Has anyone done any investigation on the new plasma light fittings? There is an advert in the Coral Mag for the Seashine light series for aquariums. They claim to provide 180% higher PAR values than 10,000K 400W metal halide aquarium lights and up to 500% higher PAR than standard MH's.
There is a brochure available at Stray Light Optical Technologies with full specs and performance graphs.
I am communicating with them with regard to pricing.
