I built some of those early prototype lights. It was nothing remotely close to cost effective at the time, but I was doing a lot of work with LEDs and thought it would be interesting to see how the power consumption and heat management problems would improve using LEDs. It was enough to convince me that LED grow lights were absolutely the way of the future.

Now that cannabis growing is legal here in Washington, though, it will be interesting to see whether outdoor growing can compete. The advantage of being able to precisely control your plant's growth cycle is pretty significant even compared to getting your power for free from the sun.
