Review on Straight Bi-Pin Daylight Octron Fluorescent Tube by Frank Tyrance

After a very long search for replacement bulbs for my SunBlaster 3' ballasts that were the right color temperature and brightness for plant growth I came across these. While I can't confirm their longevity yet, I used a light meter to test their brightness against my SunBlaster T5HO bulbs - and they are brighter indeed! The color temperature also looks correct. They fit perfectly in my 3ft ballast. Please keep up the good work - this size is very hard to come by!
