Sorry I haven't been around. I'm working on new panels with 100w diodes in them and I had to go to the optometrist to get special temporary glasses because my dumb ass stared at it for too long. I'm better now!

Anyways, for me, I'm perfectly content with what gets grown under my LEDs. Right now, the tech is most certainly out there and surpassing T5 units as long as they are properly configured. Poor configuration = poor performance. Don't count on HID being 'out' just yet, as we're still waiting on 150+ lux/w outside of the lab.

For now, at the current level of LED tech, 300w LED ~= 600w HID for flowering/fruiting. 120w LED ~= 600w HID for veg. As long as you distribute it around and keep your plants smaller, you can actually yield more as you've got more canopy of cola.

In fact, I'm about to take maximum advantage of that sort of situation in my growing area - I've just finished working on a new SoG system. Here is a picture for you.

Overall, LED is pretty much 'there.' but you have to find the right people that know what they're doing. Once the tech gets good enough, any Joe Schmoe can pick up a white panel and grow whatever they wish better than an HID.

And Canna's correct, there is no 'color temperature' to speak of. If you wanted a relative value, 12,000K minimum minus green is a good approximation.
