G23 GX23 LED PL Lamps & Socket Adapters
G23 and GX23 LED PL lamps, holders and socket adapters
This collection is primarily a replacement-lighting range for horizontal plug-in PL lamps. It includes G23 and GX23 LED lamp options, selected 2G7 and 2GX7 variants, a G23 lamp holder, and base adapters that connect specific pin-base sockets to E26 or E27 screw-lamp interfaces. Product format, base, voltage, wattage, length, light color and pack quantity vary by listing.
What is included
- G23 and GX23 LED PL lamps: horizontal and side-view replacement lamps offered in selected 3W, 4W, 5W, 6W and 7W options, with individual listings covering different lengths, input voltages and color temperatures.
- 2G7 and 2GX7 options: some mixed listings also provide four-pin base variants. These must be selected by their exact option and are not interchangeable with two-pin G23 or GX23 bases.
- G23 lamp holder: a limited holder listing for a two-pin G23 lamp interface.
- Socket adapters: selected G23-to-E26/E27 and GX23-to-E26/E27 adapters, plus mixed listings containing G24D, GX24Q, GU24 and unrelated lamp-base options.
- Mixed or outlying products: the collection also contains G24/E27 LED lamp options and adapters whose selected variants are not G23 or GX23. Read the option name before ordering.
G23, GX23, 2G7 and 2GX7 are different interfaces
Do not select a lamp from the shared “PL” appearance alone. G23 and GX23 products in this collection use two-pin configurations, while 2G7 and 2GX7 variants use four pins. Keying, center blocks, tabs, pin arrangement and seating geometry can differ even when the lamps have a similar horizontal body. A shared wattage or similar external size does not prove mechanical or electrical compatibility.
How to select the correct replacement
- Read the base code on the old lamp and socket: match G23, GX23, 2G7 or 2GX7 exactly, including pin count and keyed features.
- Identify the existing control gear: determine whether the fixture uses a magnetic ballast, electronic ballast, direct mains input or another driver arrangement.
- Follow the product-level wiring requirement: several LED products are described as ballast-bypass replacements, but this cannot be assumed for every lamp. Other LED replacements may be designed for particular ballast types.
- Match electrical specifications: select the exact input voltage, wattage and lamp configuration shown for the variant. A 110V option and a 220V option are not substitutes.
- Check physical clearance: compare total lamp length, horizontal orientation, rotatable features and fixture space.
- Choose light output options: color-temperature choices and pack quantities differ by product and variant.
Ballast and retrofit safety
A pin-base-to-E26/E27 adapter changes the physical contact format; it does not convert voltage, frequency, ballast output or lamp electronics. Some listings require the existing ballast to be removed or bypassed. There is no universal bypass wiring pattern because ballast and luminaire circuits vary. Follow the exact instructions for the fixture, ballast and replacement lamp, isolate power, and use a qualified electrician for rewiring.
Compatibility boundaries
G23 and GX23 should not be treated as interchangeable merely because both are described as two-pin PL bases. Likewise, G24D, G24Q, GX24Q and GU24 options belong to different keyed families. Confirm pin count, keying, contact position, operating supply, ballast requirement and lamp dimensions. The collection does not establish a common voltage, current rating, material, temperature rating or certification for every product.
Typical uses
Products in this collection are intended for clearly identified desk lamps, reading lights, ceiling fixtures and maintenance projects that originally use the specified PL base. Suitability depends on the fixture circuit, available space and the exact selected variant rather than the application name alone.
Frequently asked questions
Are G23 and GX23 lamps interchangeable?
Not automatically. Both may be two-pin formats, but their keying and socket geometry can differ. Match the printed base code and physical interface.
Can a four-pin 2G7 lamp replace a two-pin G23 lamp?
No. The pin count and electrical interface differ. Choose the exact base required by the fixture.
Do all LED PL lamps require ballast removal?
No single rule applies to every product. Some listed lamps explicitly require ballast bypass, while compatibility for others depends on their design and the installed control gear.
Does a G23-to-E27 adapter make any E27 bulb compatible?
No. The adapter does not change the electrical supply or fixture rating. The new lamp must match the rewired or existing circuit, available clearance and thermal limits.
What should I verify before ordering?
Confirm the exact base code, pin count, keying, input voltage, ballast or direct-wire requirement, lamp length, orientation, wattage, color temperature and package quantity on the product page.
