led aquarium lights

I have had my Hydra TwentySix HD LED's running about 4 months and i was wondering where do you kept your setting at on your Hydra lights! Also, how long do you run them when they are fully rampped up.. Let me know! I run these setting below for 7hrs w/ a 1 hr ramp up and a 1hr ramp down...

90cm (L)*55cm(W)*50cm(H) tank in our office, powered by 150w Pixie 150. :( my new Canon 750D didn't show the colorful effect.
