Would like to buy red and infrared light therapy for health, medical uses.  I need approximately 30 LEDs per device and another device 100 to 500 LEDs.  Both will be infrared or red or both.  Email me wavelengths and links to pictures and USD price for 50 units plus all shipping costs to arrive to my location in Montgomery, AL 36109 USA.  Also email me a price for one if you do not send samples for free.  I also need my designs made that include a fan, timer, and overheat protection circuitry.  I am an electrical engineer.  I need 500 per year.
