Startup Notes: Mean lumens are measured at 40% of lamp life. Initial lumens measured after 100 hours. Starting temperature depends on ballast—consult ballast manufacturer.

Ballast Compatibility: Use with magnetic rapid start ballasts (265 mA) or compatible high-frequency electronic ballasts (instant, rapid, or programmed rapid start). For instant start mode, ensure socket terminals are properly wired and connected per NEC standards.

Lamp Life: Rated on 3-hour operating cycles. Longer cycles can significantly increase lamp life. Use only with ANSI-compliant ballasts for rated performance.

SUPERSAVER® Use Guidelines: Only use with F32T8 ballasts with ≥550V RMS open circuit voltage. Do not use with:

• Remote ballasts below 550V
• Air handling fixtures
• Low power factor ballasts
• Emergency lighting systems unless approved

Incompatible applications may cause startup issues or premature failure.

Cold Environment Warning: Below 60°F (70°F for 25W), lamps may show striations or dimming. These effects are harmless and usually resolve once the environment warms or drafts are eliminated.
