What is the real measurement of my florence tube bulb ?!?!?!?

Question

Why is it that I measure my florence tube bulb and I get 22" but there is no place that sells 22"s and the maker of the fish take says it is an 18" light blub. I check the specs for the replacement part and everything and it keeps saying 18" but I measure 22, wtf?!!??!!??!?!

Answer 1

If the makers says it is an 18" then it probably is. You only measure to the end of the glass tube, the prongs and stuff don't count with the measurement of the bulb. Or take the bulb into the store with you and they will know exactly the size you will need.
