IntroductionIndia is facing significant growth in electricity
demand and could benefit greatly by using energy efficient lighting
systems. The need of the hour for the country is secured,
affordable and environmentally sustainable energy to meet the
ambitious National Programme of Power to all by 2018.
Lighting is the most visible form of electricity consumption and
lighting load in our country is very high about 18-20% of total
load. By increasing the efficiency of lighting system, there can be
significant energy saving and reduction in peak load. There is a
scope for reducing about 30 to 35 % of the morning and evening peak
demand. 3

Best Practices in Lighting SystemsInstallation of energy
efficient fluorescent lamps (T-5) in place of conventional
fluorescent lamps(T-12). Installation of Compact Fluorescent Lamps
(CFLs) in place of incandescent lamps.Installation of LED panel
indicator lamps in place of filament lamps. Installation of high
frequency (HF) electronic ballasts in place of conventional
magnetic ballasts.Use of high efficacy light sources for reducing
the energy consumption for lighting .Solar Lighting Systems are
providing to be a viable option in rural India because it involves
no moving parts, low maintenance, and are simple to operate.

Merits of high frequency electronic ballastsover conventional
magnetic ballasts
Energy savings about 30 to 50 %. Lights instantly. Improved
power factor (more than 0.90 power factor). Less heat dissipation,
which reduces the air conditioning load. No audible humming sound.
No stroboscopic effect. Operates in low voltage. Less in weight.
Increases the life of lamp.6
Solar Lighting Systems The Solar Lighting Systems are available
in the basic categories which are as follows: (A) Solar lanterns
(B) Solar street lighting systems (C) Solar home lighting
systems

What is CFL?About the CFLWhy should people use CFLs?Precaution
while using CFLsKey features of CFLs8
Switching from traditional light bulbs (called incandescent ) to
CFLs will help to use less electricity at home and prevent
greenhouse gas emissions that lead to global climate change.
Lighting accounts for close to 20 % of the average homes electric
bill. CFLs, last upto 10 times longer, cost little up frontProvide
a quick return on investment.9 Why should people use CFLs?
What precaution should take when using CFLs in home?CFLs are
made of glass and can break if dropped or roughly handled. Be
careful when removing the bulb from packaging, installing it, or
replacing it. Always screw or unscrew the light bulb by its base
(not the glass ), and never forcefully twist the CFL into light
socket .If a CFL breaks in your home follow the clean up
recommendations given by Bureau of Energy Efficiency.10
Low electrical consumption as compared to conventional lighting
productsAbout 80% energy saving over incandescent bulbs.Long life
up to 10,000 hours.It can operate within 130-280 V range.Low cost
of maintenance.High luminous efficiency.Available in different
colors to create desired ambience.Lamps designed for power factor
higher than 0.85.Mercury content within the CFLs (Maximum Limit
being less than 5mg). 11Key Product Features of CFLs

Benefits of using LED light bulbs over standard light bulbsPower
consumption of LED light bulb is only 10% of the standard light
bulb. LED light bulbs having longer lifespan near about 100000
hours.LED light bulbs are 10-60 times more energy efficient than
incandescent light bulbs. LED bulbs require very less amount of
power consumption near about 0.5-0.8 watt/bulb.LED bulbs can
produce many rich and vibrant colors when compared to incandescent
light bulbs. 14
Merits of LED lamps & demerits of filament lamps Demerits of
Conventionally filament lamps are as follows:High energy
consumption (15 watt/lamp).Failure of lamps is high (operating life
less than 1,000 hours).Very sensitive to the voltage
fluctuations.Merits of the LED lamps over Conventionally filament
lamps are as follows:Lesser power consumption (0.5-0.8
watt/lamp).
Longer operating life (more than 1,00,000 hours).
Withstand high voltage fluctuation in the power supply.

Changing Scenario of Lamps
18
Use of energy efficient lamps like CFL, LED, T-5 fluorescent
lamp, etc lead to enormous amount of energy savings which is
estimated as 50 to 80%.Electronic gears of conservation of energy
like electronic ballast saves energy within the range of 10 to
20%.Solar lighting systems such as Lanterns, Street Lights, Home
Lights, etc. can be effectively used, especially in areas of where
lighting is required for shorter duration. This will not only lead
to energy conservation but also encourage use of non-conventional
and environmental friendly energy system.19 Conclusions
