Despite their comparitively higher energy consumption, many people are more comfortable with fluorescents than H.I.D. lighting.
Whether or not fluoros can generate the light intensity for flowering is the subject of much debate.
We employ non-standard ballasts to accomplish this. This model tested out at 14,000 lumens with a digital light meter. It has been subjected to othertests as well. As you can plainly see from the pic, the light distribution is excellent!
