An infographic analyzes the overall energy efficiency of LED bulbs

An infographic by Chadwicks analyzes the overall energy efficiency of LED bulbs, from manufacturing to the end of its useful life.

The infographic compares compact fluorescent lamps, incandescent lamps, and LEDs. The infographic analyzes different items such as lifespan, energy consumption during use, the energy used to manufacture …

According to the infographic, if a LED lamp requires 9.9Kwh to be made, compared to an incandescent lamp that needs 0.612Kwh, the LED bulb spends much less energy, which leads to greater profitability.

While LED bulbs are more expensive, they have a longer life (between 50 and 100,000 hours for LED lamps, versus 1,000 hours for an Incandescent light bulb). Another advantage is that LED bulbs have to be changed less frequently than incandescent lamps.


Lighting for greenhouses and grow lights

greenhouseThe LEDs have long been recognized for their many advantages over traditional light fixtures. Their long life span, energy efficiency and flexibility have made possible using LED lighting for a variety of applications. LED lighting is now commonly used in the agricultural sector.

Plants respond to the intensity and quality of light. Artificial lighting is frequently used to control plant growth under various conditions. Plants differ in the need for light, and most plants will grow in either natural or artificial light.
If the light is an obvious need for plant growth, it is also one of the least understood for greenhouse cultivation factors. In addition, lighting is often considered less important than the nutrition of plants. However, it is important to supplement natural day light in greenhouses. Many traditional lighting technologies can not be used because they result in excess heat, which can be harmful to plants. Photosynthesis is the use of light energy to decompose water and to transfer hydrogen from it to carbon dioxide in the presence of chlorophyll. For plants to grow well in a greenhouse, there should be a temperature and a light adapted to the plant. These conditions should allow optimal absorption of chlorophyll, essential for photosynthesis and plant growth. In recent years, research has shown that the plants are more sensitive to some particular wavelengths of light. Indeed, absorption of chlorophyll photosynthesis is increased when the plants are exposed to red light (640-660 nm) and blue (450 nm). These studies showed that the absorption peaks of the chlorophyll are within the ranges of 400 to 500 nm and from 600 to 700 nm. Read more
