Light emitting diode (LED) lighting fixtures usually have higher luminance and yet consume less energy, thus inspiring manufacturers of many commercial and industrial applications to switch to these. Companies that currently use this technology report that they consume approximately 48 per cent less energy than when they used conventional lighting technology. LED technology is, therefore, being constantly upgraded to meet the requirements of newer applications. To cope with this demand, new LED lighting products are also being manufactured and are flooding the market. Since the pace of technology development is so fast in the LED space, enabling it to cater to newer applications, an LED lighting product that is new today could be outdated the next month. So it is difficult to say what’s new in the market ‘today’.

Wednesday, JUne 13, 2012: What’s new in the market

Different types of LED lighting products are available in the market, ranging from retrofitted bulbs, tubelights, flexible and rigid strip lights, to a number of downlights and spotlights. The range is so varied, that a buyer can easily get confused. So it is better that you first assess your requirements and do some research before going out into the market. While there are products from reputed brands, there are also unbranded products from local manufacturers and imports from China, Taiwan and

Sujana’s LED downlight

other countries. So buyers need to have some basic knowledge about the technology and about the credibility of the players in the

for offices and the retail segment, is an effective replacement for conventional CFL solutions, resulting in significant power saving and reduced operational costs. “GreenLED is a breakthrough offering that combines modern product design, the latest LED technology, reliable heat management, with low glare and good quality lighting,” explains Indranil Goswami, head, lighting application services, Philips Lighting India.

Sujana Energy provides a wide range of downlights and troffer lights for the commercial segment. “The higher lumens per watt for the total system, and our focus on competitive pricing, is what sets these lights apart. In all, we have seven new downlight models and five new troffer models in the range of 3 W to 21 W

BN Sinha, director, Candela Lighting Systems Pvt Ltd

and 20 W to 60 W, respectively,” says Hari Kiran Chereddi, managing director, Sujana Energy Ltd. Sujana claims its lights to be of high quality in terms of optics, electronics and fixtures, with excellent energy efficiency. “Our new products generate higher lumens while consuming less power. Maintaining the junction temperatures well under the limits to ensure the longevity of the LED is the key here. The lower wattage LEDs that have a much higher efficacy of around 140 Lm/W

Bipin Mehta, proprietor, Hi Tech Luninaries

are used to get these outputs from our products. The lower driving currents ensure that temperatures generated are much lower than typical values, which, in turn, affect other parts of the system and the pricing,” explains Hari Kiran Chereddi.

As per company claims, Sujana lights can reduce energy consumption by 50 per cent. And this figure can be further increased by integrating the LED lights with other automation techniques like dimming and switching on/off, based on occupancy. The most common method of lighting automation control involves using motion sensors to manage the on/off state of the lights. Certain software are being used to calculate the exact lighting requirements in commercial spaces so as to minimise energy wastage and maximise the efficiency. “LED devices are undergoing continuous technological innovations to increase high luminous efficacy and a high Colour Rendering Index (CRI). LEDs with an efficacy of

G Gururaja, director, operations, Avni Energy Solutions Pvt Ltd

around 100 Lm/W are common, and there are even commercially available devices that offer more. Recognising that such innovations are the need of the hour in the commercial space, we are working in this direction and have already started implementing automation in our range of

Hari Kiran Chereddi, managing director, Sujana Energy Ltd

products,” informs Hari Kiran Chereddi.

Avni Energy has launched many new products in the indoor commercial lighting segment. Its new range of LED downlights of 5 W, 7 W and 12 W power are aesthetically designed with die cast aluminium fixtures and high efficiency drivers that have high voltage cut off protection (300 V). It has also launched a replacement for 400 W HPSV/MH lamp with 200 W LED light for high mast light. “We have come out with an 18 W LED tubelight with a lumen efficacy of 80 Lm/watt, which complies to CE standards and has been tested and certified by UL for lumen performance (LM79),” informs G Gururaja, director, operations, Avni Energy Solutions Pvt Ltd.
