Additional Information

Approximate initial lumens measured after 100 hours. Performance depends on ballast type and temperature. Lamps may experience abnormal end-of-life behavior (e.g., cracking or overheating) when used with high-frequency ballasts. Use ballasts with integrated end-of-life shutdown protection.


Life ratings are based on 3-hour cycles. Longer cycles extend rated life. For comparable light output, divide incandescent wattage by 4. Optimum light output for Dulux T/E IN lamps occurs at ~95°F (35°C) in base-up position.
