Man everyone was swearing by the Philips green power. It took me forever to find the fucking thing . I only put it in the nanolux ..the dudes told me the bulb the gavita comes with is good. I am hoping for a better yield, even harder bottom nugs and less larf I would be pleased . But definitely have smaller top nugs under the DE it seems . I do notice the footprint is pretty wide , I haven't used a par measurement but it seems to handle 5x6 better than the adjusta wings . But smaller nugs than the raptors
