### A CALCULATOR FOR BENEFIT ESTIMATION FROM POWER-SAVING LAMPS

To know, how much you win from choosing contemporary power-saving «AKFA Lighting» lamps, let’s calculate their benefit on a real example.

Lamp Type | Power-saving | Common |

Power | 7 W | W |

Number of lamps at home | ||

Lamp working time per 24 hours |
h | |

1 kW/h Cost | sums | |

Power consumption per hours | ||

Power cost per hours | ||

Lamp cost | sums | sums |

Economy per 1 year ( hours): | ||

(10 lamps х 100 Watt х 6 hours х 365 days): 1000 (converting watt to kilowatts) = **2190 kW**.

The quantity of consumed kilowatts, 2190, is multiplied by the tariff rate of 86.3 sums = **183 084 sums**.

It turns out that the family budget annual expenditures are **183 084 sums**for the light of lamps only!

If we multiply the same figures for **power-saving lamps**, we will have the following:

(10 lamps х 20 Watt х 6 hours х 365 days): 1000 (converting watts to kilowatts) = **438.00 kW**.

The quantity of consumed kilowatts, 438, is multiplied by the tariff rate of 86.3 sums = **36 616.8 sums**.

Compare:

**36 616.8** sums against **183 084 sums**! That means, replacing the lamps in your home by the modern power-saving «AKFA Lighting» light sources, you will save **146 467.2 sums** only in one year !

Now let’s calculate the family budget expenditure, taking into account the cost of the lamps. While calculating the real economy, we will consider that the life period of a power-saving lamp is 8 times longer, than the life period of a common glow lamp. For example, the cost of a common lamp is 1000 sums, and of the power-saving one – 6500 sums.

(1000-6500/8) х 10 + (183 084 - 36 616.8) = 1875 + 146 467.2 = **148 342.2 sums**

Totally, the overall economy from choosing the power-saving «AKFA Lighting» lamps is **148 342.2 sums**! Think about what you could spend this money on ?
