Featurebr Durable and portable, easy to carry, lightweightbr 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 Specificationbr Material Glass some electric elementbr Light color whitebr Power 20Wbr Color temperature 6400Kbr Light head type E27br Input voltage 170-250Vbr Frequency 50-60Hzbr Size 15.5 x 5cmbr Net weight 55gbr Package Includedbr 1 x Light Bulbbr 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 screens resolution, brightness, contrast etc.br If you have question, please before leave negative feedback, we will try our to serve you, thank you for your understandingbr Specificationsbr Durable and portable, easy to carry, lightweightbr 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.
