Why do you want actinic lights? They are meant for reef tanks, and aren't
generally recommended for freshwater plants. Some people even think they cause
algae.

You'd probably be better off posting this question to to a marine or reef
newsgroup. They're the ones who have experience with actinics.

Better for what?

The Coralife seems to be a "true" 03 Actinic. The Hagen is a high
spectrum lamp, but it is not Actinic. '03 Actinic' is a specific brand
by Phillips, that has come to mean a tube that produces a high
spectrum light that is almost beyond the visible range. Actinic is
used by reef keepers to compenstate for yellower lights and make a
reef tank more pleaseing to the eye. Actinic is also used to make
corals floresce.

Also the Hagen uses T-10 size tubes which is fine if that is what you
need, but T-12 is more common.


Here is another source of Actinics

The "Super Actinic R" have an internal reflector.

it gives the tank a more pleasing look, 40 of my 120W are actinic, even
with
all powerglo's the tank looks yellow, now its very pleasing, I also have
the
actinics and not the powerglo's turn on in the morning and evening for
sunrise/sunset

I have an actinic on my freshwater tank, and it offsets the warmth of the
other two tubes. Introduces some nice blues into the mix. I don't have an
algae problem now the tank has settled down - the plants have found a
happier growth rate, I add co2 but not on a daily basis, and fertilize every
few weeks with a slow-release liquid. Plants are in gravel, no fancy
substrate. Heavily stocked with fish, and a decent external cannister
filter.

Initially I saw problems with BGA, some green hair algae, and a crop of
black brush stuff. After a few months, I stopped getting the BGA (lights
off for a couple of days every weekend used to keep it in check), the hair
algae went of it's own accord, and the black brush stuff has all but
vanished now too.

I do very infrequent water changes (in fact, I think the last one was over 2
months ago, possibly longer) - all the fish are healthy, happy, no diseases
in the time the tank's been set up (6 months to a yearish? can't remember
exactly).

So, I'm guessing the plants in there have enough light, but the algae
doesn't get enough to grow - regardless of the actinic in there - and that
the algae in there was either caused by excessive light initially (the tubes
are well due for replacement by now, I'm sure) or by the tank settling down
over several months, and/or the plant food I was using at the time. Running
it more as a self-contained ecosystem, bar the filtration, definately seems
to be working better at the moment - and I don't plan on another water
change for at least another couple of months.

The lights are all on at the same time, and off at the same time, so the
actinic is never there on it's own.

I like the actinic because even in a freshwater tank it makes my cichlids
look REALLY bright...almost as if their dorsal fins are florescing sometimes

So you just like the blue color. In that case, get whatever's cheapest.

Pay close attn to shipping prices on bulbs.
I've seen a few places charge up to $15 per bulb. I found the best price at
the LFS.
