Lighting 180G (72x24x24)

[ALang]

OK. Thanks. It is pretty obvious now that you mentioned Dbl Ended as DE.
And I do agree that I will need to change them very soon. That's why I am seeking advice. But with all the bewildering arrayed brands of bulbs out there, can someone please suggest a few (readily available, pls) that I can try, in order to get that nice blueish color? Do I need to go higher than 10,000K ?? Right now I have the 10,000K ( thought they were 14,000K) Coralife brand bulb that came with the fixture. Don't ever remember the lights as being that blue, though.
