UVL t5 Bulb question

[blades326]

can someone please explainthis for me. I am looking at buying new bulbs for my NEP and I am looking at getting 8 ATI blue +, 2 Geissmann mid days, and 2 UVL actinic whites. My question is this... The ATI and Giessmann both say 36" bulbs which is what my fixture uses but the UVL bulbs are listed as 34" bulbs. Will these (UVL) fit in my fixture? I am a little confused please help.

Yes they are all the same length which is 34 and change from memory. Many sites and people refer to T5s them as 24, 36", 48 because they are numbers people are used to.
