Help with T5 bulb selection

Usually that POP in colour comes from a very blue light like an Actinic bulb or a 22K bulb.

Hi there

Right now am using 2 Current Actinic and 2 Giesemann Pure Actinic. I like how my corals look under these bulbs but I wonder if there is anything better than what I currently use.

Oh, and one more question...these bulbs have been there for over 2 years. How often are these T5 bulbs suppose to be changed? There is nothing wrong with the corals or tank in general. Everything is thriving and looks healthy so I wonder if I should really change the bulbs or stick with what I have.

Thanks
