Deb,

Where did you get your Isawaki's from ?

From Premium Aquatics Brent.

So,

, either of you still running the 175 Iwasaki bulbs?

Yep.

I don't wanna count the # of months on it now. Still going strong though, and I'll probably replace it with another.

I see Iwasaki has a 14k DE now in the 250W size. I might try that for my ritteri tank (250W DE over that one). Currently using a Ushio 14k on that one.

Yep, but I just brought the fixture back out to restart my in-wall tank. I was going to sell it...

You guys think they are as bright as the higher "K", [14& up], single ended 250 bulbs?

Unfortunately I don't really have any way to objectively quantify that. To the naked eye it's a bright, crisp-white colour. It is one of the nicest "white" lamps I've ever used. For brightness, I'd say it's easily comparable to an Ushio on a proper ballast - but unlike an Ushio, it is a probe start lamp, so runs, and starts, perfectly on my M57 ballasts.

Actually, the answer is a quantifiable "yes" when they are run on an electronic ballast according to Sanjay's results.
