I had the 175 W Blueline 14K lamp with a Mag 57 balllast I LOVED the look of this lamp

I just switched to the XM 20K and the tank is by far whiter and brighter
I may switch back
I keep softies so I think the blueline may be fine for me althow the par is major difrence from the Blueline to the XM
The test was on the 250W blueline and it was in the dumps BUT Looks great
