Im a bit on the slow side here so refresh my memory,how does this test you did relate to indoor growing again?,sucessfull indoor lighting is based on lumens per square foot.You should have matched the lumen's, and done a fair comparison before you say an entire technology is bunk.Granted LED lighting is still in it's infancy, but it is the future of lighting.
There are many factors in play here. I recently spent some time in a local grow shop looking for lighting to use on solar panels. Our test was simple, we measured the short circuit current on a 50W solar panel held as close to each type of lighting they had while maintaining full illumination of the panel.
To my amazement a 250W hight output florescent fixture out performed a 1000W metal halide.If you are interested I can explain why. But I would not say metal halide lighting systems are bunk.

Im also curious as to how a 250 watt high output florescent outperformed a 1,000 watt metal halide,a 250 watt T-5HO florescent's lumen output is rated at 20,000 lumens,a 1,000 watt GRO-LUX Metal Halide's lumen output is rated at 150,000 lumens.
HOF lumen per watt conversion = .08
HID MH lumen per watt conversion = 15
In what area did a 250 watt HO florescent outperform a 1,000 watt HID MH .
As for my comparison not being fair,how so? Keeping 3 clones alive would be an easy task for a standard 40 watt incandescent bulb but a 250 led panel was not capable of sustaining a healthy clone
