A high quality product. Easy installation, very bright LEDs, no bulb to burn out, and much lower power consumption. Unlikely this will need any further maintenance, ever! Great!

Awesome beacon! I installed on my Cessna 150G. So bright, I know I will not be missed for sure. almost to bright for night flying though, it flashes inside the cabin. But not to bad.

There are two things you can count on any Whelen products: they are good and extremely overpriced. Since our need to replace the old, broken and heavy coffee grinder was immediate, we pulled the trigger on this unit. Its very easy to install and you dont need to wait until its dark to appreciate its brightness. We can spot our both C-150s beacons on the ground all the way across the airport or anywhere in the pattern during broad daylight.

I replaced the rotating beacon on my 1957 182 with this light. It was a real easy install and it is a much brighter light. Well worth the cost.

Perfect fit to replace an original beacon on a 1967 Citabria 7KCAB. Much brighter than the original with a fraction of the amperage draw.

Q: What is the light output for the 2.6 in base 14 Volt red beacon - in lumens or candle power?

It is 100 candle power.

Q: What is the diameter of the larger base Whelen 360? Is it 3.75 or 3.67? The email ad says 3.67 while your online ordering says 3.75. My existing beacon is 3 5/8 or 3.67

The larger size is 3.75" per the technical drawings. We have updated the web page to reflect the correct size.

Q: I have a 1968 PA-32. Are these strobes self contained or do you need the Whelen strobe power supply that I currently have running the tail strobe. Also I have a Whelen self contained belly strobe (SA800EA?) that Id like to replace. Which models would work for the belly? What model would work for the tail?

They are self contained. As for the replacement we would need to know what is currently installed on the aircraft. SA800EA is an STC number that covers several lights.

Q: Is this a PMA part?

The Whelen Orion 360 series is FAA TSO approved for certified aircraft.

Q: Is this Whelen Orion 360 a rotating style LED or do they all flash at the same time?

They all flash at the same time.

Q: Will this beacon work on the top of the rudder of a C172N?

If the aircraft is 1967 through 1977 and has factory fin cap, then yes it will work. 1978 is the transition year from 12 to 28 volt, so you will need to verify voltage.

Q: Does the installation of the Orion 360 on a certified AC require a form 337, or does the FAA TSO allow it to be considered a minor alteration? PA28 161 181 etc. What does FAA TSO imply? 337 or simple logbook entry? I see no STC Documents for these lights.

The TSO should make it just a logbook entry/minor alteration.

Q: How often does this flash? I understand there is a synch cable to make other same beacons flash at the same time, but is there a way to guarantee that they flash at different intervals to aid visibility?

The flash rate of the 01-0772010-50 will be 45 +/- 4 flashes per minute. In regards to synchronization the LED beacon will flash at its own rate and will go in and out of phase with the remainder of the strobes as there is no means of syncing this product.

Q: Which Orion 360 beacon will work on my 1965 172F? My rotating beacon on the tail has died (motor)

Per Whelen: You would need to measure the diameter of the current beacon. It is likely either 3.75 or 2.6".

Q: what beacon replaces the grimes model 30-0437-100 belly strobe in a PA28-180?

14VDC Platform : OR36S1W Or 28 VDC Platform : OR36W2WL
