 Electrical - Landing Lights - Teledyne

Drop-in replacement for traditional incandescent lights. The Teledyne LED Alphabeam landing & taxi light will replace the following incandescent replacement lamps: 4313, 4509, 4587, 4591, 4594 & 4596. The ALPHABEAM™ LED Landing and Taxi Light, incorporating solid state technology, is designed for durability and long life. The ALPHABEAM™ offers an enhanced field of view compared with the incandescent models it replaces, and greatly improves visibility for night landing and taxi operations.

Is the ALPHABEAM™ FAA approved?
Yes, it is approved under FAA-PMA for most part 23 aircraft. See the Teledyne website for the list of approved aircraft

Can an owner/pilot install the ALPHABEAM™?
Yes, it is a direct replacement to the existing PAR 36 incandescent lamp. Minor maintenance may be performed by the owner/pilot, and does not require a certified mechanic.

What type of documentation is required for installation of the ALPAHBEAM™?
Installation of the ALPHABEAM™ requires only a logbook entry by the pilot/owner.

Does it matter how I hook up the wires or what voltage my airplane is?
No, the input of the ALPHABEAM™ is the same as an incandescent lamp. The ALPHABEAM™ is not polarity sensitive. The wires may be hooked up to either terminal. The ALPHABEAM™ operates on all 14 and 28 volt systems.

What is the projected life of the ALPHABEAM™?
The ALPHABEAM™ has a projected life of greater than 5000 hours of operation.

Can the ALPHABEAM™ overheat during operation?
No, the ALPHABEAM™ has built in thermal protection to reduce the current draw should overheating occur during operation. The ALPHABEAM™ must be installed in the original receptacle of the aircraft. If a rubber gasket was used, it must be discarded in this application to allow heat transfer to the airframe structure. This will guarantee good heat transfer and maximum performance when the aircraft is on the ground in a stationary mode of operation.

How much current does the ALPHABEAM™ draw?
It draws 1.6 AMPS @ 28 VDC as compared to 4.0 AMPS for the incandescent lamp @ 28 VDC and 3.3 AMPS @ 14 VDC as compared to 8 AMPS for the incandescent lamp @ 14 VDC.

What Environmental Testing has the ALPHABEAM™ been subjected to?
The ALPHABEAM™ has been subjected to 27 tests outlined in RTCA DO-160E, the industry standard required environmental tests for Airborne Equipment installed in aircraft. Contact Teledyne for more information on specific tests performed and qualification data.

Is the lens cover of the ALPHABEAM™ impact resistant?
Yes, it is made of a high quality, optical grade of Polycarbonate which reduces the risk of cracking induced by debris picked up from propeller wash.
