LED 11w 15w 20w E27 2u Feature: Durable and portable, easy to carry, lightweight 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. Specification: Material: Glass some electric element Light color: white Power: 11W-15W-20W Color temperature: 6400K Light head type: E27 Input voltage: 170-250V Frequency: 50-60Hz Size: 15.5 x 5cm Net weight: 55g Package Included: 1 x Light Bulb Note: please allow 1-5mm errors to the actual dimension due to manual measurement!
