Always run my led 10am-10pm with sunrise and set . Just got a hybrid t5 should I have my t5 kick on at 11 and go off at 9 ? Or should I run it for a shorter period?
Lighting schedule for t5 hybrid

If the PAR levels are similar I'd leave them.

Can you explain? I have a t5 hybrid led and t5 together with t5 on its a lot more par than just my 2 ai primes by themselves
I would use PAR levels to decide how much to change lighting schedule when changing light fixtures. If the PAR for new and old fixtures are close 10% -15% I'd leave the light schedule the same. If the newer fisxture is significantly brighter then I'd start with a much shorter schedule and adjust it longer over several months depending on how the corals are acclimating.

If you don't have a par meter i would just start slow. If it was me doing it without a par meter I would do it one of 2 ways:
1) leave the LEDs as is and have the t5s come on and run 1/2 hour during peak hours everyday adjusting this up a 1/2 hour every week until i got them where i wanted them (you can do this faster if you want but i try not to rush anything in reefing)
2) Turn the LEDs down 1/2 the intensity they are at now and run the t5s for the full peak hours and run a acclimation on the leds for a couple months time to bring them back up to where they are at now.
Obviously observing the corals during all of this and adjusting slower or faster as well.

I’m not really worried about acclimating just wondering about a schedule really

Ahh, if they are the non dimmable ones i would run them during the entire led peak hours
