1. The cap is made with powder-coated 6063 aluminum, which brings up smooth surface, portable structure and heat-resistance. 2. Lampshade is made of toughened glass, which assures good transparency and intensity. 3. It can be customized to different power capability, luminance and light angle. 4. safe, energy-saving and environment-friendly: The lamp cap decreases wind resistance and lamppostí»s burden because its light and thin, besides the cap avoids traditional lampí»s smash problem because it is resistant to shock, anti-seismic well and have no filament or glass shell. To reach the same illumination, LED lamp saves 60% energy compared with sodium one. The cap excludes pollutive elements: plumbum, mercury. 5. technical data: Power: 15W ¿C 35W Power Factor: 0.9-1 Luminous Efficiency: >100lm/w Light Attenuation: 85 Illumination Angle: 140 degree (can be customized different angles) Work Life: >50000 hours Material for Light Body and Shade: Aluminum Alloy & resin Protection Grade: IP65 .
