Save Energy…Use Energy Saving Lamp

IntroductionElectricity crisis is a common phenomenon in our country. It’s a regular sufferings for

the people of different locations of the country.

The government has assured the general public about their efforts to ease the crisis.

But that requires large amount of money and time for a total and complete

implementation. In the mean time, there are a lot of initiatives exist that general

population themselves can undertake to ease the electricity load. In this process, to

some extend, the electricity crisis will be solved eventually.

The first step would be and awareness among people to stop all wastage of electricity

and drive towards some savings. Hereby, using CFL(Energy saving lamp) is nothing but

a consequence of this national effort.

CFL is a compact form of florescent lamp ensures 80%

of energy saving compare to equivalent light output of

conventional incandescent lamp.

CFL is a kind of Energy Efficient Lamp which gives us

required lumen by consuming fewer watts. Incandescent Lamp Compact Florescent Lamp (Energy Saving Lamp)

What is CFL?

• A compact fluorescent lamp (CFL), also known as a compact fluorescent light is a type of fluorescent lamp is designed to replace an incandescent and can fit in the existing light fixture formerly used for incandescent.

• A compact fluorescent lamp used outside an office complex.

Energy Consumption

• The chart shows the energy usage for different types of light bulbs operating at different light outputs. Points lower on the graph correspond to lower energy use.

Comparison with incandescent lamps

■ Net Saving for 10,000 Hour = BDT 2183

■ Yearly Saving (Considering 3000 Hour/year) = BDT 728

■ Monthly Saving = BDT 60.67

■ Investment return = 4 months (Approx.)

ENERYPAC CFL:

■ Standard Warranty = 1 year

■ Payback = 4 months (Approx.)

■ Net Saving (Per Year) = BDT 485

■ Investment gain on BDT 250 = 194%

80% ENERGY COST SAVING: CFL consumes about one fifth energy comparing with incandescent bulbs but

same as bright. Substantially reducing energy expenses for lighting up to 80%.

A dollar you save is same to a dollar you earn. 

Features of CFL

LONG LASTING 10,000 HOURS:

CFL bulbs lasts 10 times longer 10,000 hours comparing with

incandescent bulb for an average of 1000 hours. It features

improved efficiency and drastically reduces the troublesome

task of bulb replacements

COMPACT SIZE & LIGHT WEIGHT :

Comparing as old Radio with today’s transistor Radio. Thanks

to our advanced technology ballast featuring a small choke coil,

power transistor and capacitors makes our bulbs very compact

in size and lightweight.

Luminous Efficiency > 50 Lm / Watt

Power factor > 0.5 Leading

% of Saving > 80%

Long Lasting 10,000 Burning hours

Operates at a voltage range 150V – 250V

Color Rendering Index > 80%

Initial Lumen > 80% of Steady state Lumen

• Can normally work within a voltage range of 150V-250V or even lower

than that.

• CFL keeps lumen output almost same with lumen variation

National Savings:

Total Power Consumption : 4000 MW Power Requirement for Lighting Purpose (30%) : 1200 MW Energy saving possibility through Using CFL (80%) : 960 MW Energy saving in 1 year time frame : 240 MW (Considering 25% coverage of the total energy saving per year)

Required number of energy saving Lamps (CFL) : 100,00,000 pcs (Approx.)(to save 240 MW electricity)

Total cost for lamps required to save 240MW : BDT 250,00,00,000

Power Generation Cost per MW : BDT 5,25,00,000Power consumption cost for 240 MW : BDT 12,60,00,00,000

Recommendation: So, if we use CFL of BDT 250 Crore, no need to establish a power plant of BDT 1260 crore for lighting purpose.

National Saving

Environmental Benefits:

Less energy consumption saves more

energy generation. Each energy saving

lamp (CFL) prevents production of

100kg of CO2. Energy saving lamp

(CFL) uses less energy means less CO2

emissions, a relief of global worming

and air pollution.

Environment Friendly

Environmental Benefit Calculation:

Environment Friendly

Current price for CO2 in international market : 10 USD or BDT 700

Prevention of CO2 emission through using 10000000 pcs of CFL : 10,00,000 MT

CO2 trade benefit (Total) : BDT 70,00,00,000

Per Lamp CO2 trading benefit : BDT 70

SAVE ENERGY = SAVE MONEY
