SoalOasis (www.solaroasis.com/)received a patent in 2005 for its SolarOasis
Ruby Gro-Bar technology, the first commercial LED grow lighting technology
available outside the laboratory. Information is in the website or more
details in the Patent (www.freepatentsonline.com/6921182.html). Three
light LED bar is available from SolarOasis for $159.95. The system
features low energy use and targeted light output. System can be adjusted
to control plant growth rate which they say will be of use to commercial
growers.
Would be interesting to try, but still seems to be aimed at the hobby or
small grower now. They also sell specific LED grow or bloom systems.
