Buying notes and support

Important: this is a true 12 inch T5 tube, not 9 inches or 22 inches — measure before purchasing to ensure a proper fit. If the ballast inside your fixture is defective, the bulb may not light. Our 24/7 support team is available to help troubleshoot and discuss refund options if needed.
