    UV L has both bulbs available in VHO, but I can not seem to find a pros or cons on either spectrum anywhere.

    Anyone know what the difference is? Is one better?

    I just replaced my power compacts last week. I had original coralife actinic bulbs, and i replaced with Aquatic Life 420/460nm bulbs. 420 are more darker more purple bulb. 460 are brighter and more blue bulbs. Take your pick as to what look your going for. Personally, the mixed bulb is definitely brighter but I think next bulb change im gonna stick with full 420. Hope that helps
