The fans are working great , and making about a 10 degree difference around the HO t-5 light fixture. They easily attached the the shelves upright supports. i just used some zip ties through the holes already in the fans corners. they move fairly freely up and down and are firmly attached ,thanks to the zip ties

this one is lowered a little and is doubling as a circulation fan for the LL terr. by slightly opening the sliding door.

The power supply was wired. each connection individually ,
and then all together for safety and appearance.

This is the 2 bulb HO t-5 i put up , when i took out the 4 bulb. didnt wan't to cook my plants or my house, I'm now sure with a couple more fans set up just like these on the other end , i can put my 4 bulb HO t-5 back up and get all the air movement i need, to prevent the heating issues i was concerned about.
Ill be using Av8tors suggestion of having separate power supplies for the fans
, only two to three per supply, so if one stops the other will still be going, again for safety purposes .
