Led light bulb www.ledmyplace.com
What is a LED? The LED stands for light-emitting diode. LEDs are semiconductors that produce light more efficiently unlike the traditional light sources. When electricity is passed through the led bulb, it emits energy in the form of light. These semiconductors are injected with chemicals that decide its light colour. The LEDs convert majority of energy passed through them to light, as against the incandescent bulbs that produce light as a by-product of getting heated. For this very reason, the LED lights can be 90% more energy efficient unlike the traditional filament light bulbs. LED lights have been in use widely as displays and indicator lights for nearly 4 decades. But only recently, because of more innovations in LED has led to wide usage for general-purpose lighting. The high brightness and point-source features of LEDs have made them the first choice for places where visibility and dependability are of utmost importance.
Things to consider when choosing the Led light bulb Because of their serval advantages over the traditional incandescent and fluorescent light bulbs, the LED lights are poised to take over as the leading lighting option. When selecting and buying the led light bulb, buyers need to learn the new terminology and take into consideration all factors which they don't have to think about while purchasing the traditional types of light bulbs. Given below are some basic background and buying considerations for first-time buyers of LED light bulbs.

Things to take in to account while choosing the led light bulb
Cost effectiveness
While the initial cost per led bulb is high, the total lifetime cost of a led light bulb is lower when compared to equivalent incandescent and CFL bulbs. Considering the energy costs as well as the time and resources needed to replace incandescent and CFL bulbs, an LED bulb that can last 80,000 hours has a much lower lifetime cost.
High Colour Rendering index (CRI)
The finest LED chips can emit light with Colour Rendering Index (CRI) of 85%. The CRI is a quantitative measure of the capability of a light source to reproduce the colours of diverse objects faithfully in comparison with an ideal or natural light source. Thus, the led light bulb that use top-quality LEDs will last much longer than the traditional bulbs.
Dimmable feature
LED light bulbs cannot be dimmed with traditional dimmers, because the LEDs require constant current to operate. Because of this reason, if a standard dimming method is applied, the led light bulb will flicker at regular intervals, or worse, simply will not work. To dim an LED light, a 0-10V dimming module is needed to "trick" the LED into emitting less light. In theory, all the LED lights are dimmable with this module. www.ledmyplace.com

Lumen quality
When compared to LED light bulbs, it is necessary to get to know you need what is lumens. The lumen is a standard unit uses to compare LED light bulbs to standard bulbs, such as incandescent or halogens. Roughly, a lumen is a measure of brightness and the lumen quantity is vital, perhaps maybe more important is the lumen quality, i.e., luminous efficacy (lumen/Watt). The Led lights available today have a luminous efficacy between 60-70 lumens/watt.
