Very energy efficient professional energy saving lamp with 4 copper pins. For use with conventional ballast. These Dulux T/E energy saving lamps use a GX24Q lamp base. The light output at 25°C is 68 - 72 Lumen/watt. Osram's DULUX T therefore provides a lot of high-quality light for a low wattage, which makes this lamp a widely used lamp for offices, portals and outdoor lighting. The DULUX T/E is dimmable and can be easily replaced by pulling it out of the fitting. Lifespan: Average lifespan of DULUX T/E is 36,000 hours. Available: in the lamp colors 827 (warm white), 830 (white), 840 (bright white) and in the wattages 13W, 18W and 26W. The color rendering is >80. Alternative: Osram DULUX T/E is possibly interchangeable with the Philips Master PL-T 4 pin lamp.
