2-Pin Plug (Magnetic)
2-pin plug-in CFLs are designed for fixtures with magnetic (electromagnetic) ballasts. The 2-pin base configuration includes an integrated starter, making these lamps a simple, direct replacement — just match the pin base and wattage to your existing fixture.
Brand Cross-Reference Guide
Each major manufacturer uses a different product line name for the same lamp type, which can make finding the right replacement confusing. Here is how the naming conventions align:
- Single Tube (G23 base): Philips PL-S | GE Biax S | Sylvania Dulux S
- Double Tube (G24d base): Philips PL-C | GE Biax D | Sylvania Dulux D
- Triple Tube: Philips PL-T | GE Biax T | Sylvania Dulux T
- Long Twin (2G11 2-pin base): Philips PL-L (2-pin) | GE Biax L (2-pin)
All of these lamps are cross-compatible across brands as long as the pin base type and wattage match. For example, a Philips PL-C 26W/835 with a G24d-3 base can be replaced by a GE Biax D 26W/835 G24d-3 or a Sylvania Dulux D 26W/835 G24d-3.
These lamps are commonly found in downlights, wall sconces, and commercial task fixtures across offices and hospitality environments.
