I bought a new bulb
 

And Ms. "I hate yellow" likes it !! :cool:

As you know, I'm limited on bulb selection because I have CHEAP ballasts.... :lol:

Anyway, if this one burns in as good as it looks right now, I'm in for the two more. Then I think I'll pull out the 4 x 55w pc's, run the MH parallel and shoot in some actinic for polish.

The spectral analysis is interesting in comparison to the Iwasaki, which didn't work at all for me.......not that I understand it, but comments please ! :mrgreen:

Looks good to me.
Where did you get them from and what kinda color do they put out(visually)?

Bumper Crop - it is burning very much bright white. Maybe a tinge of yellow, but you know me. :razz:

I've been trying to get a decent pic, but it keeps showing up the green algae on my back glass...doh...I'll work on that tomorrow :lol:

Cool! How much were they and what wattage did you pick up?

$100 for the 250W. He was very nice to let me try a couple bulbs and take them back with no restocking charge. This one I think is a keeper, but...now I need to reach the back of the tank....

Did you also try one of the "Aquarium Deluxe" bulbs?

Wait, of course you did...

:redface:

Nope. Didn't need to yet. :lol:

It was the next try tho... :razz:

Man....I can't believe how things are reacting..
:eek:

Less yellow than the Iwasaki? Lets see some pictures :wink:

Yes Deb, lets see some pics :biggrin:
Not like your reef looks great already :wink:

And this one here just for a funny: :biggrin:

Yikes! Your camera make that one, or is it one of the "trial" bulbs??

In the first photo, then new bulb is over the center of the tank?

:lol: That is EXACTLY how Ushio bulbs looked over my tank. That pic was Nov 2001. I think it took Barry 3.4 seconds to run over to the tank and pull the bulbs out to return them..... :eek: I don't remember if I took pics of the Iwasakis :question:, but they weren't a whole lot better. Maybe he gave it five minutes or so, since I had kept saying what good bulbs they were...... :rolleyes: :biggrin:

Yes, when the snow plows come...... :lol: I will go get a couple more. At least my anemones are happy :cool:

That's a very nice color for the center bulb. Do you have the actinics on at that point?

No, the small pc's never did much anyway on such a large area, so Barry has disconnected them and is pulling them out.

Years ago when I switched from 14k's to 10k's over my 50 I found the anemones were the first to indicate their approval of the new lighting. They pretty much immediately expanded about double. They seem to be a pretty good indicator of lighting.

Interestingly enough, I find nowadays my BTA's look kinda ugly, and not really inclined to expand much. In fact, I think they're smaller than when they were under NO lights. I'm not sure if it's a function of them not being happy with the Iwasaki's (they have never looked "great" ever since I moved them into my Iwasaki-lit tank), or if it's because maybe my tank has overcrowding issues and there's just too much going on chemically (allelopathic inhibition?? who knows...).

I have been thinking about adding a third bulb to my 75g once I switch over to Radiums. Was thinking, do I want it to be Iwasaki? Or something else? The reason I'm hesitant to remain with Iwasaki's is that I would want to find a "non-M57 H37 ballast" to run it on, so I thought, why not just use an Ushio 10K since the M59 is the "correct" ballast for that bulb (according to the Ushio website ... which I found to be surprising since the 175W and the 400W versions are intended to be used on the pulse-start ballasts instead). Reading your comments regarding the Ushio reminded me of the issues of yellowness you had with those bulbs. Hmmm. Now, I'm still rather confused what I want that third bulb to be (I just want something to balance things out at midday for a few hours). Invest the $100 in a H37 ballast and see for myself if the Iwasaki's really do look whiter/bluer, or just say to heck with it all and forget about it.

The bulb that interests me most in the 10k/mogul range are the ones that Steve uses on M80's. But that means new bulb new ballast == mucho deniro. Ay, carumba.
