In lighting terms, "Lumens" or "lm" is the measure of brightness. Where as, the measure of electrical consumption is "Watts" or "W".
LEDs have the highest Lumen-to-Watt ratio as compared to any other light source. Thus, consuming less electrical power and flashing a brighter beam of light.

Also, LEDs have more than twice the life of an average CFL bulb and 15 times the lifespan of a conventional GLS Light Bulb. Thus, the higher price you pay for an LED light, lasts you longer and saves you more than 50% on your electricity bill when compared to CFL, and 85% as compared to Ordinary GLS Bulb. Which, in the long run, would be much easier on your pocket compared to changing electricity hungry bulbs every now and then,

LED | CFL | Ordinary Bulb | |

Life (hrs.) | 15,000 | 6,000 | 1,000 |

Lumens | High | Lower | Lowest |

Fragile | Sturdy | Fragile | Very Fragile |

Hazardous Material | None | Mercury | None |

Heat | Medium | Medium | Highest |

Switching Rate | Fast | Slight Delay | Fast |

For testing purposes, we compared the costs of using a LED and CFL for the exactly same scenario,

CFL | LED | |

Wattage | 14 | 9 |

Brightness (Lumens) | 720 | 810 |

Life (hrs.) | 6000 | 15000 |

No. of Bulbs used (15000 hrs) | 3 | 1 |

Cost per Bulb | Rs. 170 | Rs. 585 |

Total Cost of Bulbs |
Rs. 510 |
Rs. 585 |

Units of Electricity Consumed | 210 | 135 |

Cost per unit (assumed) | Rs. 8 | Rs. 8 |

Electricity Cost | Rs. 1680 | Rs. 1080 |

Power Factor* | 0.5 | >0.9 |

Total Electricity Cost |
Rs. 3360 |
Rs. 1200 |

Total Cost | Rs. 3870 | Rs. 1785 |

Thus, Tintech LED is cheaper by Rs. 2085/- per lamp when compared to a CFL Lamp.

* - In AC circuits, the Power Factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power factor can get values in the range from 0 to 1. When all the power is appropriately being used, the power factor is 1. Similarly, when all the power is reactive power with no real power (usually inductive load) - the powerfactor is 0.
