Need help figuring out the voltage on aircraft runway lights.

[Ramson222]

I recently bought a shopping bag sized grab bag of military vehicle small parts for $5.
Two of these led lights were in the bottom of the bag. Can anyone help me ID them and the correct voltage. I have spent over a hour trying to figure out what the are with the help of google and have had no luck. Thanks260426

Mmm. I only worked on runway lighting once, and it was many years ago. But if I recall correctly they 4,200 volts. AC of course. The reason for the hi voltage was the very long runs of wire. As the wire gets longer the voltage at the far end gets smaller. These were at SeaTac which at the time was about 20,000 feet.

Good luck.

Maybe check with the FAA?

[Petrol & Powder]

The label identifies it as a Crouse-Hinds (now owned by Eaton) device.
The FAA Specification "AC 150/5345" returns as the standards listed by the FAA for Obstruction Lighting.

Need more information about the device, Is it an LED?, incandescent, strobe, etc.

[Petrol & Powder]

And BTW, Crouse-Hinds made electrical equipment such as breakers, panels, bus bars, etc. but they are probably best known for traffic control equipment such as traffic lights and related control boxes, so I might suspect that 120 volt 60 Hz AC may be used for obstruction lights simply because it is readily available.

Bought some property years ago with a helicopter hangar and landing pad on it. I know the lights have a small transformer inside I assumed to drop 120V to 12V, but now I remember there is also a large transformer at the pad. Next trip outside I'll see if the nameplate is still legible.

[psychodad]

I lied. What I thought was a transformer isn't. Found some literature which indicates 240/120 VAC. My stuff was made by Downing Electronics in the '80's. Sorry, I'm not much help.

Definitely more info required...FAA AC 150/5345 is the general classification for advisory circulars for all airport lighting and each specific type...i.e.runway, taxiway, obstruction, rotating beacon, etc...has it's own identification; example: AC 150/5345-43J covers obstruction lighting, AC 150/5345-53D covers procedures for certification, and so on.

Many, many years ago, I worked in Base Maintenance at the old Chanute AFB (as a civilian) and seem to recall that the runway/taxiway lighting was a high-voltage/high-frequency system...something like 4.4Kv and 400-cycle. We blew a transformer once and the replacement had to be scrounged from a closed-down training base somewhere in Kansas.

Not enough information from the OP.

[Ramson222]

Only other bit of information I have is that they are led bulbs.

[Ramson222]

Guess I will have to experiment with them.

[popper]

Probably 120ac as no sticker indicating over 150 volts.

[Petrol & Powder]

Does it have an internal power supply? Is there a complete part number on another light? What do the terminals look like? Can you take a picture of the other sides? What color is the lens? ...........

[Lloyd Smale]

if there leds id guess there 120. We tore down some runway lighting at an decommissioned air force base when I was a lineman. They were sodium bulbs though and if I remember right they were fed with 480 volt. I don't recall if they had internal transformers though. We just took them down and tossed them in the back of a dump truck.

Here's the instruction manual.

I couldn't find the voltage. LOL

[Petrol & Powder]

How did we determine that was the same light the OP has?

[shaune509]

If I'm reading the pdf right on the last page it shows models using between 12 and 50 VA. The ones with heaters are rated at the higher end.

A volt amp is basically a Watt. No closer. LOL
