Exposure to blue light ( 450 nm) provides an innovative method to precisely control blood pressure without drugs," says U Surrey's Prof. Christian Heiss. "Wearable blue light sources could make continued exposure to light possible and practical. This would be particularly helpful to those whose blood pressure is not easily controlled by medication, such as older people."
A paper on the research was recently published in the European Journal of Preventative Cardiology. Also helps people recover from the stress of interpersonal conflicts. 

LED arrays put out approximately 1 joule per minute per cm2, more light per dollar than any other arrays we know of. Our LEDs have a rating of 4000 mcd at 6.4mw. This compares favorably with so-called Cold Lasers and Low-level Lasers. 

• Universal 110-240v AC adaptor (will not work with batteries)
• Array approx. 3/4″x2″x4″
