The one thing that you need to keep in mind about the LED's is that they put
out light in a very narrow cone- so for a landing light, maybe a 15 or 20
degree cone will be acceptable, but for other uses (position) it may not- I
was looking at making some LED position lights, but as I have come to find-
to get the required hemispherical coverage means about 20 or 30 for each
color on each side- still possible of course, but a lot more work......

A regular 55W Wagner automotive sealed beam halogen is 1000 lumens.
Cost....a few bucks.
The Luxeons are fabulous but pricey. For example a Luxeon Star is about 100
lumens and $40. (1000 lumens for $400).
The led landing light I envision would be 380 leds at 0.20 each or $76 plus
the printed circuit board ($24 maybe) and would be roughly equivalent to the
round 55W Wagner. MAYBE.

The wire in question is the +12v one that feeds the strobe power supply and
runs from the fuse block to the panel switch. From the switch another wire
goes directly to a screw-on terminal block below the seat and then on to the
power supply in the left wingtip. The power supply is grounded to the

Hi Dave and everyone
May I suggest, Dave, you go to the Aeroelectric Connection web site
www.aeroelectric.com and read it from stem to stern.
For everyone else, I'll suggest the statements made by Dave, below,
regarding Fast-On connectors are not supported by physics, or by current
industry practice. I am sure you'll find Fast-On connectors on current
production light airplanes by Cessna, Raytheon, etc.
Soldering connectors is highly process sensitive. A PIDG crimp in a proper
tool is not.
A screwed connection is a vibration-sensitive failure point, and increases
parts count. The more parts, the less reliable the overall system.
Dave wrote "Regardless of what anyone says, I like solder...". This is,
unfortunately, an emotional argument used as a final straw against any
logical rebuttal to a stated position. Any guy on this list who is married
knows the futility of trying to counter an emotional argument with a logical
one. A fellow has a right to any opinion he wants, and that's fine. NO ONE
has the right to pass on their emotionally-derived position as a basis for
engineering advice of any sort.
John, I'd say the advice you received below is worth exactly what you paid
for it. For everyone else, we all owe it to one another to provide solid,
factual information backed up by repeatable experiments and tests, not
hearsay and old wive's tales. The aeroelectric list on the Matronics list
server provides the some of the most solid, factual information on the net
for builders of experimental aircraft.
Some portion of John's wiring has a very high resistance, perhaps an
internal switch failure or some other problem. I'd suggest to John to
measure the resistance of the removed/discolored wiring/switch between the
fuse block and the power supply, and compare that to the replaced wiring and
switch. Let us know what you find.
This is not meant to be a flame, and if anyone is offended, I'm sorry. I am
also sorry to burden everyone with this excessive SIG, below, but when I
have to write an e-mail like this, sometimes it helps.

Dan, if you would forward this back to John, I'd appreciate it.
I would like to have his crimp tool, exemplar samples of any un-used
PIDG terminals in question, the overheated terminals still on "failed"
wires, overheated switch and fuseblock. I'd like to get to the
bottom of his problem but it will require some detailed analysis.
I'll replace any and all components he sends me with new ones.
If the tool is bad or not appropriate to the task, I'll make
him a hell-of-a-deal on a new one.
If there was but one joint involved, a missed opportunity
for adequate assembly is suspect. A series of similar failures,
suggests a broader cause . . .
Have him contact me directly if he's interested and we'll work
out details for the exchange. I'll publish findings here and
on the website.

Eric,
The only significant attraction of an "LED landing light" for me is - lower
current draw.
- Can you give an estimated current draw for the 55W sealed beam
halogen bulb and for the 380 LEDs and circuit board?
Life of a halogen vs LEDs is not a "tie breaker" - as halogen is so much
better than incandescant that I don't care for more life, given the low
price. The extra life of LEDs is beyond my lifespan so is no big selling
point.
- But, I want to go IFR at night on a 35amp alternator, with as no
"discharge" on the loadmeter/ammeter when I turn on the landing light at end
of the flight - or, if going to be drawing down the battery for 3 minutes,
then want as little "draw" on the battery as I can get.

In the halcyon days of the RB-36 the largest aerial recon camera ever built
took night photos from high altitude using the largest electronic flashtube
ever built. The bomb-bays were full of high voltage capacitors and power
supplies. Someone decided using a few really big magnesium flares was
better. So high technology is often not the better solution.

