Hi guys
Can anyone give me the exact measurements of ati T5 24W bulbs?
I want to supplement a diy led canopy, and looking at their website it says 22.2” but I’m not sure if it’s the actual number. Because I have a 24w Phillips that I’m using for succulents and it measure 20.25” (not including the pins) and I was under the impression this is a universal size.
Appreciate any help! I don’t want to build it and realize the bulbs don’t fit

thank you
 
Including pins: 22.25"
Excluding pins and including metal caps: 21.625"
Glass tube only: 20.75"

You sure that Phillips is a T5HO bulb and not something else like T8?
 
thank you!
looks like i wont be about to fit those with the waterproof T5 end caps :/
i had another look and turns out the bulbs i have are actually regular 13W T5s that measures almost like the T5HO

Two are usually socket (not ballast) interchangeable.
Different brands seem to have some variability in size.
At least as I understand it.
Number after the T is just tube diameter inches in eighths.. t5 5/8" t8 8/8" or 1"
ho,no,vho just the wattage to run them at.
 
I've run ATI, UVL, Geissemann, KZ, GE and probably other bulbs.

I've run SS Tek, Coralife, Catalina, and Agrobrite fixtures. I've never had a bulb not fit.
