Each incandescent position light bulb on an airplane draws about 2 amps each on a 14VDC power system. If you have two forward (red and green) and one rear (white) position light on your plane, that is a 6 amp draw or 84 Watts of power.
By comparison, AeroLEDs position lights draw about 6 Watts for each position (red, green, white) for a total of 18 Watts or 1.28 amps on a 14VDC power system.
Thus, converting to AeroLEDs LED lights will save 66 Watts of power and reduce the electrical load by about 4.7 amps for the position lights over traditional incandescent lighting. LEDs far outlast incandescent bulbs, so in addition to saving power, they provide a maintenance free lighting solution for aircraft.
The AeroLEDs Pulsar NSP, NS180, and Suntail lights have recently receive TSO approval from the FAA. If you are interested in upgrading your lighting on your certified airplane, contact Susan Calvin at susan@aeroLEDs.com for more information on our TSO'd lights.
