The quality of LEDs is there now, the only barrier to entry for me is upfront cost. I suspect prices will drop substantially over the next few years and in terms of quality, HID and LED buds are more or less equal. If I were to set up a large grow room now, I would buy HID fixtures up front and eat the higher electric costs, then replace them one by one as I'm able to. I have a fondness in my heart for HIDs, esp the CMH light, which looks lovely in the winter, but they are nearing the end of their days...once the big price drop happens, they will be but a candle in the wind...
