High Lumen output per watt, 8-90LM/Watt, provides high energy savings. Omnidirectional LED bulbs, allowing for 270°light spread. LED drives for our LED bulbs are all with IC solution. Most of the electricity in an LED becomes heat rather than light (about 70% heat and 30% light) if this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Our LED bulbs have excellent cooling with aluminum die casting heat sinks. Aluminum PCB with high thermal conductivity and excellent heat dissipation. Time-efficiency: Our LED Bulbs can last up to 50,000 hou
