    630w DE - CMH?

    I'm researching lighting for my first set up and was wondering if anyone has tried the de cmh 630w from http://growershouse.com/growers-choice-630w-de-double-ended-ceramic-mh-cmh-lamp-4200k It's not a dual 315w cmh like I am used to seeing I have not been able to find any info on these. please...
