I guess I should throw in my two cents here because I recently flew my L4P
with my own Landing light installation. I used the newest version HID from
Sylvania called Xenarc.
http://www.sylvania.com/xenarc/x1010.htm
If your persistent at the website you will find all the technical information
and the on-line price of $547.00 for the 2 light Kit.
This is an automotive light Kit that has two 2.5" x 6.5" rectangle lights and
two ballast's, and one remote control (which I didn't use) intended for auto
installation without running wires through the firewall.
I installed the two lights in my right cowl air inlet back against the
baffle. I put one on top of the other and adjusted the top one to shine down
and the lower one to point more straight down the runway. I made simple Al
brackets that hold them from the side and attach to the baffle. So far they
work exceptional. Most people I talked to said that the standard L4 landing
lights were weak and they never saw a plane with too much landing light. The
lights put out a rectangular pattern and with one down and the other out they
complement each other. I thought that with them back that far in the cowl
that there would be no light to the left side of the runway but they light it
up fine, leaving a shadow of the prop spinner toward the left. I use them for
recognition lights and everyone tells me they see them from very far away.
The technical part, as I understand it, is that these are the 4 Th.
generation in HID Xenon lighting, meaning that they mount the High Frequency
module in the base of the bulb so you don't have the HF line limitations on
length and shielding. They still have the remote Ballast but the line can be
longer and is smaller in dia. Also, these bulbs burn at a color temperature
of 5400K* Vs 4200K*. This is a measure of color and is so bright that for the
auto application they had a ceramic shield over the bulb so an on coming
driver is not blinded. I took one off and left the other on to see the
difference. From a projected light standpoint it made no difference but the
vibration from the engine dislodged this cover inside the one light only
after 10 hours, so I remove it also. The heat, as I understand it, is
proportional to the Wattage and at 35 watts there is less heat. I tried these
on the bench and they never got hot. The bulb has NO filament and therefor
should take more vibration and has a longer life, they say 3000 hours. The
lights have to fire up with 20,000 volts and after they are started they
reduce to 85 volts and a very small amps. I never thought that they would
work with a pulse lighting system but I tried turning them off and on very
fast and it worked very good. I suspect that once they have started that they
will start without going through the High Voltage start.
Thanks to the Lancair List for all the past help, I haven't contributed that
much.
