yeah... i think i just had a bad batch... but like i said, i went thru 6 bulbs.
sanjay's data shows around 11000k for CCT after 100hrs burn in... this is why i went to them.. that and the similar par to the overdriven 400w radiums... but i couldnt come anywhere close to 11000k except the 1st day... then day by day... more and more yellow. This was on m58 ballasts (still tested at ~11000k by sanj)
on the note of XM.. i have 150wXM10kDEs on m81 ballasts for my 75g softy/lps tank... those have served me well.
people have said with chinese bulbs it is just a crapshoot... something about quality control, etc that is all beyond me.
who knows.... maybe when it is time to replace the evc's over my tank... i may get a bad batch of those. Just getting 6 XMs in a row that burned in yellow left a bad taste in my mouth.

actually... go here ... http://www.reeflightinginfo.arvixe.com/select2lamp.php
plug in 400w evc 14k se on hqi.... then put in 400w readium se on hqi..... looks like the 14k is still bluer by the spectral plot even though the radium is a 20k. Both CCT's are 0, meaning off the chart... so you dont have that to go by.

thanks
ran on HQI.... i have in the past, but i dont currently(i have just about every ballast made from trying different lighting over the years)
these are on PFO magnetic pulse start ballasts... regular PFO magnetic will run them the same way. believe it or not, the pfo hqi actually underdrives the bulb a little by comparison.
mag/mag-pulse .... ppfd 204, CCT 8600, and 485w
mag hqi..................ppfd 173, CCT 8441, and 450w (still very good)

in that pic... about 8 colonies have been removed... i am trying to open up the tank for more room for corals to grow.
i have a coupla corals growing outta the water and i wanna reduce the 'scape height by half. i intend to reduce my stony load by about half too (dont know if i will be able to part with that many)