There are lots of solutions that would provide lower current draw that would
be very unsatisfactory.
>Can you give an estimated current draw for the 55W sealed beam >halogen
bulb and for the 380 LEDs and circuit board?
About the same. The leds, however are rapidly taking the lead. In a few
years there will be no contest at all. White leds are far less efficient
than the other colors. Weight is hardly an issue--A Wagner 55W lamp weigh 9
ounces. But it lasts 50 hours or so,
not 50 thousand hours.

Many builders want the reliability and extremely long lifetime of leds
(essentially permanent!). Leds also do very well in high-vibration
environments.

Thanks for the comment Dave.
A lot of what is happening in OBAM aircraft is not very scientific. There
are always tradeoffs, too. My technologic style is not "early-adopter". My
computer is usually 5 years old and I don't have a PDA or cellphone. But I
have replaced a lot of filament lamps in every sort of vehicle. And more
than once that burned-out rear white airplane tail-light has stopped an
otherwise enjoyable evening flight.
I don't believe an LED landing light is a must-have. But in several years it
will be the only reasonable choice. And filament lamps will be sold in
antique parts stores along with carburetors, breaker-point distributors,
relays and vacuum tubes. And that's okay.
Here's a bunch of good articles on the subject.

SigmaTek (who owns ARC) wants $125 for a copy. They generously knocked off 40%,
but even $75 seems a bit much for a manual that hasn't changed in the last 20

them on for a month or two and still be able to crank the engine. I left all
6 led lights on for 6 weeks hooked up to one of those small rechargable portable
battery jumpers used to jump start a car. They were still just as bright and
had about 1/4 of the charge left in the battery. The way I built them they
would fit in the inspection plate but if I ever wanted to remove them they are

The expected draw of a standard
100 W PAR incandescent landing light is about 9 amps
55 W halogen would be about 5 amps but may not have the same focused beam
density of photons
An LED lamp (hypothetical at this point, and still requiring improved
emitter efficiency) might draw 1-2 amps.

I'm not planning on offering any assembled beyond
the prototype which IS still available at $100.00.
You may purchase it if you wish.
I do offer boards for assembling the amplifier along
with detailed data package for assembly which is
presently downloadable from my website at:
http://216.55.140.222/temp/Audio_Prelim.pdf
Bare boards are $20 each and can be ordered
at

Bob (or anyone else):
Which Z drawing could I use for a Mazda rotary engine, single alternator, dual
battery application.
I'm helping a friend, who is building an RV9A, with his electrical system work.
Any and all comments welcome.
Thanks

Z-11 would get you started, Z-30 adds a second battery.

Hey Gabe,
That friend of yours building an RV-9 with a rotary wouldn't happen to
be Bernie Kerr would it? Can't be too many folks building an RV-9 and
sticking a rotary in it in South Florida.
I'm a friend of Bernie.

Looks like a great idea Dan. Just make sure to keep the lemons fresh.
I especially liked the photo record of the experiment. Makes understanding
the path of those little electron guys much easier.

| Subject: | SDK-1 dimmer kit for EL ??? |
--> AeroElectric-List message posted by: "Amit Dagan" <amitdagan@hotmail.com>
Q:
I have an automotive aftermarket electro-luminescense kit that plugs into
the 12v cigarette lighter socket, and you stick the 16" EL strips where ever
you like in your car (double sided sticky tape included).
Ofcourse I like the price (~$30 at GIJoes) for a panel light system, and I
will install this on the underside of the glare shield.
I was wondering, other than controlling the frequency in the EL converter,
if I used one of the dimmers in your sdk-1 kit,in series before the power
supply to the EL converter, would that dim the light ?
The EL kit takes 12v, 60milliAmps (0.72Watts).
Thanks,
Amit.

Hey Dan,
Looks OK with me, that is as long as one of them lemons is not the engine.
Just how much juice will the proposed rig put out?
I figure you'll likely end up in the pits though.
If it don't work? You could always an set up a lemon aid stand to help
recover the experimental development costs. :0) !
Now that's what I call mental, ER,.. I mean experimental.
Hot damn! that's the best laugh of the week!
Thanks Dan
