LED-based, the K132 has a long lamp life of 30,000 hours in Extreme Eco mode that reduces standby power consumption by up to 90 percent — from 5 watts to 0.5 watts. It also goes 20,000 hours in standard mode. LED lamps offer many benefits, including a longer lifespan with an always-available light source, instant on/off capability and better color saturation. With no breakable filaments or tubes, LED lamps are durable and reduce environmental impact, since there are no hazardous mercury or halogen gases.
