I agree, my T5's come right on. I have had touble in the past with bad T5 bulbs, I would suggest calling and getting a new set of bulbs, or at least checking all of your connections.

I agree they may not be seated properly.
Put sunglasses on and start them up see if they do it but don't wait too long to return them

Mine come on right away.

curious what kind of bulbs. i have ati. bulbs 2 blue plus 1 12k aquablue special 1uvl 75/25 14 k aquablue i noticed that when i first turned my lights on the 14k took a minute or so to come up to par the same way you described it my lights are brand new as well but now it seems to come up to par much faster. i dont think its a problem with the bulbs it just takes a minute or so to reach full par.

Once you replace the bulbs with better quality bulbs you will see a difference in your tank... I used the stock current bulbs and replaced them with giesemann bulbs...big difference in coral and color

Huge Diff!!!!

Just checked with reefgeek about their ATI bulbs, it is normal for their bulbs to take a few min to worm up before its at 100%
