Light Emitting DiodesWe pioneered the use of LED optimized optics as well as custom electronic drivers for use in flashlights. The LED is the most significant innovation in portable lighting since the advent of the incandescent lamp. It is more efficient, less fragile, runs cooler, and has a 50-100 times improvement in life expectancy. The quality of light is quite different from that of an incandescent lamp. Like HID, it appears much whiter and shines farther underwater. Despite all of the positives there are also some challenges. Red and purple objects do not appear as vibrant under white LED light. Brightness decreases slightly as the LED heats up. Because power is limited to a few watts per LED, large arrays must be clustered to reach the illumination of a high wattage incandescent lamp.
