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.

This landing light is WAY better than a standard glass bulb light. I installed the light my self in about 10 minutes. Flew out to KHII, and could see the desert below me at about 500 ft AGL on my approach. The light is very nice & white, not the usual dingy yellow tone of a filament style bulb. Worth every penny - I would by another in a second! |

If you're debating between the Whelen Parmetheus and the Alphabeam, do yourself a favor and go with the Alphabeam. It's much brighter (especially on 14V systems) and one part number covers all applications. Long life, low power draw and bright white light! Well worth the price. |

Light output is hands above old bulb but by NO MEANS is this a drop-in replacement in a PA-28-140. Required cowl modification to make the bulb fit. |

Did not fit my 79 pa-32 300. The light stood too proud and the retaining ring would fit back on. At least a 1/4 inch of fiberglass would have to be sanded/filed off from the edge around the hole to allow the light to fit. |

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.
I just purchased the Alpha beam because this Q&A said I could replace my sealed beam myself w/o having an A&P do it. But AOPA says because it is not an in-kind party (sealed beam) then I must have an A&P install it even if it's a PMA part. Who is correct please?
Per the manufacturer, our light is a direct replacement for a sealed beam light. FAR Part 43 Maintenance / Preventative Maintenance states that a certificated pilot under Part 61 may replace any bulb including the landing light. Since our lamp is a direct replacement, a pilot may change the bulb without assistance from a certificated A&P mechanic.
Can the ALPHABEAM lights be used with a pulse control system?
It depends on which pulse control system is being used. Teledyne has not tested all the pulsing systems available on the market. However, a good rule of thumb, the newer ones (on the market for 2 years or less) are generally designed to accommodate LED lighting. The older pulsing systems may not accommodate LED technology. We recommend contacting the pulsing system manufacturer to verify it will work.
What is the warranty on the Alphabeam LED Landing and Taxi Light?
This product has a one year warranty.
