Good Bulbs?

Because of the raised center bar on my 55g, I am basically stuck with the two 18" single strip hoods my tank came with. I want to replace the stock lights that came with it, and I'm just basically looking for lights that are going to bring out my fishes color - I don't have any live plants and I don't want to encourage algea growth. Good choice?

Those sound really good. But you won't know for sure until you buy them.

For lights ... anything with a temp of 10,000K and actinics are the best for bringing out natural fish colorations.

I tried a 50/50 bulb and it was really dull, I think with a single strip light I'm better off with just a really bright normal spectrum bulb, no?

i didn't say to use a 50/50 because as you stated ... a 50/50 does make it a bit duller ... use one bulb that is 10,000K and the other is actinic. That way, it gives the best natural and bright light possible. anything over 10,000K gives a more white light.

Those bulbs won't be too dim, but it's really hard to say since they don't provide a K temp or a CRI chart for them.

I had a bulb for a while that was an 18,000K color temp. The higher you go over 10,000 the bluer the light gets. This isn't to say 18,000K is anything like actinic...just that if you held it side by side to a 10,000, it'd have a noticably blue tint to it.

That will really bring out the red, blue and purples in your fish. yellow will be largely unaffected, as are greens.

You might hit your LFS and see if they have these in stock, as i'm sure the package itself has at least a K value, if not a spectral graph.
