Aviation-bulb-instrument-28v-25ma

am offering you an American light bulb intended for use in aviation.

The bulb has a nominal voltage of 28V and has undergone a special aging and testing cycle to ensure that it has a guaranteed operating time of 5,000 hours.

Bulbs of this type are used in the lighting of aircraft instruments, as well as in illuminated buttons confirming that the systems are turned on.

Such buttons are used in BOEING planes and other aircraft.

They usually contain 2 or 3 such bulbs.

The diameter of the bulb holder is 4 mm.

The total length of the bulb is 8.5 mm.

Nominal operating voltage 28V

Nominal current 25mA

The bulbs were manufactured to military order and are of very good quality. They have passed all the tests needed to work in aviation.

ATTENTION!

The offered bulb with an adapter (orifice) is a perfect replacement for the popular SM28 aviation bulb, as it has a much longer lifespan.
