Standard fluorescents use a reaction in mercury to produce light. Whether in a commercial or residential environment, you can find anything from high-lumen permanent fixtures to fluorescent replacement tubes to household replacement lamps. They also are available pre-installed in fixtures that will replace more traditional, inefficient hardware. As a result, you will be spoilt for choice for what you can get at the right price. The new light technology comes in many different shapes and base combinations to fit a diverse set of fixtures. Advantages of LED Technology Diversity of LED Bulbs In the long run, you will be glad that you have picked up LED bulbs for your home because they are quality and efficient in saving both money and energy. This means that you can enjoy less heat and waste production as well as longer bulb life. The LEDs offer bigger savings which are at least 80% less energy consumption than traditional light. Like an investment, the LED bulbs will eventually pay off. Thanks to the growing competition and developing manufacturing techniques, they are now sold at a more affordable price but it is still more expensive than your regular incandescent light bulb. Instead, you should try to think of it as an investment. When buying a LED bulb, don't expect to save lots of money initially. A variety of colour temperature given by the LED lights to choose from for the perfect lighting effects provides the chance to create the ideal ambience that you want for your room. The warm or the soft white bulb will produce a yellow hue while the bright white will produce white light similar to daylight and what is commonly used in retail stores. There are two popular colours available for LEDs: soft/ warm white and bright white. The LED light bulbs are capable of displaying an impressive range of colours, from bright red to dazzling purple. The diodes work by the recombination of electrons and electron holes in a semiconductor. LEDs is the abbreviation for light-emitting diodes. If you are considering whether LED products are worth the investment to light up your home, here are the things you should know before buying them. LED products can make a huge difference in your room or office in term and reliability and cost-efficiency paving its way to dominating the world in terms of lighting applications. ![]() Readers of this book will understand the principle, concept, design, operation, social roles, pros and cons, costs and benefits of LED lighting for urban agriculture, and its possibilities and challenges for solving local as well as global agricultural, environmental, and social issues.With the development of powerful lighting technology, it is now possible to use LED lights as a light source in your home. The tremendous potentials of LED lighting for urban agriculture are stimulating many people in various fields including researchers, businesspeople, policy makers, educators, students, community developers, architects, designers, and entrepreneurs. ![]() Consideration should be given now to future urban agriculture based on those two fields. It will be largely based on two fields: One is a new paradigm and rapidly advancing concepts, global technologies for LEDs, information and communication technology, renewable energy, and related expertise and their methodologies the other is basic science and technology that should not change for the next several decades. LED lighting for urban agriculture in the forthcoming decades will not be just an advanced form of current urban agriculture. The book contains more than 30 chapters grouped into seven parts: 1) overview of controlled-environment agriculture and its significance 2) the effects of ambient light on plant growth and development 3) optical and physiological characteristics of plant leaves and canopies 4) greenhouse crop production with supplemental LED lighting 5) effects of light quality on plant physiology and morphology 6) current status of commercial plant factories under LED lighting and 7) basics of LEDs and LED lighting for plant cultivation. This book focuses on light-emitting diode (LED) lighting, mainly for the commercial production of horticultural crops in plant factories and greenhouses with controlled environments, giving special attention to: 1) plant growth and development as affected by the light environment and 2) business and technological opportunities and challenges with regard to LEDs. ![]()
