Benefits of LED Lighting * extremely energy efficient‚ consuming up to 90% less power than incandescent or halogen bulbs and up to 50% less than fluorescent or CFL. * less heat emission‚ therefore loading on air conditioners is reduced resulting in further electricity savings. * long life span thus reducing maintenance and lamp replacement costs and lower long-term operating costs. * environmentally friendly as they do not contain toxic mercury or any other hazardous materials. Secondly

Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

eyes. What shapes this novel is the use of dark vs. light throughout major events of the novel to create the scene and feelings of the events occurring throughout the novel. In the novel‚ The Great Gatsby by Fitzgerald uses the leitmotif of dark and light to creates an overall feeling of hope or despair in Gatsby’s character during events throughout the novel. The first representations of light in the novel seem hopeful. The green light seen from his dock‚ where Gatsby would spend most

Light in August‚ a novel written by the well-known author‚ William Faulkner‚ can definitely be interpreted in many ways. However‚ one fairly obvious prospective is through a religious standpoint. It is difficult‚ nearly impossible‚ to construe Light in August without noting the Christian parallels. Faulkner gives us proof that a Christian symbolic interpretation is valid. Certain facts of these parallels are inescapable and there are many guideposts to this idea. For instance‚ there is Joe

the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other

Light at the End of the Tunnel When I graduated from high school I was like all the other low-life‚ lazy teenagers‚ not yet ready to be taken from my parent’s wings. I never realized the importance of furthering my education. I just knew I could “do big things” working as a Sales Associate at 7-Eleven for the rest of my life. After my first child it began to dawn on me that an education would be the only thing that would let me provide for my family in the ways I wanted to. How scary is that I
