Big fan of the new optics, I've been wondering when someone was going to start utilizing "Mini kessil" style dome optics to disperse LED lighting..
Right now, T5 is still better than LED, and it's 100% because of the light dispersion and optics (and ease of use... but product templates are very usable). For LED's Research and Development steered towards light dispersion and optics being a chief concern can and will kill T5.
