Hi all,

I have a Europa and I have decided that the only way I can get a decent taxi
light is to put it in the cowl. There isn't a lot of internal "Real Estate"
and I am looking for a small diameter HID light. Creativair sell as nice
one, but its OD is 4.46" which might be a bit big. I would be interested to
know if anyone else has sourced a smaller diameter HID light. Any
recommendations would be appreciated.

Thanks, Paul

Hello Paul

"I am looking for a small diameter HID light"

Hella makes a Xenon with a smaller diameter. I think that is what Wicks
sells:
http://www.wicksaircraft.com/
http://www.wicksaircraft.com/catalog/product_cat.php/subid=4546/index.html

One concern that I never got a good answer, will the frequency of the
Hella interfere with Avionoics?

We did some fooling with lights not too far back, no HIDs or Xenons.

Bottom line is it seems for especial landing, and taxi that the larger the
reflector the much more better it will illuminate what pilots wanna see.

The I think it was a 5 inch standard 12 volt landing light as used in a
Beechcraft was the absolute hands down winner. The next size down, think
3.5 was very good. Hmmm, I forget if i tried in the 3.5 a 100 watt and a
50, or perhaps it was a 50 watt and a 25. I forget, but the one with half
the watts was just a tad less overall.

We fooled with a borrowed box of 50 and 100 watt truck and car lights.
They were small in diameter, and just went from marginal to very poor.

The aircraft and halogens throw out some heat, so need to watch that.

You interested in a joint venture?

On our Mono need to fit some landing/taxi lights. Considering fooling
with:
http://www.besthongkong.com/index.php
Pro - Light 3 and 5 watt (10 watts on way??)
http://www.besthongkong.com/index.php?cPath=19
and 100,000 MCD 123 degree
http://www.besthongkong.com/product_info.php?cPath=3&products_id=34

Above not too much heat and fit in outrigger fairing?

Some dumb thoughts I have been having is to have a servo to move
illumination from landing to taxi mode. More dumb thoughts is to
incorporate a model aeroplane heading hold gyro, where you can choose
elevation and hit hold, now point nose up or down and beam stays focused!
Even some much more dumber than dumbness, can incorporate a yaw heading
hold gyro, that would allow S turns and or crab for landing and have beam
trained where you want in 2 axis. The Futaba technology heading hold gyros
does not use piezo, and heat/cold/calibration problems are supposedly
eliminated.

Anyway Best Hong Kong prices are very low, for a hundred 100,000MCD 10MM
are $.48 each. Have to fool with, but 3 or 4 in series are only 20mAs.
Lets say 3 in series and 33 in parallel=99 LEDs. Then 33 * 20 mAs = 660mAs
or .66 amps.

I have fooled quite a bit with LEDs on models, 10,000MCDs and results are
beyond impressive. My gut is 99 100,000MCD, or lets not push and use them
at 80,000MCDs, results may be???? Again these are $.48, I was paying over
$6.00 for the 10,000MCDs.

You can mix and match wide and shallow angle LEDs. Their offered Pro
Lights are wide angle, but aiming backwards into a parabolic reflector???

Hello Paul,

check

the DE series HID lights are 76mm diameter or about 3".

PIAA makes several small form factor, high output lights for
automotive use. I have been using one for over a year with good
results.
