Review on 💡 Sylvania 20667 Compact Fluorescent 4 Pin Double Tube, 13-watt, 4100K by Karen Mabey

These compact fluorescent bulbs are becoming increasingly difficult to find and I was very happy to find the 4100 degrees I wanted. The lamps match my lamp and I am fully satisfied with it. I did not find the advertised dimensions of the product helpful as it would be too long for my fixture if the advertised length was the actual length of the bulb. For the information of other potential buyers, the overall length of the bulb is 5 and 1/16 inches - if it were any longer it wouldn't fit in my fixture. dissatisfied). Previously purchased products clearly do not live up to the promised long life of fluorescent lamps. In fact, it's not at all clear if they will survive incandescent bulbs.
