The question is I have a couple of ballasts and lights which I think are HO. How can I tell?
Here is the number off the lights
F72T12/D/HO 85 WATTS ALTO COLLECTION BY PHILIPS.The bulbs are 6' long.
Thanks in advance for the help.

In that part # the HO at the end stands for High output

So what you have are HO's
