At LEDtronics we pride ourselves on being known as the world's leading supplier of innovative direct incandescent replacement LED Bulbs, lamps, clusters and arrays. As you are aware, energy conservation and lowered electrical costs have become a way of life in the 21st century. Our rugged LED's last 100,000 hours, over ten years, which greatly reduces maintenance and replacement costs because LEDs are virtually immune to shock and vibration. Our LED bulbs use a fraction of the electricity (LED lamps use 80% to 90% less energy then the incandescent lamps they replace) necessary to light an incandescent bulb; they significantly reduce power consumption to help achieve energy conservation goals. LED bulbs also remain cool so there is no excessive heat buildup, which can influence building air conditioning costs.
