175w SE Hamilton 10k to 175w SE Iwasaki 14k

First of all, I want to update on my green bulb color. After a lot of research into the nipple orientation thing, I read a few testaments to the fact that it depends on the bulb.

We turned the nipples and our Hamilton lights immediately changed color to white.

I had ordered, and now received, my Iwasakis and just put them in tonite. They are exactly the same color, a nice white, at the moment. I will keep the Iwasakis for the better par, but was quite astounded at the difference the nipple orientation made.

And all those articles that say it doesn't matter ... weird. I don't know if it's more superstition on my part or what, but I always try to get those things pointing upwards and will adjust the socket if I have to... Glad to know it's not a completely superfluous thing to do that.

I have tried to always keep them orientated correct but have never seen a difference myself. Thats an interesting observation Deb.

Look forward to your views on the new Iwasaki,s. I,m still sticking with my SA or CV, 14K bulbs for now. Does the Ushio 10K not offer a white/blue light and good bulb life? I always thought it was the best 175 I have seen but I prefer the more blue content and bulb price of the cheaper 14K,s.

I have followed most of the Iwasaki 14K threads over at RC though.

I should have taken some photos. If I am really nice to hubby, maybe one day we can stick them back in to do that. He hates taking fixtures down...

Apparently the Ushio would not have good color on my standard M57 ballast.

The iwasaki's have gone just a bit more blue, which is wonderful ! The coral colors appear nicer. I think I will like them very much !

Excellent! It's by far my most favourite bulb too. I just keep hoping we'll see more of them. Gotta get the word out about them so that people will want them .. if there's anything to the "supply/demand" economics thing..

I must be really dumb because I don't have a clue what you guys are talking about.

I know the 250w Ushio 10K are quite yellow, and need some serious actinic supplementation to even get to white, let alone bluish. They do have good life though, and the color doesn't change much in 12 months.
