Feature:<br> Durable and portable, easy to carry, lightweight<br> Energy saving lamps, also called compact fluorescents lamp (CFL) or low energy bulbs, saves 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.<br> Specification:<br> Material: Glass some electric element<br> Light color: white<br> Power: 20W<br> Color temperature: 6400K<br> Light head type: E27<br> Input voltage: 170-250V<br> Frequency: 50-60Hz<br> Size: 15.5 x 5cm<br> Net weight: 55g<br> Package Included:<br> 1 x Light Bulb<br> Note: please allow 1-5mm errors to the actual dimension due to manual measurement! Thank you !<br> Real color may slightly different from pictures due to computer screen"s resolution, brightness, contrast etc.<br> If you have any question, please contact us before leave negative feedback, we will try our best to serve you, thank you for your understanding!<br> Specifications:<br> Durable and portable, easy to carry, lightweight<br> Energy saving lamps, also called compact fluorescents lamp (CFL) or low energy bulbs, saves 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.
