Frequently Asked Questions
What is the difference between GX24q-2 and GX24q-3 bases?
The GX24q-3 base (used on this 26W lamp) has a different pin configuration and keying than GX24q-2 (18W) or GX24q-4 (32W/42W). These are not interchangeable. GX24q-3 uses 4 pins in a specific layout that only fits 26W programmed start ballasts. Verify your socket marking or existing lamp base before ordering.
Can I replace a 26W CFL with an LED in the same fixture?
Yes, but with considerations. Option 1: Use a plug-and-play LED designed for GX24q-3 bases (works with existing ballast). Option 2: Use a ballast-bypass LED (requires rewiring to 120V direct). Option 2 offers better efficiency (12W vs 26W) but requires electrical work. Ensure the LED's lumen output (1,600-1,800 lm) matches your needs.
Why won't my CFL turn on or flickers?
Common causes: (1) Incompatible ballast - verify GX24q-3 programming (not 2-pin or other wattage). (2) End of life - darkening at tube ends indicates replacement needed. (3) Cold temperatures - standard CFLs struggle below 0°F; this Ecolux model performs better but may still delay in extreme cold. (4) Incorrect voltage - verify 120-277V ballast rating matches your supply.
Is 3500K too cool for office lighting?
No, 3500K Natural White is the "sweet spot" for commercial office lighting. It provides better visual acuity than warm white (2700K-3000K) without the clinical harshness of 4100K cool white. 3500K is the standard for corporate offices, retail, and task lighting where color accuracy and alertness are important.
Can I use this CFL with a standard wall dimmer?
Only if you have a dimmable ballast specifically designed for CFL dimming (such as Sylvania QTP2X26/CF/UNV DM) AND a compatible dimmer switch (typically 0-10V low voltage or specific CFL/LED phase dimmers). Standard incandescent dimmers will cause flickering and damage. If unsure, contact us to verify your ballast model.
