Here's a link to Steve and Toni Ruddy's page that shows some comparison pics for the Iwasaki 6500k, the Iwasaki 50,000k aqua, and the 20k coralife. I am not familiar with the spectral or visual differences between the coralife and radium/osram 20k's, but this looked to be a good comparison. The 50k looks like it would be some great MH only lighting providing you had enough watts.

Here's the link:

The "50k" is obviously WAY off, and is merely a marketing term (man that gets irritating ). But regardless, looks good to me.

PS-been busy lately, and haven't had a lot of time to post, but bear with me, "I'll be back."

Gotta say I like the 150W 6500K Iwasaki Color Arc plus URI VHO actinic and the 150W 50000K Iwasaki Aqua the best so far...

Cool link...

Pretty cool that they are only about 15 minutes north of me as well.
