well the aquaconnects are supposed to be identical to the phoenixes aren't they?

I've heard good things about the Phoenix 14k's and the Ushio 10k's. I haven't tried either of them but my tank is due for a bulb change too so I'll have to pick something up soon.

I took a chance with the Ushio's 14K (DE tho) as my first MH bulbs and I have really liked them.. White with very slight blue hue.

The corals I had in my 20G (that were under 175W 13K Aquamedic SE) seem to have responded positively since transferring them to my 75 under the 250W 14K Ushio's.

Well ,today I went to J&L and picked up the 13K Giesemann Megachrome 400W SE and I have to say after having them on for about 2 hours, I sure like them, just the right mix of white and blue, and man they are BRIGHT!

What kind of ballast? I have been debating those exact ones.

HQI ( high output ? ) ballast

You're running 400w SE's on an HQI ballast? No wonder they are bright!!! The HQI actually overdrives the SE as HQI are deisgned to run DEs. The Giesemanns are often nice bulbs. I realy like the 250w 13,000K SEs, but they are an expensive bulb, and the Ushio and XM have higher PAR (if I remember correctly...I haven't been up on lighting lately).

Hummm Interesting. That a possibility. Haven't tried those and I sure like the DE ones on Tom R's tank

Ya, I had the 250W DE HQI's on my last tank, and I needed new bulbs so I figured why not try them now with 400W SE.
And I am very impressed to say the least, I would say they are very simlar to the DE ones
