In an enlightening customer story, Philips on its website shares the experience of State Bank of India, Agra Branch, which recently switched to LED lighting. The bank was looking for a lighting solution that would decrease energy consumption and save costs while also creating a soothing ambiance. LED lighting provided the bank with an efficient, long-lasting, ambient, high-output solution and consequent energy saving of 50 per cent.
LED lighting solutions come in various form factors, including bulbs, tubes and floodlights. Here we talk about LED tubes only. LED tubes were introduced in the market in the early 2000. Currently, the retrofit LED tubes market can be divided into three categories—Type A, Type B and Type C. Type A being the most popular of the lot, here we discuss their benefits and challenges.

Benefits of Type A LED tubes

Type A LED tubes replace the existing fluorescent tubes, keeping the ballast and fixture unchanged. Thus, the installation cost of LED tubes is nearly negligible. Other benefits of Type A retrofit LED tubes are mentioned below.

Slash electricity bill by 50 per cent

Type A LED tubes come with three of the most sought-after features that reduce expenses in the long run. These include high efficiency, long usable lifespan and less maintenance requirements.

LED tubes significantly cut down the energy consumption, and thus, your electricity bill. On an average, genuine-quality LED tube lights can help users to lower electricity consumption by 50-80 per cent compared to CFLs and incandescent. Unlike the 360-degree emission pattern of fluorescent tubes, Type A LED tubes emit light in a single direction, avoiding unwanted loss of energy. Lower energy wastage also implies lower power consumption. Therefore LED tubes consume less power than CFLs and incandescent light bulbs but deliver brighter output. The light efficiency of LED tube lights is represented in lumens per watt.

Type A LED tubes with a genuine-quality driver can run for more than 50,000 hours in suitable conditions, while the lifespan of fluorescent or incandescent tubes is limited to within 10,000 hours. That means there is no need to frequently replace or fix damaged tubes.

Easy installation

Type A retrofit LED tubes don’t require rewiring or reconfiguration of the setup. Users just need to replace the old fluorescent tube with the new LED tube, keeping the fixture, ballast and all other pre-existing components intact. The tube itself comes with an integrated driver that co-exists with the ballast. This helps to reduce labour costs and efforts, injury risks as well as installation time.

“The installation cost of Type A LED tubes depends on a few factors such as the existing ballast’s compatibility with the LED tube,” says Rajeev Kr Rohatgi, director, Binay Opto Electronics.

Environment-friendly

LEDs are devoid of mercury or any other harmful chemical, which makes them very safe for use. LED tube lights also substantially reduce the emission of carbon dioxide, ultraviolet rays and other pollutant elements compared to conventional lighting products. Incandescent lights waste 90 per cent of the electricity they consume as heat, producing carbon dioxide in the process. Fluorescent lights, on the other hand, contain mercury—a hazardous liquid metal that can cause some serious health problems if released into the atmosphere.

According to the National UJALA Dashboard website maintained by Energy Efficiency Services Limited and the Ministry of Power, India, as of April 2017, over 1.8 million LED tube lights were distributed throughout India. This initiative resulted in reducing carbon dioxide emission by over 67,000 tonnes and energy consumption by almost 82.4 gigawatt-hours.

Cooling and calming effect

LED tube lights have a high colour rendering index range, which reduces stress on the eyes while working. Additionally, LED tube lights are dimmable, allowing users to set the ambiance in their home or office environment. The various colour temperature options determine the intensity of the light output, ranging from reddish, orange, yellow, white up to bluish-white.

Colours emitted by LED tube lights have a very significant effect on the human health and productivity. Bright bluish-white LEDs have an energising effect on users, while warm yellowish light has a calming effect.

“The colour of white is used for human productivity. The ideal lighting system is one which changes in consonance with the sun’s colour. In many offices abroad, when you first enter the office, you find very bright bluish-white lights. This level of brightness at the start of the day acts as your first cup of coffee to kick-start your brain. During lunch hours, the brightness of this light is reduced to warm yellowish colour, to allow the staff to relax. This whole concept of controlling the brightness of light is called ‘Human-Centric Circadian Lighting,’” explains Rohatgi.
