Iwasaki 250W and 400W "Blue" bulbs

[reptilicus]

G'day,
I was recently speaking to some people from EYE lighting (aka Iwasaki) and they mentioned that they now make a "blue" and a "green" 250W and 400W bulb. While I don't know if the "green" would be any real use, I'm sure this 400W "blue" bulb, which costs the same as a normal 6500K Iwasaki lamp, could be extremely beneficial to the aquarium hobby.
Naturally, I asked the bloke who works at the Iwasaki factory in Sydney whether he had the spectral analysis or any similar data at all, he said no. So I went to the Australian head office and head engineer in Brisbane, no. So we went to the head Iwasaki office in Japan. No spectral data has ever been done in this lamp, it is purely for decoration, no data on at all has ever been taken :x . While this is extremely frustrating, I was hoping someone else may have some data on this bulb. I would be extremely interested in using it on my tank, esp. in conjunction with the 6500K.
For anyone interested, the product code is 22550 M 400LE/V (GES) E40 400W Blue and 22540 M 250LE/V (GES) E40 250W Blue respectively. They also run from a standard MV ballast like the 6500K
Has anyone ever collected data on these bulbs? Would anyone be interested in doing so? Anyone have any photos?
Regards,
Tom

I'd also be interested in these bulbs, any mention of them on their web site?

I don't believe that anyone has done a spectral analysis on this bulb, but I do recall that JT was showing us them when we were at Harbor Aquatics this past spring...

Actually, I was showing you the Ushio Colorlite Blue lamp. It is used in architectural accent lighting mostly, I don't think corals benefit much from it. However, it does a really nice job at supplementing Iwasaki 6500K lamps. Carlos is using them over his acropora/montipora tank and really likes them. We'll see how Sanjay's testing goes.

Ah, OK. Glad to know that Sanjay has a bulb for testing. That bulb was pretty derned sweet when I saw it fired up.

i'm not quite understand. 6500K, 10,000K and 20,000K actually which work better for the coral? I mean not for us. I asked some people but they asnwer is that the 6500K look yellowish so not nice when we look and 20,000K not enough intensity which the aquarium not bright enough to look at for us but no one every reply me which one will do better for the coral?

If you're going for strictly PAR, the Iwasaki 6500 K bulbs and the HQI 10,000K DE bulbs produce similar PAR.
