Apparently Sunshine Systems is having a summer special on their GlowPanel 45. I used their 14 Watt model earlier in the year for supplemental lighting and it worked fairly well, I was thinking about upgrading for overwintering... still think I'll probably go with the GrowUFO, as the savings on these panels isn't that much considering they're about 25 dollars cheaper on amazon with free shipping.

ASFx was doing a comparison between this model and the HydroGrow LED 50W Penetrator for those curious about the sort of results you can expect (Link).
