There are some startling claims about LED lights, the latest and most efficient of lighting technologies. Misinterpretation of research in this area causes fears. Can LEDs really do that much harm to health?
In our growing and developing cities, we spend time outside at night as well as during the day. Life continues until the late hours after sunset, and we need lighting to maintain our safe and quality lifetime at night. Outdoor lighting is a part of the landscape and built environment...
A light bulb we use at home everyday emits about one quintillion photons per second and hundreds of billions of photons included in the light are coming into our eyes. The light energy delivered to the eye plays a key role in maintaining normal biological activities including visual perception, circadian...
Demand for energy efficient LED bulbs is picking up. However, there have been complaints that energy efficient light bulbs cause headaches. According to a professor at England’s University of Essex, LED lights flicker around 100 times per second, which is known to cause headaches and or leading to pain or...
Two Austria-based scientists have invented an LED lamp known as Lucia No 3, that provides users deep relaxation, dream-like situation and various transcendental experiences. Lucia No 3 is a device that consists of a lamp surrounded by LEDs hanging from a pole structure, which is attached to a computer.
University of Arizona has studied the effects of LED light therapy, and taken a step forward towards the potential use of light as a treatment for some forms of chronic pain, by studing the impact of visible-spectrum light from LEDs on the sensory thresholds in rats. Researchers have also studied...
