That is basically what I said two post before the one you quoted. Its just at this point I dont see hps bulb getting much better, and LED is. In the near future I expect LEDs will be worth a go. Just not at this point in development. If a single diode can create a few hundred thousand lumens, the intensity of the light cant be argued. The thing is will we ever have access to those diodes? And when we do, if we do, we just have to hope they arent a few thousand dollars a piece. Imagine 5 led diodes producing 1 million lumens. You wouldnt be able to look into the room without a welding helmet on. How many thousands of watts of hps would that take to produce that many lumens? Around 5 or 6 thousand at least I would think. And what a bitch it is to cool that room would be. That issue wouldnt be there with the LEDs. Ahh what the future may hold for us growers COULD be amazing. But at this point, I wouldnt fuck with LEDs. Unless they are used for vegging only.
