## Description

21 Inch T5 Fluorescent Light Bulb 13 Watt F13T5/WW for Sylvania Satco Philips GE Under Cabinet Tube Light 21 inch Warm White 800 Lumen G5 Base 8 Pack

Review: These are perfect to fit my under counter light fixtures. I went to all the local stores. No one had this specific length or slim profile. What they did have that was similar ranged from $11.89 to $24 - for one bulb! So this was a good deal for 8. I have 4 light fixtures, since this was the first time a bulb burned out I figured it’s a matter of time til they all do. Well packaged. Bulbs wrapped individually and snug in manufacturer’s box, then in a larger desertcart box. Photo shows old bulb in front.
Review: Works as expected.
