For 4-pin G24q/GX24q, LED retrofits typically require ballast bypass wiring. Confirm compatibility with your LED lamp supplier's datasheet before installation.
Do you supply pre-wired holders for OEM assembly?
Yes. Pre-wired holders with specified lead wire length, gauge, and termination are available for OEM luminaire production. Contact us for custom configurations and batch pricing.
What is the minimum order for bulk pricing?
Bulk pricing is available from 100 units per SKU. Contact us for tiered pricing on larger quantities and mixed-base pallet orders for luminaire manufacturers and electrical distributors.
