Before You Order

• Verify Diameter: This is a T12 lamp (1.5" diameter). While it uses the same G13 base as T8 lamps, ensure your fixture and ballast are compatible with the larger T12 bulb profile and wattage requirements.
• Ballast Check: Must be used with a certified 20W T12 fluorescent ballast. Performance may vary significantly with magnetic vs. electronic ballasts.
• Color Tone: 6500K is a very cool light. If you prefer a softer, yellowish tone for residential living areas, consider a 2700K or 3000K alternative.
• Environmental Note: While ALTO technology reduces mercury, these lamps still contain trace amounts and should be recycled according to local regulations.
