175???, how are they in 250?

Tony, the last I read was nipple sideways. I'll try to find that, but it worked in this case.

Interesting, thanks Tony. Am I to assume that is just the mogal base bulbs that have these nipples?

Do you mean the Iwasaki's? The 14K's only come in 175W at the moment. There is talk on RC about eventually there being other wattages but so far I haven't seen them offered anywhere.

But seriously, the 175W 14K Iwasaki lamp kicks some serious butt. It has higher PAR and lumens than some 250W lamps.

Now that I have a bit more time I was able to search up Sanjay Joshi's review on the lamp:

(Search on "Iwasaki 175W Aqua2 14000K Mogul Base")

Hi Greg,

I think, as an artifact of the manufacturing process, all arc tubes have the nipples (it's where the inject the gases? I think?), it's just that DE's don't give you an option.

Marie, my friend has been on the same quest since selling his vho,s several years ago. After running 14K 400w bulbs for a year, he went to all T-5,s. Just recently he chucked his T-5,s completely. Figures his tank has never looked good since the switch from halides and its all soft corals & huge leathers.

He just put a pair of SA, 14K, 400,s back on. Likes the look but still not the same as the vho look. He is thinking of adding a pair of vho actinics. From our running of T-5 actinics, just not the same as the vho actinics.

I just dont thing the same colour can be reproduced by anything else. I would think, {not using} , that the Iwasaki 14K would be a similar light to the Ushio 10K. My SA 14K,s {175w}, have a nice bluer look but not the same as vho nor my T-5,s.

Yes, I am running VHO's with it, so that helps with the colors as well.

Deb,

Where did you get your Isawaki's from ?

So, :smile: , either of you still running the 175 Iwasaki bulbs?
