LED Landing Light

Just Got and installed the par46 WAT G3! It’s bright! Was wondering about the voltage though, it say 14V, but my M20C says it’s a 12V system, is that a problem?

I noticed the unit Spruce sells states 10 degrees of horizontal and 10 degrees of vertical. The Amazon unit states 8 degrees? Does anyone know what an additional 2 degrees looks like? For the price difference does anyone really care? It seems the LED unit draws 2.6 amps. What does the old halogen bulb draw?

My old incandescent GE landing light drew enough amperage that turning it on and off was part of my Post-Engine Start checklist, to verify that the ammeter was working.

Now, I've had LED since April 2014, and it's only been turned off twice--once during annual and once halfway through pitot static test in my hangar, when he noticed it was on. It makes a great recognition light from the front, and goes on and off with the Master switch.

Airplane lesson….  Car lesson…. 101.

We call it a 12V system…. Nominally.

And generally… the voltage is most often over 12V…

Unless, it has been draining slowly for a while… like a month without flying…

But, when the alternator is charging it… zooom… 14V!

 

 

Sooooo…

There is always a bit of confusion to people new to the game…

 

Realistically Mooneys have two available voltage systems…

12V and 24V…

 

24V has become the standard of many vehicles… because the tons of wires become 1/2 tons of wires with the higher voltage…

PP thoughts only, not a mechanic…
