Old bulbs = Algae problems?

[Son Of Skyline]

Thanks for the quick replies everyone. I know that lighting isn't the only thing contributing to my algae, but I'm just attacking all possibilities. I just bought a nice big RO unit, foxface, lawnmower blenny, dropped my lighting down to 7 hours a day, cranked up my skimmer, doing more water changes, pulling it manually, brought my alk up to 4.5meq/L. The only thing left I can think of is replacing my old bulbs. I don't want to give this algae a chance to win! Am I missing anything?

The tank is a 120gal with a 27gal sump.
Canreef skimmer on a Mag18.

Tank's been setup for less than a year so I'm not surprised about the algae outbreaks, but I still want to attack it as hard as I can.

Thanks all.
