Have been using the ultra sun for awhile. It was time to replace but the bulb i picked up from the local store took home & didn't work. Brought it back & they were now out of the ultra sun so i went with the eye super hps which was a few bucks more but i had to get a bulb so i got the eye. I noticed the eye has 88,000 lumes & the ultra sun has 90,000. I guess my ? Is the eye gonna be something i will be happy with? The light spectrum on the eye has more blues & greens in it which i would i guess would be good if i veg with it but i won't be. Just flowering with it. Any input would be great. Thanks ahead. I could still return the bulb and order a ultra sun if it's recommend. Thanks again guys & gals........oh, i will not be using a digital ballast with it either which probably makes a difference.
