n an enlightening customer story,

Philips on its website shares the ex-

perience of State Bank of India, Agra

Branch, which recently switched to LED

lighting. The bank was looking for a light-

ing 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 mar-

ket 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 fluo-

rescent tubes, keeping

the ballast and fixture

unchanged. Thus, the

installation cost of LED

tubes is nearly negli-

gible. 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 elec-

tricity 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 con-

sumption. 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 recon-

figuration of the setup. Users just need to
