FREQUENTLY ASKED QUESTIONS
Why choose LED? LED Lighting (Light Emitting Diode) is no longer a futuristic technology. Today, LED Lights are available in a wide variety of shapes and sizes. But, why choose LED Lighting over any conventional lighting? Not Sure? Well, let’s take a look at some of the benefits of using LED Lighting both in residential or commercial.
LEDs are tremendously more energy efficient than conventional lighting, reducing not only energy consumption but also your carbon footprint.
LONG LASTING LED
All LEDs have an estimated life of between 20,000-50,000 hours, in comparison to all incandescent bulbs, which have an expected life span of 1,000 – 2,000 hours and a maximum life of 6,000- 15,000 hours for fluorescent bulbs.
COST SAVING LED
LEDs are a type of solid-state lighting -- semiconductors that convert electricity into light. Although once known mainly for indicator and traffic lights, LEDs in white light, general illumination applications are one of today's most energy-efficient and rapidly-developing technologies. ENERGY STAR-qualified LEDs use only 20%–25% of the energy and last up to 25 times longer than the traditional incandescent bulbs they replace. LEDs use 25%–30% of the energy and last 8 to 25 times longer than halogen incandescents.
LED bulbs are currently available in many products such as replacements for 40W, 60W, and 75W traditional incandescents, reflector bulbs often used in recessed fixtures, and small track lights. While LEDs are more expensive at this time, but they still save money because they last a long time and have a very low energy use. As with other electronics, prices are expected to come down as more products enter the market.
LOW HEAT OUTPUT
Most of the energy emitted from incandescent bulbs is converted to heat instead of light. That’s why you’ll burn yourself if you try to touch an incandescent bulb once it’s turned on. LEDs are cool to the touch. Emitting very little heat, LEDs can be used to light delicate objects such as paintings and canvases. They also have the benefit of reducing the work of air-conditioners.
CONTAINS NO MERCURY
All conventional bulbs contain mercury, whereas LEDs contain no mercury. Meaning Eco-Friendly Lights.
NO UV EMISSION
Unlike other light bulbs, LEDs do not emit Ultra Violet Light, which is particularly useful for museum s and galleries, where existing halogen bulbs can cause UV degrading of displayed materials. This makes LED a preferred light source for illuminating artwork, documents, and sensitive materials that can be damaged by UV radiation.
An increasing number of LEDs being introduced are fully dimmable, which mean they are able to adjust their light levels. This advantage also helps for additional energy savings.

LEDs have no warm up time, unlike other conventional bulbs. Therefore, LEDs reach full brightness immediately.
LEDs produce no objectionable hum or buzzing noise.
The light emitted from an LED is easily directed, unlike that of conventional bulbs, so you can direct it exactly where you want it when you want it there.
Color rendering relates to the way objects appear under a given light source. The measure is called the "color rendering index", or CRI. A low CRI indicates than objects may appear unnatural under the source, while a light with a high CRI rating will allow an object's colors to appear more natural.
A light-emitting diode, also known as LED, is a semiconductor light source. Currently the LED lamp is popular due its efficiency and brightness. Many believe that LED is a “new technology”; however, the LED as we know it has been around for over 50 years. The recent development of white LEDs is what has brought it into the public eyes as a replacement for other white light sources.
1907- H.J. Round reports light emission from a crystal detector.

2007- Italian village, Torraca was the first place to convert its entire illumination system to LEDs.
2008- Audi is the first car to use fully LED headlamps.
2011- LEDs have become more efficient, so that a 6-watt LED can easily achieve the same results as a standard 40-watt incandescent bulb.
Hopefully, this gives you a better idea about Why to choose LEDs over any conventional bulbs.
