2G7 2GX7 G23 GX23 LED PL Lamps
2G7, 2GX7, G23 and GX23 LED PL lamps
This is a mixed collection of horizontal plug-in LED replacement lamps. Selected products offer four-pin 2G7 or 2GX7 variants, while much of the current range consists of two-pin G23 and GX23 lamps. The collection contains lamps rather than standalone lamp holders, and the exact base available must be confirmed from each product’s selectable options.
Available product groups
- 2G7 LED lamps: four-pin horizontal lamps in selected 3W to 10W options, including products with lengths from approximately 120mm to 220mm.
- 2GX7 LED lamps: four-pin variants offered on selected mixed listings, with separate low- and high-voltage input options on one product.
- G23 and GX23 LED lamps: two-pin horizontal or side-view lamps in selected 3W, 4W, 5W, 6W and 7W options.
- Mixed-base listings: some products offer 2G7, 2GX7, G23 and GX23 choices on one page; other titles mention four-pin bases even though their current selectable variants contain only G23 or GX23.
- Color and package options: warm, natural and cool white choices, lamp lengths, voltage ranges and one- or two-piece packs vary by listing.
Pin count and base identity
Both 2G7 and 2GX7 products in this catalog are four-pin interfaces. G23 and GX23 are two-pin interfaces. They must not be treated as interchangeable because pin count, keying, contact arrangement and fixture circuitry differ. A similar PL-S body, shared wattage or apparent pin spacing does not establish compatibility.
How to choose a replacement lamp
- Read the complete base code: match 2G7, 2GX7, G23 or GX23 exactly and compare the physical keying of the old lamp and socket.
- Check the actual variant: use the selected option rather than the product title or image. Not every base named in a title is currently available as a variant.
- Identify the fixture circuit: determine whether the fixture contains a magnetic ballast, electronic ballast, direct mains connection or another driver.
- Follow the product installation requirement: several LED listings specify ballast removal or bypass. Do not assume a common wiring method across the collection.
- Match input voltage: some variants are separated into 85–135V and 195–265V ranges, while other products use different voltage wording. Choose the exact range for the installation.
- Verify dimensions and output: compare lamp length, horizontal orientation, wattage, color temperature and available fixture clearance.
- Confirm pack quantity: similar listings may sell one, two or four lamps.
Ballast and wiring safety
A physical fit does not prove electrical compatibility. Direct-wire LED lamps may require the existing ballast to be disconnected, while another replacement may be intended for specified control gear. There is no universal ballast-bypass wiring pattern. Follow the exact instructions for the lamp, ballast and luminaire, isolate power and use a qualified electrician for fixture rewiring.
Compatibility boundaries
Do not infer interchangeability from “PL,” “PL-S,” wattage-equivalent claims or lamp shape. Verify pin count, keying, socket geometry, supply voltage, ballast or direct-wire requirement, lamp length and orientation. Electrical ratings, materials, service life, color rendering and certifications are product-specific rather than common collection specifications.
Typical applications
These lamps may be suitable for clearly identified desk lamps, reading lights, ceiling fixtures, wall lights and other compact luminaires. Suitability depends on the selected base, fixture wiring and physical clearance, not the application name alone.
Frequently asked questions
Is 2G7 a two-pin base?
No. The 2G7 products and variants in this collection use four pins. Do not confuse the “2” in the base name with the pin count.
Can 2G7 and 2GX7 lamps be interchanged?
Not automatically. Both may have four pins, but keying and socket geometry can differ. Match the complete printed base code.
Can a G23 lamp replace a 2G7 lamp?
No. G23 is represented here as a two-pin interface, while 2G7 uses four pins and a different circuit arrangement.
Do all lamps require ballast removal?
No single rule covers every listing. Several products explicitly require removal or bypass, but the correct method depends on the exact lamp and installed control gear.
Why does a title mention 2G7 or 2GX7 when I cannot select it?
Some imported mixed-product titles describe a broader family than the current variants. Treat the selectable base option as the orderable configuration.
