Author: Alan Wallace <o22rv7a@...> Time: Sun Nov 27, 2005 2:53 am PST Link

I need to order the lighting pkg to include the landing light system. Can any of you give me some info on the following ?

Where is the best place to buy the Whelen system ? I have decided on the system that has the strobes and the position lights in one system.

What is the best way to do the landing lights ? I like the concept of the lights being located in the same area in the wing tips as the strobe/position lights, (if it will all fit).

Van's shows a dual lamp landing light system in there catalog that mounts in the wing tip, will it fit with the strobe lights ? Anyone used the system from Van's ?

I need as much landing light as I can get when landing at Columbia Airport, (O22) in the foothills at night.

Alan,

You might want to consider a strobe package from Creativair. You'll save a
chunk of cash and lose no functionality (to the best of my knowledge).

A few months ago my Whelen CF power supply died after about 600 hours. I
sent it back to Whelen for warranty repair, but in the meantime (didn't want
to wait) I "upgraded" to the AVI-PAK power supply from Creativair. It is
less expensive, has more features, and puts out more energy. When I got my
Whelen p/supply back I sold it to another builder.

If I were doing it over again I'd just go with the AVI-PAK from the get-go.
Just my 2 cents.

http://www.creativair.com

Landing lights -- I'd use the Duckworks system again in a heartbeat. I
still believe it provides better runway and taxiway illumination than other
options.

To lend credibility to these statements (I hope), I have 46.1 night hours in
my plane with 97 night landings.

I agree with Dan. I have the Creative Air LED position lights. I have not
flown with them but when demonstrated in my dark hangar the comment is
usually, "holy sh!t." I have never built anything electrical and built the
lights in just under 3 hours. They require no special power requirements.

I also went with the Aeroflash strobes. They have individual power supplies
which probably adds a pound or two but the dependability factor was reported
to be much higher in my early research. (may be product by those reporting).
They were also around $400 for the complete set up. Remote power supplies
made wiring easy.

Also have the Duckworks set up with one set a little lower than the other.
Didn't do the wig wag but might add that later.

Thanks Dan & Larry,

I have read all the threads you referred me to Larry and have checked out the websites for both CreativAir and Duckworks that you wrote about Dan, thanks to your help I have a much better understanding of whats available, I like the Led style strobes.

What do you think about putting one duckworks landing light in one wing and using the led landing light combo in the wingtips as well. This would give me lots of light for the edges as well as the center of the runway/taxiway. The wingtip landing lights could be put on the Wig-Wag Flasher that CreativeAir sells.

What ever floats your boat! Sounds like that might be a good combintion. I used two Duckworks and will probably use the LED's for position lights, if for no other reason than LED's are almost bullit proof.

<SNIP>I have the Creative Air LED position lights.<SNIP>

For those who like to thinker, SUNBRITE makes high intensity LED
incandescent replacement lights for 1156, 1157, and 3157 automotive
sockets. Those are DOT approved, meaning they are bright suckers for
day light use in brake and turn signals.

I priced 2 RED, 2 GREEN and 1 WHITE for less than $50 bucks. Nice
thing is they use standard autmotive sockets available at oyur local
boneyard and need no electronics behind them other than a 12V supply.

I will be ordering 2 RED ones to experiment a little and see what the
reults are. I am not concerned with brigthness as much as angle of
view.

Jose, I have been experimenting with LEDs for my plane
as well. I found some online for 10 bucks each. I
bought a red, green and white to play with. They are
very bright, and I believe will do the job nicely.
They have 25 LEDs, 20 on the ends, and five around the
outside of the base. If anyone is interested I can add
a link to the site from my computer at home.(dont have
it saved here at work)

I'm using Duck Works in both wings for landing/taxi & will probably convert those to HID for intensity gain & reduced power consumption. I will be installing wig/wags in the wing tips and like the simplicity of using LED. Those white 1156 base Sunbrite units look like the ticket. I suppose that it would also make sense to replace the incandescent position lights with LED as well. Any comments??

Is there an LED alternative for the landing / taxi lights. Something
mounted close in near the pitot might give as good a reflection off the
runway as the 75w bulbs mounted on the wingtips. Those ducks are nice but
$$$.

<SNIP>I suppose that it would also make sense to replace the
incandescent position lights with LED as well.
Any comments??<SNIP>

I many times comment that the best choices are made not on your first
build but your second or third, when you get to apply what you learnt
from the previous endeavor.

