I do not understand the logic - sorry... This is not the sign of aggression, but
it does not make sense: you religiosly change VHOs every 6 months for what
reason? Does the same reason apply to overdriven NO tubes or not?
If so, why do you change them based on the look, while you change VHOs
even if they still look good? Overdriving NO does not make it VHO! :-)

I religiously change VHOs at 6 months because that is the life span of these bulbs. Now, who's
told me that? Tons of people. Is it true? Don't know, but why rock the boat yet again? If that
is the lifespan, so be it. Now if I've been misled and they are good for 8 or 9 months, well it's
too late now.


It states 6500K. That is the color spectrum of that bulb.

When overdriven?

Sure, why not? talk about opening a can of worms here As you know, I'm in it for the hobby not
the science. It *looked* good to me.

Yes, but some things can't be fudged. They can't say this bulb reduces algae or anything.
They state what color to expect. I think that would be a reasonably honest thing to do.

They do not state how this tube behaves when overdriven.

True, but the person that suggested this to me in the first place is someone I trust.

How much do you save now each year? :-)

Nothing. However, I can finally get an Table acropora. Yay!!
