Make sure you drill the hole in the bottom of the strobe if it is to be mounted on the bottom of aircraft. I made the mistake of not drilling and had to buy a new one due to water collecting in the unit.

Whelen lighting products are good quality but grossly overpriced. And in the last 2 or 3 years the prices of many of their things like LED beacons have increased 30% or more.

Q: When installing the A450 light assembly what adapter do I require? I am replacing a Whelen Model 70509,

The H102 adapter is used for flush mounting, and the H103 is used for mounting in a standard 3-3/4" rotating beacon hole.

Q: Does this kit come with the curled strobe tube bulb or is this a different type of strobe bulb? My current install that I need to replace has a curled strobe tube.

Yes, this model A470A includes the curly bulb type. If you keyword search A470, the first result will be a parts breakdown which will show you the bulb you will receive.

Q: We are looking for the power supply for the Whelen A470A series. Is there a specific power supply that will work for this unit?

Per the manufacturer, no, this unit is capable of running off of most power supplies. There is no one specific power supply for it. For example, WHELEN HDACF POWER SUPPLY (part # 11-16218) would work fine.

Q: Is the Whelen A450 light FAA-PMA or STC approved?

Yes, this is PMA approved.

Q: Does the A470ADS Whelen strobe require a separate power pack or can it be wired direct to the 12 v aircraft bus bar?

It would require a power supply.

Q: Does the flash tube assembly come with the AMP connector already attached or does it need to be purchased separately?

This part comes with the amp connector installed.
