About (Pack of 2) F13T5/CW 13-Watt T5 Fluorescent Cool White 4100K Super Long Life
Overall Feedback:
80% positive
80% praised for its long lifespan, while 20% experienced early failure
I tried the shorter version of the bulb in my other light fixture and it worked. This makes me think it might be a quality control issue.
The first bulb did not work at all and the second one burned out after only 10 days of using sporadically.
79% appreciated the perfect size and fit, but 21% found it small
I am having trouble fitting the bulb in my light fixture as it seems a bit too long.
The new lightbulbs don't fit the existing ballast, even though the model number is the same.
