LED lamp (candle) 4W LED

Lamp light-emitting diode (LED candle), rated power 4W, E14 socle, color temperature 3000k, metal case of color gold, sizes: diameter is 39 mm, height is 155 mm. NOVELTY. A light-emitting diode or the light-emitting diode — the semiconductor device with electron-hole transition creating optical radiation at a transmission through it electric current in the direct direction. The characteristic of LED technology allows to estimate reliability of the offered goods: 1. Operation duration: service life of light-emitting diodes much more exceeds service life of all other light sources, it makes more than from 50000 to 100000 hours. 2. Energy economy: in comparison with luminescent, they consume 60% less electric power. 3. Ecological safety: there is no mercury. 4. High reliability: quality of light-emitting diodes is provided with the high durability and reliability of elements of which they consist. 5. Low operational costs: at the expense of the long term of operation, costs of replacement of lamps decrease. 6. High quality of lighting: the illumination created by LED lamps has high degree of contrast. 7. Lack of stroboscopic effect: in light-emitting diodes is absent low-frequency pulsations, harmful to eyes, which cause so-called stroboscopic effect. 8. Low load of power supply networks: when using light-emitting diodes the possibility of an overload of municipal and city networks at approach of twilight when a large number of lamps in large quantities joins is excluded. 9. Possibility of brightness control of lighting
