Particularly high luminous efficacy: LED tube SubstiTUBE G13 T8 EM Ultra Output, 29 W, 6,500 KThe LED tube lamp SubstiTUBE G13 T8 EM Ultra Output serves as a retrofit replacement for existing T8 lamps in CCG luminaires. It is therefore operated with electromagnetic ballasts. It can also be used at low temperatures of up to minus 20 degrees. It has a particularly high luminous efficacy. The average service life (30,000 hours) and the particularly good switching stability (200,000 switching operations) are additional features.Technical features:- Daylight white light colour: 6,500 K- Luminous flux: 3.500 lm- Comparative value: 58 watts- Type of current: alternating current (AC)- Supply voltage: 220 - 240 V- Suitable for DC operation- Input voltage DC: 186 - 260 V- Operating frequency: 50/60 Hz- Temperature range: -20 to 45 °C- Low flicker according to EU 2019/2020 (SVM ≤0.4 / PstLM ≤ 1)Special features:- Simple and fast replacement of conventional T8 lamps- Compatible with electromagnetic ballasts- Average life: 30.000 hours- very good switching resistance (200,000 switching operations)- very high luminous efficacy: 120 lm/W
