2 pin PL LED Bulb, 4W, 450lm, 3500K, Omnidirectional, Replaces 13W CFL, G23 Base, Ballast Bypass

You must match the pin count exactly to your existing fixture. 2-pin PL lamps (like G23, GX23, and G24d) are typically used with a magnetic ballast. 4-pin PL lamps (like 2G11, 2G7, and G24q) are generally used with an electronic ballast or are wired to bypass the ballast entirely. Always check your existing bulb's base for the correct code (e.g., G24q-3).

It depends on the bulb type you purchase. Some LED PL lamps are ballast-compatible (often called "plug-and-play"), meaning they work directly with your existing ballast for the easiest installation. Other lamps are ballast-bypass (or "ballast-free"), meaning you must remove or bypass the existing ballast before installation. Check the product specifications for the required wiring method.

LED PL lamps consume significantly less power to produce the same light output. A typical 26W CFL can be replaced by an LED bulb between 10W and 13W. Always check the LED bulb's lumen output (lm) to ensure it matches or exceeds the brightness of your old fluorescent bulb, regardless of the wattage difference.

The main difference is the pin configuration, which affects ballast type. A G24d base has 2 pins and is generally non-shunted (used with magnetic ballasts). A G24q base has 4 pins and is typically used with electronic ballasts. Confusing these two will result in incompatibility.

LED PL lamps offer massive energy savings, typically up to 70% less power consumption than CFLs. They also last much longer—often 5 to 10 times as long—which significantly reduces maintenance costs and the hassle of frequent bulb changes, especially in hard-to-reach fixtures.
