Bishop Aviation, a pioneer in internally lighted instrument technology, has expanded to include manufacturing of LED (Light Emitting Diode) lighting for aircraft instrumentation. More energy-efficient than incandescent and fluorescent bulbs, LED lights have the advantage of a longer working life, expanding the life of the product by 4-5 times. LED lighting emits no heat; this “cool-to-the-touch” technology represents an advantage over incandescent bulbs that can cause instrumentation panel lenses to crack over time due to heat emissions of 200 degrees.
LED technology adds a life expectancy of 50,000 hours to the lighting component. LED lighting, while producing a whiter light, uses less electricity -- about 1/5 of the electricity used by standard incandescent bulbs.
