Does the polarity of the wires matter during installation?
Does it matter what voltage my aircraft or rotorcraft is?
How much power does the ALPHABEAM® II consume?
What is the projected life of the ALPHABEAM® II?
Is the brightness of the ALPHABEAM® II same as the incandescent bulbs it replaces?
Can the ALPHABEAM® II overheat during operation?
Does the Intelligent Anti-Icing feature on ALPHABEAM® II automatically turn on?
What Environmental Testing has the ALPHABEAM® II been subjected to?

Is the ALPHABEAM® II FAA approved?
Yes, it is approved under FAA-PMA for many Part 25, Part 27 and Part 29 aircraft and rotorcraft models. See the Teledyne website for the list of approved aircraft and part numbers. Models with FAA-PMA are listed on FAA-PMA Supplement download. Teledyne updates the list with new models several times per year. Contact Teledyne for questions on your model aircraft or rotorcraft if it is not listed on the PMA Supplement.


Are modifications or special installation instructions required for the ALPHABEAM® II?
No modifications to the aircraft are required for installation. The ALPHABEAM®II is the same footprint as a PAR 46 incandescent or halogen bulb, with screw terminals that are not sensitive to polarity. It is a drop-in replacement.
The rubber gasket typically used with incandescent can also be used with the ALPHABEAM® II, or the rubber gasket can be removed.


What type of documentation is required for installation of the ALPAHBEAM® II?
An Installation notation in a maintenance log.


Does the polarity of the wires matter during installation?
No, the input of the ALPHABEAM®II is the same as an incandescent lamp. The ALPHABEAM®II is not polarity sensitive. The wires may be hooked up to either terminal.


Does it matter what voltage my aircraft or rotorcraft is?
Yes, the ALPHABEAM® II will operate only on 28 VDC and 28 VAC, 400Hz systems.


How much power does the ALPHABEAM® II consume?
For 28 VDC aircraft the power consumption is 70 Watts (typ.) during normal operation.
When the Active Anti-Icing system is activated at below 0C, power consumption increases 30-40 Watts, and returns to 70 Watts once temperature returns to above freezing.


What is the projected life of the ALPHABEAM® II?
The ALPHABEAM® II has a projected life of greater than 30,000 hours of continuous ON operation.


Is the brightness of the ALPHABEAM® II same as the incandescent bulbs it replaces?
Yes, The ALPHABEAM® II has approximately 5600 lumens inside the 10 beam angle, and meets or exceeds the brightness of the incandescent or halogen lamps it is certified to replace.


Can the ALPHABEAM® II overheat during operation?
No, the ALPHABEAM® II has built in thermal protection to reduce the current draw should overheating occur during operation. The ALPHABEAM® II must be installed in the original receptacle of the aircraft.

The ALPHABEAM® LED Taxi / Landing light is equipped with a thermal fold-back feature in the circuitry, designed to prevent overheating and premature failure of the light. This feature engages only when the ALPHABEAM® is operating in an environment where sufficient heatsinking to dissipate the heat emitted from the back of the device is not available, such as use in a laboratory environment. Should the ALPHABEAM® reach a case temperature of 85C without proper installation, the current to the LEDs is reduced to prevent overheating and possible premature failure. This reduction in current reduces the overall brightness of the LEDs during the overheating condition only. The brightness levels as indicated on the datasheet will resume to full brightness once the case reaches normal temperature.


Does the Intelligent Anti-Icing feature on ALPHABEAM® II automatically turn on?
Yes, when the glass temperature reaches 0C or below, the Anti-Icing system will automatically activate to prevent icing of the lens.


What Environmental Testing has the ALPHABEAM® II been subjected to?
The ALPHABEAM® II has been subjected to all applicable in RTCA DO-160G, 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® II impact resistant?
The outer lens cover on the ALPHABEAM® II is made with durable high impact resistance glass, designed to withstand moderate FOD particles on the runway and harsh chemicals associated with aircraft maintenance and cleaning. If the outer lens on an ALPHABEAM® II breaks or cracks, contact Teledyne for questions on repair.
