Tips

To ensure a safe, correct, and long-lasting installation of your T9 Fluorescent Circline G10q 4000K tube, please review the following critical expert recommendations.

• CRITICAL: Requires Ballast and Starter: These are traditional fluorescent tubes and WILL NOT work without the correct control gear. They must be installed in a fluorescent fitting that contains a compatible magnetic ballast and a starter. They are not compatible with modern LED drivers.
• CRITICAL: Match Wattage to Ballast: It is absolutely essential that the wattage of the tube (e.g., 32W) perfectly matches the wattage rating of the ballast in the light fitting. Using a mismatched tube and ballast will lead to flickering, poor performance, and rapid failure of both the tube and the ballast.
• CRITICAL: Match Diameter and Base: Before purchasing, you must confirm that your fixture requires a T9 circline tube with a G10q 4-pin base and that the outer diameter (210mm, 295mm, or 395mm) matches your old tube.
• Replace the Starter: For optimal performance and to maximize the lifespan of your new tube, it is highly recommended to replace the fluorescent starter at the same time you replace the tube. Starters are inexpensive and a worn starter can cause a new tube to fail prematurely.
• Diagnosing Failure: If a tube is flickering, slow to start, or has blackened ends, the issue could be the tube, the starter, or the ballast. Always start by replacing the starter and tube together. If the problem persists, the ballast may need to be replaced by a qualified electrician.
• Safe Handling and Disposal: Fluorescent tubes contain a small amount of mercury. Handle them with care to avoid breakage. When a tube reaches the end of its life, it must be disposed of as hazardous waste according to your local municipal regulations, not in general trash.
