Decoration E27 Led home light bulb 2.0W and 150Lm brightness. Bulb type G45, light color Green The bulb is capable of replacing the 12W old filament lamp. Filament diodes with a gentle electrodes. The energy efficiency of light bulbs is expressed in lm / W. There are currently a number of different bulbs with different efficiencies. Energy-efficient LED bulbs are on average 5 to 10 times more efficient than a filament lamp. Consequently, LED bulbs reduce energy consumption and costs by 50-90% compared to a standard lighting solution.
