MEGAMAN® LEDs and CFLs are designed to help you conserve energy and save money, which in turns reduces CO2 emission. Let's see how much energy and money can be saved and CO2 can be reduced when switching to MEGAMAN®.

Total Cost of Ownership (TCO) after 15,000 hours
Lamp Type: MEGAMAN® CFL GU10 Halogen GU10
Wattage(W): 11 50
Average Lamp Life (h): 15,000 2,000
Relamping interval: Every 15,000 h Every 2,000 h
Lamp Cost after 15000 h: HK$128 HK$10
Energy Cost after 15000 h: HK$165 HK$750
Total Cost: HK$293 HK$760

Total Savings = HK$467
Amount of CO2 reduced after 15,000 hours = 403.7Kg

Calculation Formulas:
Energy Cost = Wattage x Quantity of Lamp x Operating Hours x Electricity Cost
Total Cost = Total Lamp Cost + Energy Cost

Assumptions:
Electricity cost = HK$1 kWh
1kWh = 0.69kg of CO2 emission

Calculate Your Savings

Conventional incandescent bulbs waste 90 percent of their energy in generating heat when lit. Replacing them with energy saving lamps can lower the electrical bill for lighting up to 80%. See how much you can save if you switch to energy saving lamps.
