I just got in the Helios 250W DE 20K bulb from premium aquatics. I have a new Phoenix next to the Helios. The Helios is similar in color but brighter. This is going to be my new bulb. I am runnging it on an PFO Magnetic M80 (HQI) ballast. Nice Blueish white bulb. It more blue than white. I highly recommend this bulb. I have read good things about Helios so I figured to pull the triger. I guess Reefermadness and Fragfarmer uses these also. I tried to get a comparison picture but the picture does not do it justice.
