If an ENERGY STAR qualified CFL fails before the end of the warranty, contact the manufacturer to inquire about a refund or replacement.
Save important information: receipts to document the date of purchase; the manufacturer’s contact information, such as the mailing address, phone number, or Web site address; and most importantly, the CFL model number.
If you no longer have this information, look at the CFL base to find the manufacturer’s name. Then contact information to inquire about a refund or replacement.
If all else fails, send information on early failures to
cfl@energystar.gov. Include the manufacturer’s name, the product model number, and a description of where and how the bulb was used. ENERGY STAR representatives can help you locate the manufacturer’s contact information
