175w Iwasaki Output > 250w MH?

Maeda · 04/29/2006, 03:07 PM

175w SE 14000k Iwasaki = 86 ppfd (bottom of the page)
Reviewed Here

VS.

50-80 ppfd from all the 250w bulbs I wanted to use.
Reviewed Here

Can this be right?
MORE light output the 250w 14000-20000k bulbs?
No drawbacks + savings in energy costs???

Am I dreaming or is this the perfect lighting solution for me?
For a 24x24x12inch tank...

I guess the only draw back is that I need to use this bulb and this bulb only...

Apparently my xenias love this new light. Under the 20000K, some of the xenias I fragged were just starting to heal, and after adding the Iwasaki, not only have they healed, but I see new polyps already in record time! Using this bulb has pushed me to want to turn on my Actinics, but with the growth I'm getting, it's well worth it.

Yeah its right... I cant wait till they come out with the 250w version later this year, hopefully it'll put out close to what 400w bulbs do!

I have this bulb in use and like it a lot. I have a ReefOptix pendant for it: very nice, IMO.

Iwasaki must WANT me to start my new tank sooner.

Thanks for the replys!

That doesn't compare the par output of a 250 Iwasaki overdriven. In a previous article it said that combination puts out the most par (250 Iwasaki SE with an HQI ballast). I think you can use any bulb with those ballasts (SE and DE) if you get sick of Iwasakis but when they're overdriven they come out white like 10Ks.

XeniaMania · 04/29/2006, 07:16 PM

hmm...is that why mine is not so blue? Interesting...maybe it'll be more blue next week w/ the eballast..

Oh sorry. I was talking about overdriving Iwasakis (6500K) on an HQI ballast. I didn't know Iwasaki made anything other than 6500s until now.
