Light-emitting diode (LED) is gaining popularity as the lighting technology of choice for many commercial and industrial applications. This is because it is much safer, cheaper and energy-efficient than other lighting sources. LED lighting fixtures usually have higher luminanc and yet they consume lesser energy, thus inspiring many commercial and industrial establishments to convert into LED lighting. Companies that currently use this technology report that they consume approximately 48 per cent lesser energy than with conventional lighting technology. LED lighting is visually appealing as well.
LED technology is therefore being constantly upgraded to meet the requirements of newer applications. “For commercial purposes, the most effective LED lighting would be MR16, MR11 and downlights of various wattages. These are used in showrooms, shopping malls, offices, factories, etc,” says Ravi A.V., general manager, LED division, Nichia Chemical (I).
What’s new in the market
Different types of LED lighting products are available in the market, ranging from retrofitted bulbs, tubelights, and flexible and rigid strip lights to a number of downlights and spotlights.
An ‘LED product’ generally means a product with an upgraded version of LED technology and some specifiation changes in its components to make it more energy-efficient. he pace of technology development in the LED space is so fast that an LED lighting product that is new today could be outdated the next month. So it is very difficult to say what’s new in the market today.
A majority of commercial lighting involves recessed or canned lighting, which releases very little heat. These provide a focused, high-intensity light where it is needed the most. They can be operated by dimmer switches that help tailor the lighting to the needs of the individual.
AMKA Lighting has added new products to its wide range of LED recessed downlights, spotlights, surface lights and power LED lamps, which the company claims to be a replacement of the MR16 halogen lamp.
“These power LED lamps can save at least 85 per cent of the energy normally used and have a working life of 20,000 hours,” informs Sanjive Jain, managing director, and S.C. Joneja, director, AMKA Lighting.
Binay Opto’s model 600² power LED luminaire is designed for recessed fitting and is suitable for installation into a panel grid. “It offers 95 per cent luminaire efficiency and saves 75 per cent more power than comparable fluorescent tubelights,” explains Kumar K. Rohatgi, founder and technical advisor, Binay Group.
LED retrofit bulbs, which can conveniently replace the GLS bulb and be installed on existing lighting fixtures without any additional expense, are new in the market. These globe-shaped bulbs also come in RGB colour changing models and with a remote control.
In October 2010, Philips Lighting India launched a range of LED bulbs for consumers in the Indian market. These indigenously developed LED bulbs adhere to India-specific environmental and infrastructural challenges such as voltage fluctuations, energy spikes and an irregular power supply.
“Unlike other lighting technologies that are electrical, LED lights are electronic devices. LED bulbs, like other LED sources, are one of the most sustainable lighting solutions. These are based on low-voltage technology and have a lifespan of 50,000 hours,” says Aditya Khosla, director, Sanarti.
New additions from Sanarti include LED T5 and T8 tubelight series, LED bulb series and LED panel light series. T5 and T8 tubelights are an energy-efficient replacement for traditional fluorescent tubes and have an option of inbuilt or separate ballast.
Almost every LED player offers different kinds of downlights. “We have developed downlights using a special diffuser where the light source is invisible. Another new product is the MR16 version which is dimmable,” informs G. Gururaja, director-operations, Avni Energy Solutions.
“An MR16 LED bulb is a multi-faceted reflector (MR) that is usually high-powered but consumes only 4 watts. It emits the same light output as a standard 50W bulb,” informs Jaweed Khan, CEO, Hovel LED Lighting. The company has a series of MR16-compatible modules.
Binay Opto’s retrofit power LED tubelights can replace an existing T8 fluorescent tube. “We have filed a patent for this product. There is no need to remove the electromagnetic choke. The unit can run through the choke or directly without the choke,” explains Rohatgi.
Other players who offer tubelights are Sanarti, AMKA and MIRC Electronics.
“Our LED lights are anti-glare with a higher light output and lesser heat dissipation,” says Avnish Jauhari, business head, lighting, MIRC Electronics.
High bay LED lights are also in demand, as these lights have a much longer working life than conventional fluorescent and incandescent lights. On an average, you can expect these lights to last ten times as long as a typical compact fluorescent bulb.
