Lamp to decorative globe in glass opal; attack to E27 screw; power 23W in the version to Warm Light Extra/827 and in the version to Cold Light Extra/865 (Cool Daylight). They boast one long duration of life, par to 12.000 hours (10,000 hours for the versions to Cold light Extra/865 Cool Daylight). The integrated electronic circuit guarantees an immediate ignition lacking in sfarfallio. The luminous emission after a minute is equal to 70%. After 5.000 hours of operation the luminous flow is equal to 65% of the flow begins them, after 10.000 hours is of 50%. The variations of the mains voltage (10%) have a negligible effect (<5%) on the luminous flow. The tension of demanded minimal feeding for the ignition and the operation is of 180 V. Consistent to norms IEC968 (emergency), IEC 969 (performances) and to directives CE.
