The light-emitting diodes (LEDs) light up immediately, like an incandescent bulb and is a source of light that is reliable, instantaneous, and can be dimmed accordingly. They last up to five times longer than the CFLs, which can literally last a lifetime. Moreover, these are user-friendly as they do not contain mercury and are available in soft, warm, and bright white hues. LEDs work well both indoors and outdoors because of their durability in the cold environment and they are safer, studier and easy to install.
How a LED works? The LED is an electronic light source that works by the effect of the electroluminescence. When a semi-conductor diode is turned on, the electrons recombine with the holes, and the energy is discharged as light.
An average household spends about 5% of its energy budget to lighting. Switching to energy-efficient lighting is one of the easiest ways to cut the energy bills.
New light bulbs: what’s the difference? Traditional incandescent bulbs use a lot of energy to produce light and over 90% of the energy is wasted as heat. Whereas, the energy-efficient light bulbs use about 20%-80% less energy than the traditional incandescent, saving a lot of money.
What is Color Rendering Index? The Color Rendering Index (CRI) is measuring the ability of a light source to stimulate the colors of various objects precisely along with the sunlight. Though there are critics of the subjective color used, the CRI is extensively utilized as a measurement of the quality of the light.
