Bulb sizing/length question

t0p_sh0tta · 09-26-2008, 03:29 AM

Quick question. I have a 30" Current USA fixture that runs 24w HO T5 bulbs. I ordered some 24" Giesemann bulbs tonight, but the bulbs in the fixture measure ~22".

Because of the wattage, I'm assuming that they're compatible, but I'd just like to make sure.

Thanks,

Lamar

The bulbs you ordered are correct. The 24 inch T5 HO is really 22 point something inches from pin end to end. Same with the 36 inch and 48 inch, meaning they are all a bit smaller then their actual listed lengths.

lol, I just realized how stupid this question was. How would a 24" bulb fit in a 24" fixture over a 24" wide tank...

lol
