Crompton CLL40SW Compact Fluorescent Lamp Single Turn L Type (PLL) 2G11 4 Pin 3500K White - 40 Wat...Crompton CLL40SW Compact Fluorescent Lamp Single Turn L Type (PLL) 2G11 4 Pin 3500K White - 40 Watt. 4 pin 2G11 Socket; 3500K White. Energy saving lamps also called compact fluorescents lamp (CFL) or low energy bulbs, save energy by using the same technology as a fluorescent tube to generate equivalent light outputs to a conventional tungsten filament bulb but with a significantly lower power requirement. Due to the technology used they also offer huge increases in life expectancy over conventional lamps. The marked wattage of all energy saving lamps is much lower than the equivalent conventional bulb, therefore, costing less per hour.
