I have a Sylvania Cool White F13T5/CW light bulb. I measured it 20 1/2 inches. But this T5 13W 4100K is 21 inches. Are they different?

This bulb will work. The measurement including the prongs is 20 1/2" and just 20" without. Not sure why they say 21".

Rated 1.0 out of 5.0 by Replacement bulbs for HD fixtures HD does not seem to carry the proper replacement bulbs for their fixtures for very long.
