I don't have halides and my 8x40w NO's have worked just fine now for 11 yrs of keep anemones.
My sebae is at the bottom of a 90g tank, and the most recent addition, a rose bubble tip, hides from the lighting on a 65 which also has 8x30w NO's with 4 of those lamps overdriven by an IceCap 660. The rose kept hiding and I kept exposing it to light until I gave up and it remains in a pocket in the rocks, sticking itself out I presume to capture food and perhaps a limited amount of light. I have since read quite a few posts regarding bubble tips hiding when placed in halide or other high light tanks.
As for the sebae, my first one was lost to my cooked tanks (96F) when the A/C quit 1 1/2 yrs ago while I was on holidays. It was the hardest thing to lose of all the corals and fish lost at the same time because it was the very first inhabitant I bought for my first tank, 11 yrs ago this month.
The replacement sebae has been doing just fine since then, so it wasn't just a fluke with the first anemone.
