The MASTER TL-D Eco lamp offers the same light output as a MASTER TL-D Super 80 lamp, while using less energy, thanks to the use of specific phosphors and a special gas filling. Application areas are schools, offices, governmental buildings and healthcare environments. Simple lamp-for-lamp replacement for more than 10% energy savings Makes lighting installations compliant with latest indoor lighting standards Relatively high efficacy, both initially and during lifetime, with high lumen maintenance. The only T8 fluorescent lamp that saves more than 10% of energy in existing luminaires with electromagnetic gear Lower power savings with electronic gear depending on type of gear (current- or power-controlled) Can be directly retrofitted into existing fluorescent fittings operating on electromagnetic or electronic gear in indoor applications Uses the latest highly efficient phosphors and special filling gas High-quality lighting with good color rendering (CRI>80) Light output comparable to other TL-D Super 80 colors Lumen maintenance and lifetime the same as other TL-D Super 80 colors Dimmable. For use in indoor applications with room temperatures above 20 °C (which implies temperature around the lamp of over 25-35 °C) Primary focus on offices, schools and hospitals; secondary focus on retail, industry, supermarkets Not recommended under the following conditions: - with air flow around the lamps - in luminaires with active air handling (lamp temperature will not be the required 25-35 °C, but room temperature) - in open luminaires/battens very close to air conditioning outlets or cold air flows - in space above freezers (temperature may easily drop below 20 °C) - in combination with VRUs (voltage reduction units). .
