Save Energy… Use Energy Saving Lamp

Introduction Electricity crisis is a common phenomenon in our country. Its 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.

Lights Others 70% 30% Electricity Consumption

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 SL. No. ParametersCFLIncandescent 1Luminous Efficiency Lumen/ watt Life Time (in burning hour)10,0001,000 3Energy cost or 10,000 burning BDT 2.90 / kwh Purchase cost for 10,000 burning hour Operation cost (3+4)

Comparison with incandescent lamps Net Saving for 10,000 Hour= BDT 2183 Yearly Saving (Considering 3000 Hour/year)= BDT 728 Monthly Saving= BDT 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 todays 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. Features of CFL

BULB TECHNOLOGY DIAGNOSIS (1) Glass Tube (2) PTC Thermistor for instant flicker free starting (3) Radio interference suppressor (4) Switching transistors (5) Lamp current stabilizer (6) Electrolytic Capacitor for flicker free operation (7) Fire retardant PBT body housing (8) Nickel plated Brass base Components

CFL Specification Parameters Standard Value Luminous Efficiency> 50 Lm / Watt Power factor> 0.5 Leading % of Saving> 80% Long Lasting10,000 Burning hours Operates at a voltage range150V – 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 Wide Voltage Operation Range Lumen Variation Against Voltage Fluctuation

4000 MW National Consumption 30% of 4000 MW = 1200 MW Lighting Consumption 1200 MW Lighting National Saving

80 % Save 1200 MW Current Lighting Load 960 MW 240 MW 20% Consume Switching to CFL Power Consumption Reduces to 80 % National Saving

Four years National Saving Plan 960 MW 240 MW National Saving 240 MW

1 Crore CFL = 250 Crore TK 240 MW Power Plant costs 1260 Crore TK. Or National Saving

1000 Crore TK / year (Approx.) National Saving

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 5,25,00,000 Power 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 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 Ultimately
