E27 Led home light bulb 12W and 1050Lm brightness. The brightness of the light corresponds to a 100W bulb. Light irradiance 270 degrees. Decorative glass design. The bulb type is G120. Led bulb is energy saving A ++. 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.
