View Full Version : LED lighting
07-01-2009, 10:02 AM
I now have Halogen lighting for my marker/navigation lights and my landing lights. They pull a total of 39.6 amps when lit. I've ordered replacements for these in Gen 3 LED's now only going to pull 2.2 amps.:whoo:

I would like to do that also.
With our electric pre-rotators alot of stop-and-go drains my battery WAY down. So I don't turn on my strobes and running lights until my battery is re-charged.
I would like to have them on all the time.

Brent, Could you post your vender and part numbers?
Thanks, John K.

Brent, does that 2.2 amps include a landing light, strobe and position lights combined?
There are some LED systems out there that do not meet the standards of FAA Advisory Circular 20-74 (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/0410ab09b4a7057d862569ae006d35d1/$FILE/AC20-74.pdf), which specifies brightness, color temperature (what exact shade of red and green), and directionality expected of aircraft lighting.
I pressed one manufacturer in particular, we'll call him "Brand K," about whether his products met this FAA standard, and he danced. Short answer between the lines was, "no."
The FAR are somewhat vague about exact specs on brightness, and an "advisory" circular is just that, but it is the standard.

I was reading a PPC forum and came across this for new very bright LED lights:

Tim Verroi bought some of Bear Perkins LED stobes at Bensen Days. Maybe he'll chime in and let us know how they've been doing and how visible they actually are.

I bought 3 of Bear Perkins strobes at Bensen Days. They are going on my heli. By the way,,,Bear is going to be have his stuff at Mentone.

I talked to Bear about his LED light at BD also and for 50.00 each it not a bad price. I told him I would be contacting him.

You may be interested in what I am thinking about putting on mine.
It's the pair of halogens that WalMart sells - the smallest of their line, black and square shaped, with real glass lenses (cheap).
I removed the H3, VERY high amp draw bulbs, and going to try the SMD LEDs in their place - a simple R/R. The LEDs can't match the brightness of the halogens but the amp draw is a fraction of what the H3s are.
I'll show you this weekend if you're interested.
See you then..........

Here is the lights I'm using from Aircraft Spruce

Thank you Brent! That looks like an easy upgrade!

Any time Tim. They shipped the landings lights in 2 days. Spruce tells me 2 weeks.

Does that matter? These are, after all, "Experimental" aircraft.

From what I'm told, it depends on the guy who does your inspection. It would be tough to measure lumens and color temperature precisely during an airworthiness inspection, but pretty easy to test the directionality.
The red and green lights are supposed to be invisible in a 140º arc behind the aircraft, where only the anti-collision lights should be visible. This would be easy to test with a walk-around.
When it comes down to it, if the inspector isn't comfortable with your choice of lights, I believe he has the leeway to issue operating limitations for day/VFR only. Fortunately, the prices on LED systems that make spec are gradually coming down.

This is an informative post.
Expermental or not, there are specific requirements that must be met to meet the faa standards for aircraft lighting.
This link shows a great graphic of the requirements. There are variations for rotary wing aircraft, but generally, this is a great place to start:

Our M24 was equipped with AeroLeds from Aircraft Spruce. Total elec-consumption dropped drastically so no worry on the battery anymore.
Another advantage: LEDs can be attcehd directly w/o any extra electronic box. That spares also much weight.

could u not just use 1 of them 9v square batteries?
i remember seeing a few of them rc lighting kits which used a 9v battery.
they looked good and did the job unless you put thenm on a offroad car

Omg thats cheap for being LED. Cheapest I found was about 1000. Is that one better than a LCD IPS like Dell Ultrasharp 22"?

Did you see these ?
