These lamps are designed to be used in more compact, decorative fixtures where a standard Compact fluorescent lamp won't fit. With efficacies and color properties similar to standard fluorescent lamps, their rated lives are comparable to Compact fluorescent lamps at approximately 12,000 hours. 6 inch 8 inch 12 inch 16 inch T5
