Justusfish, I realize this is a old thread. I am upgrading my ballast on my 150W Aqualight right now. I went with the Galaxy selectable e ballast. I'm thinking now if I should upgrade the lamps as well (seeing that all I have to do now with the ballast is flip the switch from 150 to 250).
I know the end caps are larger with the 250W bulb, are the 250W bulbs and longer as well? Or can I just replace the 150W endcaps with 250W endcaps?
