I hope this technology continues to improve. The energy cost savings, low heat production, wavelength specific options and life span are important factors to me. I think with more time and R&D, the LED will be leading the way indoors. Just like when Pioneer introduced the plasma TV. It was so overpriced not many could afford it and saw no value in watching a crystal clear picture, until they saw themselves. If they could get the price point to that of a MH/HPS setup, they would gian more of a market share and transitioning people to at least test it.
The "shop" owner told me he hated the light. It burned his basil and caused leaves to fall off his plant. In addition to that, the light cost 1300 bucks! If I'm going to pay that kind of money, my plants better grow to the moon!