I made the decision to spend $$$ on my second airplane by installing
the Whealn wing tip NAV/POS/STORE unit. Ouch! I fly little at night
and even if I did, the NAV/POS/STROBE lights are not going to make a
heck of a lot of difference.

This time, I am going to install equipment that makes the airplane
legal but saves mega dough in the process. I am sure it will draw
comments from the purists but to me it's just a light. I ordered two
Sunbrite 1157 RED ones and two 1156 GREEN ones to install in the
wingtip. If it works, the whole thing will run me $35, now couple
that with the $30 landing lights and you get the picture. All I need
is a couple of strobes and I will be good to go.

The way I look at it (i.e., my philosophy) is that a penny saved
whether it is on lights, a heated pitot, electric trim, an A/P, or a
fuel valve goes towards a (Gulp!) Dynon. At least it would get more
use and make the airplane almost all glass with the EIS and Dynon.
Sorry, I like the ASI in steam gauge mode, so no digital one for me.

Here's the way my wingtips are shaping up. I'll post a pic when I
get to play with the LED lights. Since I keep my plane at home, I
will be able to quickly compare the quality of light from the real
deal to the home made deal.

I gotta ask - what is that foam looking stuff inside
your wing tip?

The skins on the wingtips are thin and flex too much. The foam gives
them rigidity and adds very little weight.

Some folks use fiberglass and home-made ribs made of wood or aluminum
to stiffen things up but that takes a lot of time to fabricate and
adds a lot of weight (resin is heavy).

The foam is insulating foam. I bought that on clearance a while back
and gave them a try since all they were doing was collecting dust.
The results are great. The tips are stiff enough to take a lot of
pressure and yet maintain a good degree of flexibility if they were
to be bumped hard.

If I were to do it again I would use the original foam brand which I
believe is called "Great Stuff" as it expands even more than the
stuff I got.

Has anyone tested these LEDs with a light meter to verify they meet
FAA specs?

>>> Has anyone tested these LEDs with a light meter to verify they

Good question. I did some looking into it a while back and found the
DOT approved lights hade plenty of juice measured in Candlelights
(Cd).

Each Sunbrite bulb I bought has 47 Cd on Red and about 75 Cd on Green
at a 30 degree viewing angle, which far exceeds the 40 Cd required
by the FAR.

The FARs require 110 degree coverage. By having multiple LED light
assemblies (2 or 3 in my case) this can be easily achieved as shown
in my first arrangement on the link below

http://www.hometown.aol.com/pepeborja/Led2.jpg

Note that in my original wingtip prototype I only use 2 lamps. The
forward looking LED exceeds the 0-10 degree and 10-20 degree
requirement by providing 47Cd coverage on the front (oncoming)
plane.

Notice from the FAR that from 20-110 degrees only 5 Cd are needed.
That's handled partially by the forward looking LED and the one
mounted sideways. Since the lights are cheap and weight next to
nothing, I will add another light where the wingtip planes inside the
wingtip intersect (above the forward looking lamp) thus giving me
roughly 90 degrees of coverage att 47 Cd on RED and about 75 Cd on
Green. .

While having a meter may prove the point that it meets the FARs, this
is one I will defer to my favorite movie of "Treasures of the Sierra
Madre" and replace the word badges with the word meter.

Here's from the FAR's 23.1391

Well done Jose! I was affraid (from other sop engineering I've seen
here) that people thought that the FARs didn't apply to OBAM
aircraft lighting. I've spent far too much time and money trying to
design appropriate LED position lights. Looks like you got it in
one.

Many thanks,
Tom Costanza

aircraft lighting. Looks like you got it in one.<SNIP>

One night at a Holiday Inn Express can do wonders. Seriously now, I
would not endorse anyone building their own ignition system or buying
an industrial press to forge their own pistons. But these simple
things are not critical and can save the builder a lot of money to
spend on an EIS or a Moving Map GPS. It's not that I am cheap, I
earn a pretty good living as a DataWarehouse designer and
Administrator, but Lindbergh made it across the pond with next to
nothing and that's what I try to keep in mind when I get the fever for
gadgets in the pursuit of my next $50 burger.

Jose,

Did you notice these?
http://superlumination.com/fixtures.htm

For the price It might be worth it to order one or two to check them
out. Also did you consider the idea of putting plexi mirrors on either
face of the wingtip?

Great find! Their set up is 3 times brighter than the Sunbrites. I
ordered more lamps to experiment, including miniature lamps (194 type)
I may embed on the wingtips trailing edge and eliminate the tail
lights all together and saving a couple of pounds in wire and fixtures
(not to mention the wallet).

Thanks,
