yea... u can buy leds in just about any specific spectral ranges.. shit u can even buy leds from radio shack..Im represent the light bar by SolarOasis..im just getting into this market of the home Hobbiest although it is goin to have a bad image for the golbal market. i will just have to be descrit about it if you know what i mean. This product will soon will change the whole industry. look for a website soon pc... i need some sleep


for your question about screens...why would u do that...u have en idea how much a screen for a movie theatre would cost..how would u use it.. i mean... from a HSP bulb u dont see blue or red lights..or anyother color in that matter but the white..and in that light contains the spectrum that plants need..its just that is not eficient enough. over 75% of power goes to heat and some of those bulbs would have to be replaced every 3 to 4 months..with leds you can get the Exact spectoral light that is proven to let plants grow..
